Apps Stuck Updating - Cleaning up old install - even after stopping/restarting task

@subven I think is not Netcup related issue.

nebulon

So we had an instance which seems to not hit this issue anymore by making sure the kvm version is updated. On netcup this apparently means to shutdown and boot the instance through their control panel. A simple reboot/restart will not solve it. Maybe anyone here facing this and being on netcup could attempt this so we get more info.

I just did that (a power cycle via their scp server control panel), let's see if it resolves the issue for me...

The same problem occurs on my Hetzner and Contabo servers.

Weird, got three Netcup instances and only ever hit the issue one. Plus other people seem to be hitting it with other providers.

PS: the instance I restarted earlier today and that was working now hangs again on updates. Restarted again and now working fine...for some time...

Good news is that ever since the last reboot my instance stopped hanging (it's been 4 days). The only thing I did compared to the other time I rebooted is that I updated all apps manually to their latest version and so had no more update to do (the last app was WP unmanaged). Ever since updates have been working fine.

I had actually already done this from Netcup SCP the first time I hit the issue but it hadn't solved for me.

Ok, so one thing which I have noticed is common is that the kernel is 5.4.0-132-generic (output of uname -nar and Ubuntu 20.04.5 (lsb_release -a). Can others please confirm what kernel and ubuntu they are on?

@girish is there a way to check what I was running prior to upgrading to22.04?

@girish
All three instances are on kernel 5.4.0-132-generic
Two instances (including the one that used to hang) are on Ubuntu 20.04.3
One instance is on 20.04.4

girish

@humptydumpty no, I think not. Are you still facing this issue? What's your current kernel and ubuntu release?

subven

@girish Netcup RS 4000 G9 Ubuntu 20.04.2 Kernel 5.4.0-131-generic - no issue.

humptydumpty

@girish 100% fine since upgrading to 22.04 with the fixes you did when you SSH'd in.

Linux vmi5XXXX5.contaboserver.net 5.15.0-53-generic #59-Ubuntu SMP Mon Oct 17 18:53:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.1 LTS
Release:        22.04
Codename:       jammy

So, the issue was just reproduced on our DigitalOcean demo cloudron. That is also running ubuntu 20 and 5.4.0-132-generic

humptydumpty

@girish I'm in the clear but for others, what would be the best way to upgrade to 22.04 without running into docker hangs like I did?

martinkbs

In my case, the servers have the following configurations:

Contabo
Ubuntu 20.04.3 LTS
5.4.0-132-generic

Hetzner
Ubuntu 20.04.2 LTS
5.4.0-132-generic

Alright, this seems to be a kernel issue. Other programs are experiencing similar:

GOMAXPROCS=1 apparently alleviates the issue. So, I will try this one.
