I'm trying to update promox, but am getting an error and not really sure how to fix it.

Code:

TASK OK

I also checked the "apt-key list" referenced in the error and there was this warning at the top

Code: 
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

This could possibly indicate that your file system is out of space, or that tools cannot write to the /tmp dir for other reasons.

What do the following two commands output?
Code: 
df -h
ls -lad /tmp

Thanks for the quick reply. I'm newer to proxmox, so forgive me in advance if I'm using lingo incorrectly. Since I have my LXC/VMs on another NVME, the 1tb SSD that promox was installed on had default partitions of 100GB for local and 900GB for local lvm. I removed the local lvm partition and allocated to the local to use for backup.

df -h returns the following. Since I only have promox installed on the main ssd, it's showing 1% usage.

Code:

and ls -lad /tmp returns:

drwxr-xr-x 7 root root 4096 May 17 22:21 /tmp

Also, not sure if this is helpful, but I ran ls -la /tmp and it returns the following

Code: 
total 28

Ok, you got still plenty of useable space left, so that's not the problem.

Hmm, /tmp should be writable by all users on the system (including apt), but it seems like it isn't.

Can you try changing that? E.g., by executing chmod 1777 /tmp as root, then you can try if the apt command works again.

Just to be a little bit picky: it should be chmod 1777 /tmp. This is the default, it will set the "sticky" bit for security reasons. (Already existing files in /tmp/* will learn this on reboot...) The result looks like:
Code: 
drwxrwxrwt  24 root root 20480 Mai 18 09:27 tmp

Best regards

Yeah, you're definitively right – thanks for pointing that out!
 
@t.lamprecht Thanks, this did the trick. @UdoB , I appreciate you clarifying the syntax because as a complete noob to proxmox and linux in general, it would have taken me some time to figure that out.

To be honest: I am sure @t.lamprecht knows the syntax - definitely ;-)

My point was that "777" would have solved your problem, but it would be a bad solution as it raises a security hole.

I'm happy you get a step forward :)

What would you recommend I change it back to after updating? I can just change it to 777 only when I'm updating

??? "1777" ist the recommended value.

Code: 
chmod 1777 /tmp

And then reboot - as already existing files/folders are not being corrected by that command.

In a Homelab this is probably no problem at all! To misuse the absence of that flag you need to be a user logged in to that node....

Got it. Thanks. I have a small and humble home lab that isn't exposed to the internet with the exception of Plex port that runs in an LXC.
