I'm a Windows guy but our Linux guy is out, so please excuse my ignorance here.

I have a server running 20.04 and it states that I have a lot of updates to apply. When I run the command sudo apt-get updates, it rolls through the updates and then errors out "Error writing to the output file - write (28: No Space left on device)

When I run df -H I see this:

administrator@ntpjjc1:~$ sudo df -H

Ok, it looks as though /var is the issue...

When I run sudo du /var -h dl I see that /var/lib/snapd is 1.4G in size and that /var/lib/snapd/snaps is taking up 712M.

When I try to run sudo apt upgrade I receive the following error message: "You might want to run apt --fix-broken install to correct these. The following packages have unmet dependencies:"

When I run sudo apt --fix broken install I receive the following error: You don't have enough free space in /var/cache/apt/archives

administrator@ntpjjc1:~$ sudo apt --fix-broken install

After this operation, 380 MB of additional disk space will be used.
E: You don't have enough free space in /var/cache/apt/archives/.

And finally, when I run sudo du /var/cache/apt/archives/ -h

dministrator@ntpjjc1:~$ sudo du /var/cache/apt/archives/ -h
4.0K    /var/cache/apt/archives/partial
20K     /var/cache/apt/archives/

So, my question is, how do I free up space so that I can install updates?

I have run the following commands:

sudo apt clean
sudo apt autoclean
sudo apt autoremove

When I run sudo apt autoremove I go back to the broken dependencies error mentioned above.

I seem to be in a circle but not sure what commands will work to break this cycle.

Thanks! -Mike

You have some old revisions of snaps that could be removed and would free up some space.

sudo snap remove core18 --revision=2538
sudo snap remove core20 --revision=1695
sudo snap remove lxd --revision=23991

These are the previous versions of those packages, which aren't needed. They're only kept around in case you needed to revert a broken package back to a working one.
