Full 20gb root partition after 20 days of usage

Question

I installed ubuntu 19.04 20 days ago. My root partition has a size of 20gb and it is almost full. Here is what Disk usage analyzer outputs. According to dua the folder /usr/lib is taking up the most space. I tried cleaning up with apt (clean,autoclean,autoremove),with bleachbit, removing old snap versions, general suggestions but have still little space left.

Should I resize my root partition?

Edit: After running dua as root I got a better view of what takes up space. /root/.cache takes up 4.8GB and /var/lib/snapd/cache take up 1.2GB. What are those folders?

Neither clean nor autoclean remove anything stored in /usr, so their lack of progress seems like expected behavior. Similarly, snaps aren't stored in /usr. — user535733, Sep 26 '19 at 08:34
The state in the pictures is after trying out the things I mentioned and thus they actually helped. — Iason Manolas, Sep 26 '19 at 08:35
Run Disk Usage Analyzer and see what's taking up your space in /usr. DUA is included with Ubuntu. Do a desktop search for it (Windows key) — user535733, Sep 26 '19 at 08:37
I already did that. One of the images attached are actually from dua. — Iason Manolas, Sep 26 '19 at 08:39
DUA will tell you what is taking up all your space. So what is taking up all your space? — user535733, Sep 26 '19 at 08:41
There are plenty of questions on here about deleting the contents of cache and .cache folders. If you delete it shouldn't give you any serious issues. I suggest you search for "delete .cache" on here and make your own mind up. If you browse the folders it should give you an idea about what might be affected. — PonJar, Sep 26 '19 at 11:21
Yes I guess my problem was that due to permission restrictions I did not get a full view of my system.. — Iason Manolas, Sep 26 '19 at 11:33

I was only getting a partial view from the disk usage analyser and what helped me get a full view was to execute it as root using:

sudo baobab

In my case I deleted /root/.cache (after login as superuser) and the snapd cache under /var/lib/snapd/cache which in total accounted for 7GB

sudo -H baobab Never ever start graphically programs only with sudo. it can break ownership from important files in your $HOME. – nobody Sep 26 '19 at 11:54
I didn't know that.. But does baobab even change ownership, I thought it's meant for inspecting purposes. – Iason Manolas Sep 26 '19 at 12:06
