Can't access Proxmox shell or the VMs from within Proxmox

[fabiolanza]

Hi, I always used Proxmox without any problems. Without doing any configuration changes, I can no longer access the Proxmox shell or any of the VMs from within Proxmox (I still can access the VMs via RDP for example).

I am using the root account - always have. Any guests on what could be creating this problem?

I shutdown the physical server and turned it back on, but the problem persisted.

Here a screenshot with the error code:


Thanks,
Fabio

check the journal while you try to open the shell:
* connect via ssh and run `journalctl -f`
* try opening the shell in the GUI

that should point to any potential problems

I hope this helps!

Hi @Stoiko Ivanov , this is the output of the journal. Do you see any hints on the issue?

please post `pveversion -v` (and make sure you're on the latest available updates)
if this is the case try running:

/usr/bin/termproxy 5900 --path /nodes/rosa --perm Sys.Console -- /bin/login -f root

in a shell and paste the output (if possible in 'code' tags instead of 'icode' as those are easier to read for multiple lines)

Hi @Stoiko Ivanov , I launched the command "apt upgrade" and now everything works again. However, I see that Proxmox is still running on version 6.2-4. How can I upgrade it to version 6.3?

Thanks,
Fabio
