Ookay, so this morning I got message I've only 300 mb free space on root filesystem.So I cleaned everything I could. Now there are 5.2GB available.
But, (i'm novice user) I see that I might have made a mistake when installing Ubuntu. Then i made 40GB space for "/" and 200GB for '/home'. Seems that the 200GB are not used, and the files in '/home' are using root's space. And stuff like vscode and gimpp are using root's space. I've attach photo of 'df -T' output. How do I fix this..? terminal:$ df -T
