The Volume "Filesystem Root" Has Only 533.9 Mb Disk Space Remaining

Question

I have run into this problem two days ago. The OS warns me that root has limited
disk space; however this should not be the case since I have 3 separate logical partitions for Ubuntu. Also it allows me to click the button examine, but I am not able to locate the problem that way? What can I do and what is the remedy? Inform me if further information is required.

Thanks for your assistance

Can I somehow include /usr directory in another mount point or the partition for the home folder without risking losing my data?

The culprit seems to be the /usr directory. The problem occurred after a full TexLive LaTeX installation. The output of lsblk is as follows:

You can use the "Disk Usage Analyser" to see what is using all of your drive space.

Open "Disk Usage Analyser" by searching for it in the Dash.
Click on your root (/) drive.
Wait for the graph at the right to stop displaying loading dots (it may take a while).
You can now review which files are taking up the most space (You can just close the 'Permission denied' error if it appears).
Hover your mouse over a sector to get the name of that folder and its size.

To delete the largest files/folders

After performing the above steps and with the file path to a larger file/folder which you want to delete, you can do the following:

Only if the file is in your Home directory, you could just move it to an external hard drive (or delete it altogether if it's unimportant)
If the file is not in your Home folder, you can take a guess at which package it belongs to and try apt-get uninstall to remove that package (if you don't need it)
Anything else, please edit your question with the path to the file/folder which you'd like to delete. You should not randomly delete files which are not in your Home folder.
