I've searched for this in this forum using several different keywords, but didn't see an existing thread.
'm currently using Mint 13 Maya/Mate 64. Starting yesterday, I've been having problems running Update Manager. Here is the error message I get:
Could not download all repository indexes
The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.
and here is the explanation beneath the error message:
Failed to fetch http://dl.google.com/linux/deb/dists/stable/Release Unable to find expected entry 'non-free/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)
Some index files failed to download. They have been ignored, or old ones used instead.
I've run Update Manager anyway, with the updates it was able to access, but I'm having a couple of small glitches right now and the available updates didn't fix them. I tried restarting my computer and running Update Manager again this morning, but I got the same error message and explanation. Could anyone advise me how to rectify this problem so I can run a full update? If not, I'll give details of my glitches so I can see if I can fix them without updating.
