Can't update or upgrade packages

[daniel.meechan.1u]

Hi, I'm running 12.04.5 and when I do apt-get update, I get this error:


W: Failed to fetch http://ftp.osuosl.org/pub/mariadb/repo/5.5/ubuntu/dists/precise/Release Unable to find expected entry 'deb-src/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.


And when I do apt-get upgrade, I get this:

Reading package lists... Done

W: You may want to run apt-get update to correct these problems
I've tried clean and autoremove but to no avail. Any ideas?

'Clean' removes packages. It does not fix your sources.list file.
'Autoremove' removes packages. It does not fix your sources.list file.

One way to fix it:
Open Software Center -> Software Sources.
Uncheck the duplicate entries.

Another way to fix it:
Edit the raw files (in /etc/apt/sources.list or /etc/apt/sources.list.d/ ) in your favorite text editor, using sudo.

[ajgreeny]

Start by running command
sudo rm /var/lib/apt/lists/*which may clear up one of the problems, then run
sudo apt-get update again to refresh the lists just removed.

If there is still a problem lets have a look at the output of
cat /etc/apt/sources.list
ls /etc/apt/sources.list.dto find any duplicate lines in that file, and what extra repos you have enabled.

I have however just noticed a problem in your shown output from the upgrade command with the repeated lines

W: Duplicate sources.list entry http://ftp.osuosl.org/pub/mariadb/repo/5.5/ubuntu/ precise/main amd64 Packages (/var/lib/apt/lists/ftp.osuosl.org_pub_mariadb_repo_5.5_ubuntu_dists_p recise_main_binary-amd64_Packages)where a space seems to have crept in to the word precise somehow. I note that you did not use code tags for that output and it is possible that a straight copy into quote tags has caused the space.

It is always worth adding code tags to terminal output that you copy to forum posts. See my signature for a "How-to"
