I already reported it in the RC version [NAS-138028] and it should be fixed for 25.10.1 but as far as i’ve seen didn’t make it in todays release.

The upgrade went smoothly with no problems.

What happened? :frowning:

7

Ruh roh. Boot device isn’t showing up at mount time. Give it another reboot and check, still gone?

8

Selecting 25.10-RC on the GRUB menu: server boots correctly.

25.10: this error above.

9

Remove the 25.10.0 boot environment from System → Boot and try the update again. Lets see if it repeats.

Containers is still marked as experimental.

Is this state due to change at some point. I am currently using jailmaker which is (still) working well. I would like to change - but am reluctant to do for something that IX may rip out of the product as its experimental

14

switched to an lxc when i updated to the rc version because i couldn’t get gpu passthrough to work with jailmaker and 25.10 and i haven’t had any instabilities with my lxc. it just works.

We’d like to see users test it extensively and then make the change.

We don’t know of any major issues, but its a deployment model we have less internal testing of. Apps (docker) and VMs get most of the deployment experience and testing.

It is getting more testing than jailmaker…

16

Btw any eta when lxc will switch to libvirt? As far as I can tell it’s still using incus atm

17

I have a bug with the custom apps, they do not update from version 1.2.13 to 1.2.14. I have launched the update several times, there is no error but I still have the update notification and the apps are still in version 1.2.13

18

Please file a bug ticket with a debug

I ran into an issue with Apps service not starting, but yet it’s starting. See After 25.10 upgrade, "Critical Failed to start docker for Applications: Docker service could not be started" .

Update: The solution appears to be that I had to go into Apps → Configuration → Unset Pool, then Apps → Configuration → Choose Pool. All my Apps showed up in a “Stopped” state, so I had to select all, then start the applications. Thanks to @AdenMGB for that solution. I will be trying out the 5060 video card tomorrow.
