My update manager does not find any updates. It does not crash or anything, but no update for my ubuntu, except for the PPAs. At first I thought there really was no update out there, but now it has been more than a month since my last update. What is wrong here?

$ cat /etc/apt/sources.list
deb http://ir.archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse

(I also tried the MainServers, but still nothing.)

You must have the -updates and -security repositories set!

You aren't getting any updates because they go into the precise-updates and precise-security repositories, and you only have the main precise repository in your sources.list!

  • Set up Software Sources this way:

  • Or if you want to manually edit /etc/apt/sources.list, add the following two lines:

    deb http://ir.archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse
    deb http://ir.archive.ubuntu.com/ubuntu/ precise-security main restricted universe multiverse
