Solved Failed Install (Racknerd KVM VPS Ubuntu 22.04)

[superhua]

On a fresh Ubuntu 22.04, Cloudron fails to install. Installing on a fresh Ubuntu 20.04 succeeds.

Errors at the end of the log:

I've looked at other failed installs with 22.04, but am not sure of next steps.

Thank you.

On which server provider or virtualization technology is this happening?

[superhua]

@nebulon This is on Racknerd KVM VPS.

(I'm using Cloudron successfully on this platform, but only with Ubuntu 20.04.)

Thank you.

Looks like their Ubuntu 22 image requires some custom fixes then. Do you see further errors in /var/log/dpkg.log to get more information on what exactly failed?

[superhua]

@nebulon Looking at dpkg.log, I'm not seeing any errors or fails.

[nebulon]

Just to be sure, have you tried the setup again and it fails the same way? Also maybe give the server some time to startup completely before running the Cloudron setup script. Sometimes the cloud-init scripts from the provider are still running while SSH already works.

[superhua]

@nebulon Alas, yes. Even after reinstalling 22.04 and waiting 10 minutes, I still receive the same error.

I may just install 20.04 and go from there since I know 20.04 works.

Thanks again for your help!

Update: I installed Ubuntu 20.04 and then upgraded to Ubuntu 22.04. The Cloudron install then worked!
