Hello, i am using Proxmox more than a year now for an Homeassistant installation.

Now i want to set up a new container and i saw that i can´t update the system.

I received the error "You don't have enough free space in /var/cache/apt/archives/."

I searched in the net and found some solutions with
"sudo apt clean"
"sudo apt autoremove"

The problem is sudo is not installed and if i try, i get the same message
You don't have enough free space in /var/cache/apt/archives/ to install sudo.

root@pve:/# df -h

root@pve:/#


I see that there is no space left on:
/dev/mapper/pve-root

I try to find a solution in this forum but i cant see it.

Please know, that i am a linux beginner (Install only with copy and paste :)

Can sombody help me please ?

Thank you and best regards
Andreas


I deleted 3 other containers which were not in use
But same result

I see you are using /mnt points for NAS. Most likely you wrote data to the local /mnt folder instead of to the supposedly mounted NW storage (was inaccessible at the time).

Showing output for: du -h -x -d1 / will confirm this.

Hi thanks

Your /mnt is not the problem - 12k is normal. But /var has 92G - that is using most of your total space. Backups maybe in /var/lib/vz/dump/ ? Check & delete / move to another storage as appropiate.

Check size with du -h -x -d1 /var/lib/vz/dump/

Most all space of your 94g "/" is used here in that dump folder. See there what you need further and better move that to your nas space.

@ARO56 got past this, but for someone else who might find this and have a similar question...
You don't need to sudo apt ... because you are already root, sudo lets you execute a command as if you were root. PVE's >_Shell buttton is equivalent to sudo su - root which gives you a shell as if you logged in as root. (That may even be what it does behind the scenes. I don't know as I am not a proxmox programmer.)
