How to back to a snapshot problems with Tumbleweed update to kernel-default-5.3.8-1.1?

English Install/Boot/Login

After the update to last version my computer is unusable, but the the last snapshot before the update is work.
How can I boot up right on to this snapshot without to go ever to snapshots option at boot menu and select an given snapshot? I must go back to version with kernel version 5.3.7-1-default, the last snapshot before update.

I was reading about snapper but I didn’t find cases when was necessary to back to an early snapshot.

I would like to get some documentation to read about the snapshot management.

Personally, I don’t use btrfs / snapper, but this documentation may provide you with answers.

Hi
Or install tumbleweed-cli and rollback that way, I don’t use snapper, but have used tumbleweed-cli to sort out a Mesa issue a few snapshots back…

https://github.com/boombatower/tumbleweed-cli/wiki/Installation-and-usage

Or, just boot with the older kernel from the Grub options?

So what is your issue, graphics?

Hi,

I do use snapper, almost daily ( install software to help others, rollback to snapshot before to remove all of that when done ). Have a look at the snapshots by


su
snapper list

Look at the dates, and the snapshot number. Let’s say the last snapshot before the upgrade was # 1234, then you would do


su
snapper rollback 1234

This normally takes only a couple of secs. Reboot and the default Grub entry should put you back on the previous state of the fs.

I’m at another version of kernel by now, I did entry via grub entries, but I want to find a way to make this actual snapshot, that I can list with snapper list, my main ‘version’ of system.

Doesn’t seems graphical issue, but the laptop is with four cpu core with 80% to 100% usage, and very slow although I’m not using nothing with more than 15GB free of RAM memory.

I will look to tumbleweed-cli also, until to know how to make that without crash the system, I keep continue to boot up for early snapshot by grub entries.

PS: I am very pleased with Tumbleweed, It is the first time I go through such a problem, and I make updating all the time in my system, but as I come in this scenario, I would like to understand these snapshot concepts if is the aim for these situations, as apparent to be.

It’s work perfectly! How I think that is the objective of snapper by my first reads. Let me know how to find a documentation to usage like you said, manager software installation and other stuffs. I find the link passes in one of this previus post but I imagine that has something more ‘hands on’ in some scenarios, and some links are broken.

Thanks by answer and thank to all guys that gave me some good options!

No need to go backward if the Kernel is the problem, you would loose the dup content (20191104-0). Delete the Kernel:

su -
zypper -v rm `rpm -qa *kernel* |grep 5\.3\.8\-1`

Example and normal reading:

# zypper -v rm `rpm -qa *kernel* |grep 5\.4\.rc5\-3`
The following 5 packages are going to be REMOVED:
  kernel-default        5.4.rc5-3.1.gc8cf7fe
  kernel-default-devel  5.4.rc5-3.1.gc8cf7fe
  kernel-devel          5.4.rc5-3.1.gc8cf7fe
  kernel-source         5.4.rc5-3.1.gc8cf7fe
  kernel-syms           5.4.rc5-3.1.gc8cf7fe
Yes

Restart and the Kernel should be gone from the Grub menu.

Which would leave kernel related packages in …, like f.e. nvidia drivers.
Just saying

We were assuming that the OP was able to boot in the previous Kernel to isolate the bug. The 33 related packages last a few weeks. This is the content of the last snapshot. Among other, Grub, Mesa, Python can break the system and of course the Kernel. Going back to a previous snapshot just sets the bug in pause mode.

The following 4 NEW packages are going to be installed:
  libbrotlienc1 libMagickCore-7_Q16HDRI7 libMagickWand-7_Q16HDRI7 systemd-network

The following 2 packages are going to be REMOVED:
  libMagickCore-7_Q16HDRI6 libMagickWand-7_Q16HDRI6

I can agree on the last bit. But it at least would not break an openQA tested snapshot. Skipping a couple of snapshots to wait for a bug being fixed is not bad practice. (Re)moving folders that belong to packages is. IMNSHO.

You have a conservative approach, not to say static mode because if the OP would be able to boot in the previous kernel, I would suggest I’m compiling the highest one available 5.3.8.-7.1 (5.3.9-x.x has been already out) to see if things are better. If not, there’s the high speed train station @ 5.4.rc6-4.1, they’ll all be there in about 2 weeks.

This is a rolling release among the only one that follows the train, not a small village in Legacy Mode.

Hi!

I will try in a Virtual Machine that I keep updated to make some tests.

13

Are you able to boot in the previous Kernel? If yes, run the given command line in post # 11.

Compare to others, is reading abnormal or does it wake up the new Kernel?

14

I did lock any change the packages at Mesa driver and I did update the system. The problem wasn’t the Kernel as someone ask in previous posts.

The management of snapshots it’s the best alternative for me to work around updates problems since this post. As I said I never had problems with Tumbleweed and ever make updates as soon as they are released, with snapper I’ll keep do that.

For know the video driver it’s lock, but soon as possible I’ll try to update and if had some problem Snapper to recue.

I did already talk to my boss about snapper, it’s good to have such tool in our servers instead to deal directly with LVM stuffs.

Thanks by all replies and options given.
