I installed Lubuntu yesterday and updated it.
Whenever I run sudo apt-get update and afterwards sudo apt-get install spotify (for example), I get E: Impossible to get package "spotify-client" (roughly translated from my native language).
I have used ubuntu before amongst other distros but this is the first time it happened to me. I had the same error while trying to install filezilla and arandr.
Any idea on this one?
