When I run
apt-get install mysql-server I get the following error:
Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/m/mysql-dfsg-5.1/mysql-server_5.1.41-3ubuntu12.6_all.deb 404 Not Found [IP: 18.104.22.168 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
This is a rather old server, so I'm thinking maybe something is out of date? However, I have no idea how to fix it. I'd appreciate any help I could get!
