This is more of a curiosity question as I try to get a better understanding of apt and package management.
I'm seeing that in my /etc/apt/
and /etc/apt/sources.list.d/
folders I have very or sometimes identical files which have the extension of sources.list
, sources.list.distUpgrade
, sources.list.save
, and so on.
What's the point of these duplicate or similar files?
sources.list
and sources.list.save
in /etc/apt/
seem to be identical but sources.list.distUpgrade
shows quantal instead of raring for most stuff (I probably first installed quantal).
On the other hand, in the case of google-talkplugin.list
and google-talkplugin.listUpgrade
in /etc/apt/sources.list.d/
the content of the files seems to be completely identical.
Didn't find much in Google searches. I reviewed the sources.list manpage but it didn't talk much about it.
Also noticed this article where a bug related to the extensions was noted for 10.10
