16.04 - Not all installed packages are listed in the Ubuntu Software app - Ask Ubuntu


this on 16.04 lts.

my understanding ubuntu software (formerly software center) should list installed packages on system. however, mine doesn't. example, i've installed google chrome, virtualbox, , dropbox. chrome listed in ubuntu software, 2 others aren't.

why this? bug or intended behavior?

to list of packages installed locally in terminal:

dpkg --get-selections | grep -v deinstall

(the -v tag "inverts" grep return non-matching lines)

to list of specific package installed:

dpkg --get-selections | grep postgres

alternatively, use

dpkg -l

ubuntu 14.04 , above

apt list --installed
