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

[girish]

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

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

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

@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.

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

@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?

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:

• https://github.com/prometheus/node_exporter/issues/2500

• https://github.com/opencontainers/runc/issues/3641

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