From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Preparing to move from Ubuntu to Fedora (lemm.ee)

Hi! I'm seeking some advice and sanity check on hopping from Ubuntu to Fedora on my personal PC. I've been using Ubuntu LTS for almost two years now, switched from Windows and never looked back. But I cannot say I know Linux well. I use my PC for browsing, some gaming with Steam (I have AMD GPU), occasional video editing, tinkering with some self-hosted stuff that is on separate hardware.

I don't like the way Ubuntu is moving with snaps. And LTS version falls behind too much. So I decided to move to Fedora.

My plan is simple:

  1. I will install Fedora on a fresh nvme drive. I want disk encryption, so I'm going to have LUKS over btrfs for /home, and the root will remain unencrypted.
  2. I will copy all files from old /home to new /home, with the exception of dot-files.
  3. I plan to make use of flatpaks, so I don't think configuration for my apps is easily transferable. I'll have to install and configure apps from scratch, unless I'll have to use an RPM package.

Does all of this make sense? Is there a way to simplify app re-configuration in my case?

And as I never used Fedora extensively (booting from live image doesn't count), are there any caveats I should be aware of?

Enable rpmfusion for media codecs and things like libdvdcss or unrestricted mesa drivers: https://rpmfusion.org/Configuration

https://docs.fedoraproject.org/en-US/quick-docs/installing-plugins-for-playing-movies-and-music/

Fedora comes out of the box with a curated flatpak repo. You might want to replace that with flathub: https://flatpak.org/setup/Fedora

Imho, there's no reason not to enable disk encryption for root. Luks configuration during setup is very straightforward.

If you don't have nvidia graphics, enable uefi and secure boot (no legacy options). Fedora works well with it out of the box.

[–] Pantherina@feddit.de 3 points 11 months ago

This is essential. sudo dnf install libavcodec-freeworld may already be enough if you dont need ffmpeg for anything.

Or you use ublue, where rpmfusion and ffmpeg are preinstalled.

Thanks! This is helpful

Why not move to Debian? Ubuntu was born in a time when Debian stable had a really long release cycle and wasn't desktop ready. But times have changed. Debian is a great desktop without all of Canonical's Ubuntu "experiments" like snap.

[–] GustavoM@lemmy.world 9 points 11 months ago (1 children)

This. Edit /etc/sources/apt, switch to sid, sudo apt update and you'll have "a better ubuntu."

[–] Pantherina@feddit.de 4 points 11 months ago (1 children)

Crazy, that works?

[–] GustavoM@lemmy.world 3 points 11 months ago (1 children)

Yep. Did this on my orange pi zero 3 (which has no support on Linux) and it worked. :^)

[–] joyofpeanuts@beehaw.org 4 points 11 months ago (1 children)

I second this. I have been using Ubuntu for at least 10 years by I really do not like snaps or flatpaks for that matter. So, after some disappointing attempts using Debian in the past, I had a new go at it 1-2 years ago and I was positively surprised: Ubuntu without the useless bloat - kind of normal because Ubuntu is based on Debian. For sure the my next PC will be using Debian: efficient, highly configurable, and quite user friendly once you understand it's ways of configuring things.

[–] pound_heap@lemm.ee 1 points 11 months ago

I see your point... I use Debian for my self-hosted environment, so having similar system on desktop may save some cognitive load. My main arguments against Debian are (maybe misinformed though):

  • ~~No btrfs support in installer~~ OK, Debian wiki says it's there
  • Major annual upgrades to keep up with stable look more scary than more incremental and frequent updates of Fedora. And using Sid as someone suggested sounds too crazy for main PC

So yeah, looks like it's just upgrades... Gives me something to think about while I'm moving my apps to flatpaks

[–] thayer@lemmy.ca 2 points 11 months ago (1 children)

That still wouldn't answer their dilemma of older versioning of packages, unless they went to Sid.

[–] Maestro@kbin.social 3 points 11 months ago

Debian stable has newer packages than Ubuntu LTS. Debian has pretty regular releases these days.

