Tricia 19.3 Login Loop After 100% Capacity

[Kenkeknem]

I have looked at other threads with a similar error, I have booted to terminal with Alt+Ctrl+F1 and followed the directions. I have a rather different set up.
I boot to a 250GB SSD (that seems to be 100% full due to a blunder of my own making), my Home volume is on a 1TB spinning disk. I have several drives in this computer for data storage of my YouTube videos. I also have other computers on a network that share these drives so I can video edit on any machine. I was transferring my 2TB drive contents to a 4TB drive using Gsync. Well really I was filling up my SSD because I was not actually mounted on the 4TB drive I was dumping the files into /media/barry/4TB folder on the SSD. I have deleted the contents of the /media/barry/4TB but I still can't get my desk top to load. What can I safely dump on my boot drive so I can remedy the 100% full situation?

If you find a need to make space on your / partition, these are safe commands to use to do so by copy and paste, one at a time, into your terminal...If you have never done these, you might find quite a bit the first time, but very little thereafter.

Kernel and other Cleanups after Deletions:

Code: Select all

sudo apt autoclean

Code: Select all

sudo apt autoremove --purge

Clear the Thumbnail Cache:

Code: Select all

rm -v -f ~/.cache/thumbnails/*/*.png ~/.thumbnails/*/*.png

Clear Miscellaneous Detritus:

Code: Select all

dpkg -l | grep '^rc' | awk '{print $2}' | sudo xargs dpkg --purge

Clear DNS Cache:

Code: Select all

sudo systemd-resolve --flush-caches

Flush Journald:

Code: Select all

sudo journalctl --rotate

Code: Select all

sudo journalctl --vacuum-time=1s

Do this last one ONLY if you are using an SSD drive:

Manual SSD TRIM:

Code: Select all

sudo fstrim -av

Thanks for the tips. I did manage to free up a few gigs of space with your suggestions but still can't load the graphical interface, I will do some more searching on here because what was removed should be enough to get Cinnamon to load.

Wow! what a fight but I managed to get my desktop back.
All the files were in /root/.local/share/Trash/files deleting these files just made a folder .0Trash so the drive was still full. I managed to boot in with a USB and navigate to the mount point and use baobab as sudo then shift delete. Trying to navigate in to the /root folder was a challenge as when I used "sudo cd" it would just error out.
