I'm having some difficulties exactly understanding how the the whole update thing work in Ubuntu and good practice for installing software.
I understand I have a
/etc/apt/sources.list file where all my repositories are listed, and that these repositories are queried when I use
apt-get update - to later be used with e.g.
apt-get upgrade. This makes perfect sense and I recently installed
spotify by adding
deb http://repository.spotify.com stable non-free to this "sources" list.
But then I got confused...
When I went to download Google Chrome I merely had to download and grab a
.deb file, and Chrome installed with no problem... but I don't see any new entry in
So how does
apt-get update know where to query concerning Chrome updates? Has it somehow been added to one of the already listed repositories in the sources file?
I would like all my installed software to be encompassed by the update function.
