"mysql-server-5.1 but it is not going to be installed" errorPosted in Linux/Unix/BSD -
This post looks at the error message "mysql-server : Depends: mysql-server-5.1 but it is not going to be installed" when attempting to install MySQL on a fresh install of Debian 6, when Debian 7 is the current up to date distro.
I needed to test something with MySQL on Debian 6 in a test environment (which I can them implement later on some production servers), so downloaded the 1st CD ISO only and installed it into a VMWare Virtual Machine.
When I went to install MySQL, I got this error message:
$ apt-get install mysql-server Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: mysql-server : Depends: mysql-server-5.1 but it is not going to be installed E: Broken packages
It would appear that Debian 6 now only gets security updates and you need to fix/adjust the sources list to be able to install new software.
Edit the /etc/apt/sources.list file and add the following line
deb http://ftp.us.debian.org/debian/ squeeze main
$ apt-get update
and you should be able to install software. I was personally then able to install MySQL and run my tests on this older OS installation.
