I'm running Ubuntu 15.04 (x64, i7, etc.). Everything has been working perfectly for a long time. However, this morning I was watching some videos online (YouTube) when Firefox crashed. I tried running it again, but it would crash within seconds of opening, over and over.
After this I started receiving crash reports from Ubuntu itself. I tried submitting them and then after several I finally shut down the system. Upon booting again, Firefox still would not work and I kept receiving errors in Ubuntu. I figured software might be out of date so I tried performing an update.
Sure enough there were several packages that needed to be updated. However, the update failed. Now, long story short... I get the following message no matter what I try to do with apt-get.
Reading package lists... Error! E: Problem parsing Provides line E: Error occurred while processing libfsoframework-dev (NewVersion2) E: Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_vivid_universe_binary-i386_Packages E: The package lists or status file could not be parsed or opened.
Does anyone know what is going on here? Keep in mind that I've done updates countless times in the past and everything has been fine. I haven't changed anything recently and definitely nothing at the moment this all went south on me.
Thanks for your help!
Edit 1 I performed the following.
sudo rm /var/lib/apt/lists/* -vf sudo apt-get update
Upon running the update command in apt-get, I received the following error.
Err http://us.archive.ubuntu.com vivid/universe amd64 Packages 404 Not Found [IP: 22.214.171.124 80] Fetched 31.3 MB in 1min 4s (484 kB/s) W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/vivid/universe/binary-amd64/Packages 404 Not Found [IP: 126.96.36.199 80] E: Some index files failed to download. They have been ignored, or old ones used instead.
I've also unselected all "Other" software sources. However, this Ubuntu source not being available seems to be causing me a lot of problems.
