Root File System Full

[charmingfox2976]

I have had a message that my 'root filesystem is full'. At the moment I Cannot install new and updates. Please view the terminal screen image enclosed via attachment.

Try this first:

sudo apt autoremove

Then run your update and upgrade command again.

I would also recommend running this:

sudo apt clean

If neither of the commands we suggest solve it, then please post the output of this command:

df -hT -x squashfs -x tmpfs -x devtmpfs

Nice addition Rubi1200, I failed to read the bottom line For /var/cache/apt/archives/

One way that a system can get full is with excessive log files so you might check to see if you have particularly large log files. If you have been experimenting and getting a lot of errors this would be a good place to look.

du -h /var/log

Both apt autoremove and clean didn't work. Please find a copy of the terminal output enclosed via attachment after I inputted the two commands you have suggested.

Please do not post screen shots unless gui and then only as attachments. Hard to read especially for older eyes.

Easy to add code tags around text or terminal output with Forum's Go Advanced editor and # icon.

I sometimes use the quote icon in quick reply and just edit quote to code.
If using Quick Reply then [CODE] at the beginning and [/CODE] at the end.

If you use the Forum's Go advanced editor, you can use the paperclip icon to attach screenshots or other info. Post #4 , also no larger than1024x768 if photo

I like to use ncdu starting at / to find large folders & files. Saves running multiple du commands.
sudo apt install ncdu
cd /
sudo ncdu
arrow, enter & q keys to move about

ncdu 1.15.1 ~ Use the arrow keys to navigate, press ? for help

You really need to use code tags, most of us will just ignore until you do that. oldfred has showed a few ways to do that.
Did you peek inside of:

185.3 GiB [##########] /.local
30.0 GiB [# ] /.var
11.5 GiB [ ] /.cache
2.8 GiB [ ] /.config

I would first look there to see if anything there can be moved(To a back-up Drive) or just deleted.

Should be able to clear the .cache right now without any need to investigate.

.var seems really big, it's usually the flatpak directory in your home folder, really. But that's massive, like you have 100s of flatpak apps installed or something.
or have flatpak apps that are saving data to the wrong location.

.local might be the trash folder, look in .local/share/Trash. Could be you've only moved to Trash but have not emptied it yet.
