It has finally happened...not surprised though.

Managed to just about see it here in Dublin.

Context:

I updated my system last night (EndeavourOS) and it looks like the kernal didn't update correctly. When I restarted the system and entered my password for the encrypted drive, I get an error:

[FAILED] Failed to mount /efi
See 'systemctl status efi.mount` for details.

I can't remember the commands I used last night but I was able to check the version of the kernel I am using currently - uname -r I believe - and what is installed. There was a difference in versions.

Trying to fix the problem:

I attempted to chroot into the system via a live USB - tutourial, arch bbs & arch wiki.

However, when trying to mount the drive (/dev/sda2) I get an error message: mount: /rescue: unknown filesystem type 'crypto_LIKS'. I tried using cryptsetup luksOpen' and 'udisksctl unlock -b' but both return a similar error saying it is not an encrypted device. See fdisk -l results below:

Snapper Snapshots:

I recently setup snapshots with Snapper since I'm using BTRFS. From what I understand, I can just roll back my system to before the system update (it takes a snapshot before and after installing anything) but I got confused on how to do that last night - troubleshooting at 2AM with a lack of sleep will do that...

What is the best way forward? I'm happy to provide more information if it helps.

EDIT 3:

I think I have fixed it. I have chrooted and am busy running sudo pacman -Syu

EDIT 4: /efi still fails to mount.

My wife and I have just recently had our first child and I'm looking at getting a decent baby monitor (or security camera) setup.

Our place is not very big at all (think a studio with a separate bedroom/bathroom). I was given a cheap security camera to use for now but I want to start planning for when we move into a bigger apartment (security cameras) and a generally better system for monitoring our baby when we are in another room and cannot hear.

Should I invest in a baby monitor now or would it be better to invest in a decent security camera system instead?

I'm based in the EU and am quite tech-savvy so I don't have a problem setting things up myself if it means a better system.

I've been using Linux for about 7 months now and have become a lot more comfortable using the terminal but I feel like there is more that I can learn.

Most of my work is done in a browser or DaVinci Resolve. I do try to use the terminal where possible but it's limited due to my workflow.

Are there any interactive sites where I can practice/learn the terminal? I'm going through Linux Survival at the moment.

EDIT: I forgot to add some important details.

I don't have a massive need for the terminal for my current workflow but I think it is important to know (looks good for any future job applications as well) and expand your knowledge on things that interest you when possible.

In the future, I hope to have a home lab/NAS running Linux. I will most likely SSH into that and I'd like to deal with any issues via the terminal.

I use Arch btw (technically EndeavourOS)

I was trying to find some medicine today and realised I need a better system to organise what I have and know what I don’t have. Currently, everything is kind of thrown into a drawer.

Ideally it will be seamless enough that it doesn’t become a chore when I need to add or remove something.

EDIT:

Thank you for all the suggestions thus far. I just want to make a small clarification.

I'm not looking for a system to organise the medicine/vitamins that I am currently taking (although the ideas provided are super useful). I'm thinking more along the lines of a "stock management" system for the stuff I am not actively using.

I came across this software as an example.

Just after seeing this in the shop.

I've been seeing a lot of talk about CachyOS recently. Has anyone here tried it? It seems interesting and I might give it a go (currently on EndeavourOS) on a spare drive in my PC.

I often hear folks in the Linux community discussing their preference for Arch (and Linux in general) because they can install only the packages they want or need - no bloat.

I've come across users with a couple of hundred packages installed (likely fresh installs), but I've also seen others with thousands.

Personally, I'm currently at 1.7k packages on my desktop and 1.3k on my laptop (both running EndeavourOS). There might be a few packages I could remove, but I don't feel like my system is bloated.

I guess it's subjective, but when do you consider a system to be bloated?

I'm asking as a relatively new Linux user - been daily driving for about 7/8 months