Why don't you install flatpak on Ubuntu, make the packaging migration before doing the OS migration so you can evaluate your workflow with the new packaging system? Afer you're used and confident with flatpak, backup and restore the flatpak folder into fedora and you transition should be smoother (don't need to worry with 2 stuff at the same time)

[–] pound_heap@lemm.ee 2 points 11 months ago

Yeah, looks like migration of flatpaks between OS is easy and makes sense a lot

[–] ObsidianBreaks@lemmy.ml 9 points 11 months ago (1 children)

Plan sounds alright. A couple of notes.

  • Don't forget your passwords and bookmarks stored in browser when doing the copy over.
  • Personally, I'd use Full Disk Encryption (FDE) because it's a default option on the Fedora installer and is more secure, and well-tested, and easier to configure.
  • For your planned installables, I'd keep a list of apps you regularly install in a file somewhere (even better would be a script which installs them all) then when you distro-hop it's easier as you can just change your script for whatever package manager.
  • Some of your apps will store their configuration in your home directory in a dot file, you might be able to copy these over one-by-one for each app.
  • Have you decided on Fedora Workstation or Fedora Silverblue? Each have their merits and demerits, and its worth investigating.
[–] pound_heap@lemm.ee 1 points 11 months ago

Thanks!

Bookmarks and passwords are taken care of. And for the apps I'll try to get migrated to flatpaks as many as I can while still on original system.

I also see that full disk encryption is being recommended a lot, and I don't have any solid reasons to encrypt only /home.

I have not given much thought on Silverblue. Is it "flatpak-only"? If so I'll need to go through my apps to see if that could work. And my backup strategy will need to change - I use Duplicacy that is not available as a Flatpak

[–] EponymousBosh@beehaw.org 9 points 11 months ago (6 children)

Honestly, if you like Ubuntu but dislike Snaps, Linux Mint might be a better choice than Fedora if you're not as comfortable with Linux. Mint is basically "Ubuntu without all Canonical's garbage."

[–] Interstellar_1@pawb.social 5 points 11 months ago (1 children)

I used fedora before I was comfortable with Linux and I didn't have any problems with it.

[–] jcarax@beehaw.org 3 points 11 months ago

I agree with this, Fedora is pretty boring. It's polished and well thought out. Just wait a few weeks before upgrading to new versions, but that goes for pretty much everyone besides Debian stable.

Flatpak apps will use the same dotfiles as apps installed via traditional methods, however the storage location will likely be different. Most dotfiles will be contained within their respective flatpak app directory under ~/.var, so you can cherry pick which settings you want to bring over.

[–] pound_heap@lemm.ee 3 points 11 months ago

Oh, that's neat! Thanks!

[–] NotAnArdvark@lemmy.ca 5 points 11 months ago (2 children)

Are you leaving behind the dotfiles because you don't want to bring over any of your old configuration?

For whatever it's worth, you can remove Snap support from your Ubuntu system. If you want more current software, AppImage and Flatpaks are good for that.

[–] avidamoeba@lemmy.ca 6 points 11 months ago* (last edited 11 months ago) (2 children)

Removing snap is somewhat unwise. Ignoring it is the safe way to go. Ubuntu might ship a system component you're not aware of via snap. If you kill snap support you may end up with a broken system. To avoid headaches, simply ignore snap.

[–] folkrav@lemmy.ca 14 points 11 months ago (1 children)

If one dislikes snaps, the even wiser choice is just skipping Ubuntu altogether.

[–] avidamoeba@lemmy.ca 0 points 11 months ago (1 children)

Yes. However the level of difficulty increases.

[–] folkrav@lemmy.ca 1 points 11 months ago* (last edited 11 months ago) (1 children)

Zorin, Mint and Pop all are Ubuntu based distros that replace snaps with flatpak by default. I don't know what would make any of those any more difficult than straight up Ubuntu. I'd even argue that most mainstream distros aren't any harder to use than one another. Most of the differences between traditional distributions are behind the scenes: package manager, init system, default applications/configurations...

Even Arch, which has a reputation of being "hard", isn't particularly hard to use. It's the lack of an installer that makes people freak out. The rest is just Linux. Once you plop in a GUI for package management and a proper desktop environment, from an end user perspective, nothing of it is inherently harder.

