Recently after I restarted my computer, it was giving "Low Disk Space Warning" . I did not care and because of that /var/log became %100 and I could not open my OS. So I deleted some files under /var.
Now it is %95 but it still gives that warning at beginning. You can see in picture after I clicked "examine" in that warning:
This is the size:

I did not know /var would be used so much. That is why i had given only 5.7 gb.
Biggest files in /var:
✘ canerveg@canerVegan ~ sudo du -h --max-depth=6 /var | sort -h|tail -n25
6,1M /var/cache/cracklib
6,4M /var/lib/gdm3

2,1G /var/lib/snapd/cache
4,3G /var/lib/snapd
4,9G /var/lib
5,1G /var
I think i can delete this safely:
2,1G /var/lib/snapd/cache
but why do I have to delete those? If I knew it would go so high, I could give more size. Should I increase size because I have
/dev/nvme0n1p6 149G 34G 107G 25% /home
but it will be risky to shrink/resize.
Those are snaps:

Here it removes old versions:
https://www.debugpoint.com/2021/03/clean-up-snap/
but I am thinking of removing snap completely. I can install whenever I need to install something from snap. What do you think of that?
software updater is downloading some updates now but it also decrease the size of /var. So, I cant download any apt bigger than 5 gb becase I have 5 gb /var?
I went to software center. clicked installed tab and removed all wines. There were 3 wines. I don't know why I installed those or an application maybe installed to be able to work.
Now it seems better:
