Virusboy has the right idea, and after digging around, I can confirm that /usr/share/app-install
is related to software manager. This thread mentions that the folder is related to app-install-data package. Doing a simple check apt-cache search app-install-data
reveals the following:
$ apt-cache search app-install-data
app-install-data - Ubuntu applications (data files)
app-install-data-partner - Application Installer (data files for partner applications/repositories)
And take a closer look at lines 14 and 15
$ apt-cache show app-install-data | nl

a
and I want to make a copy calledb
, I can create a symlink froma
tob
. So I only waste the disk space that requiresa
and not twice the size ofa
. And a additional advantage is that when I change thea
contents, asb
is a symlink, their content will also change.