[–] avidamoeba@lemmy.ca 1 points 11 months ago (1 children)

Solving problems is what becomes more difficult. There's rarely issues with the happy path. The further away you move from mainline, the more components are different, the fewer of the solutions on askubuntu.com work by simply copy-pasting them. A novice user has no idea what the solutions do and why they don't work. Instead they have to keep trying other copy-pasta hoping some would work. At best taking longer to solve it, and at worst some copy-pasta breaking something on their system.

[–] folkrav@lemmy.ca 1 points 11 months ago* (last edited 11 months ago) (1 children)

Copy pasting random stuff from askubuntu is how you break your install in the first place. Novices don't "have" to do that, they get told to do it by randoms on askubuntu that should not do that. Understanding an issue is key to fixing it, regardless of the problem's nature.

I've yet to hit anything that worked on Ubuntu that didn't on Mint. Hell, I find half of what I need on Arch Wiki even when not using Arch.

[–] avidamoeba@lemmy.ca 1 points 11 months ago

While you're right, this expectation is unrealistic. Not only is it unrealistic for novice hobbyists, it's unrealistic for people who use Linux to do other things, not for the sake of using Linux or learning its innards. For example my family members who use it for work an leisure. They couldn't and won't be bothered with learning how hibernation on Linux works. They want hibernate to work. The have me to make it work for them but folks who don't will go to askubuntu.com, grab a well upvoted answer and copy-paste it straight into a terminal.

[–] pound_heap@lemm.ee 1 points 11 months ago

That's what I mostly do now. But it requires some extra work, as some apps are not available in Ubuntu DEB repository. Also, I don't like the approach that Canonical takes, pushing snaps so much

[–] pound_heap@lemm.ee 1 points 11 months ago

Well, my original plan was to copy configuration over after I install apos that are not available as flatpaks. Looks like I can copy configuration for those too, just to another location

[–] jman6495@lemmy.ml 3 points 11 months ago (1 children)

Yes, but if you intend to mainly use flatpak you might want to try fedora Silverblue

[–] possiblylinux127@lemmy.zip 1 points 11 months ago

I personally wouldn't recommend that. Its all personal option and there isn't one that's better in a general sense

[–] just_another_person@lemmy.world 3 points 11 months ago (3 children)

This has been solved for the most part: https://github.com/popey/unsnap

The few system snaps for things like Gnome updates shouldn't impact performance.

[–] NanoooK@sh.itjust.works 6 points 11 months ago

This makes me think of the tool for windows to remove the bloat.

Just use a distribution that doesn't force snap down your throat.

[–] Pantherina@feddit.de 3 points 11 months ago

Great tool! Funny that after removing snapd all those mounts appear. Afaik a reboot solved this for me, did it on a Ubuntu install already, and everything works fine

[–] pound_heap@lemm.ee 1 points 11 months ago

Interesting. It says that the project is in pre-alpha stage... not sure if I would be able to verify the scripts it generates

[–] Pantherina@feddit.de 1 points 11 months ago

I want to write a script for this app config backup stuff once. Also working on Windows, but maan I have low motivation on that one haha.

You can use your configs, relevant for me are

  • firefox: ~/.mozilla/firefox can stay if you keep using Fedora Firefox
  • thunderbird ~/.thunderbird/ copied to ~/.var/app/org.mozilla.Thunderbird/.thunderbird
  • libreoffice from somewhere to the flatpak directory (useful if you have a custom dictionary, autocompletions or interface)
  • qgis, element

Many other apps use the same structure with a profile folder so easily transferrable.

In firefox and thunderbird you either delete the whole contents and replace everything, or you only paste the contents of your *-default-release folder in the new default release folder, after deleting its contents.

Flatpak apps need to be ran once, to create the ~/.var/app/ subfolder. After that you can close them and replace everything. If you delete that folder, or move it somewhere as a backup, the settings are reset to default. Pretty cool.

If you want to try the new image-based distro model, I can highly recommend ublue and their installer. It has all the codecs out of the box and also an nvidia version which will never break basically, if it should, you can roll back to your previous system that worked.

It is a very cool distro model, and ublue has loots of customizations. If you never tried KDE I recommend their kinoite-main (do not use any -nokmods, these images are outdated as they removed kmods from -main !)
