Messages that disk is full even tho there's over 70Gb free space
If I try to install a program via rpm-ostree or download files / copy files with my file manager, I always get a notification that there is no more disk space. But if I look at the disk space myself, e.g. with df, the disks program, etc, it always says that I have over 70GB free disk space on my partition. Where is the problem? I can't do a proper system update because of that message, so what should I do?
