I installed Ubuntu Gnome 14.04 a month back. It all worked perfectly but after two days I repeatedly got the notification
File system root low disk space 0 MB left.
I had installed everything correctly, with root space 21 GB. However, I reinstalled Ubuntu to get rid of this, this time with root as 100 GB. It all worked fine for 20 days. But today I started getting the notification again. File system root low disk space- 1 GB left.
I can't find how to resolve this issue. Why is root filling up so fast? Wherever I read, it says 15-20 GB is enough, but even 100GB is apparently not sufficient in my case!
