Issues installing MySQL server on Ubuntu 13.04 I'm currently trying to install a MySQL server on my Ubuntu 13.04 machine. The problem is, when I try to install it, I get error messages indicating that not all packages could be downloaded. When I run sudo apt-get install mysql-server, and after hanging for a while at reading headers, the console reads as follows:

I've tried the suggested fix or running apt-get update and such, I've made sure I have no connections blocked, I've restarted, uninstalled, reinstalled, etc, all to no avail. I've been searching the web all day for solutions I haven't yet tried, but most people with this issue are running an older version of Ubuntu. Suggestions?
Assuming this isn't an Internet connection issue ("Connection failed" is a needlessly obscure message), then this looks like a problem with the particular Ubuntu mirrors your system is trying to use, rather than something specific to MySQL.

The answer posted on What to try when apt-get install xxx Results in Connection Failed seems like it should get you pointed in the correct direction to resolve this.

It's also possible that sudo apt-get update might fix your problem now, even if it didn't fix your problem before, since some time has passed.  I'm speculating, but it could be that if the information fetched by the update operation causes your system behave differently when it's trying to fetch the files you're needing to install, that might also resolve the problem.
