But, this is not the largest program that I compiled.
I guess your root filesystem was not that full when you compiled those larger
programs.
So, 20gb of root are full right?
Right.
it is where I have installed all packages from Synaptic? it is /dev/sda1/ and
not where I stome my user's files: /home/USER/ ??? right?
Not only those programs: everything but what is the home folders of the
users.
I dont know what it does.
'sudo apt-get clean' removes the .deb package APT downloaded. You usually do
not need them once the packages were installed. However it may happen that
the package manager has to reinstall a package. Without the .deb, it would
download it again. 'sudo apt-get autoclean' keeps the latest versions of the
packages for that reason.
So, I have no free space in my 20gb partition, can I make it bigger with
LiveCD/USB nad Gparted?
You can. But, as I explained earlier, it is not that easy because your user
data are on an XFS filesystem. That is why I suggested you to first
graphically discover where did the 20GB of space go (and hopefully remove
useless files/packages): the "Disk usage analyzer" in the "System settings"
does just that. Just double click on the root partition to analyze it. You
may discover interesting things.
To start with, /var/cache/apt/archives may contain GB of .deb packages since
you never cleaned them.
