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.

Recovering from an openSUSE Tumbleweed update (lemmy.ca)

Zoom is vital to my job this month and prior to an update last week I had the openSUSE version of Zoom's RPM installed and working fine.

I updated my Tumbleweed installation to openSUSE-20240704-0 last week, after which Zoom started crashing when sharing a screen. There was a message in the logs about the library libqt5qml.so and I thought I could fix this by backing out either the update for the libQtQuick5 package in particular, or just booting from the pre-update snapshot.

To make a long story short, I ultimately installed the Zoom Flatpak and resolved to get back to this when I had a bit more time.

My question - Can people suggest the right way in openSUSE Tumbleweed to handle the situation where an update breaks something on the system?

Assuming libQtQuick5 was the updated package that was at fault here, is there a way I could have downgraded just that package? Would booting from the pre-update snapshot and then just carrying on with my week have been a reasonable way to proceed?

To be clear - I'm not so much concerned about Zoom, I'm more curious about how to use the openSUSE Tumbleweed tools to recover from updates that cause problems.

Thank you!

If a tumbleweed update causes issues, then rollback to a previous snapshot where the issue was not present. You should: reboot into the preupdate snapshot, which will be in read only mode; then launch zoom and check it works without error; then in a terminal enter sudo snapper rollback, which creates a read write copy of the good snapshot; reboot and your computer should be as if you never did the update.

The next question is about updating again in the future and if zoom will break. If you update again in say a month, the issue may not occur. It's hard to say. Otherwise, if you can figure out which library packages caused the problem, you can lock them in yast so that they do not update on zypper dup.

I had a similar issue with zoom in the last few years. If zoom stability is essential for you, just use the flatpak. The web client is an option too.

Had an issue many many years ago with TW where X11 was completely broken on my system. I just did a btrfs roll back to prior to the update and then updated like a month later
