I've been facing this problem with installing some other packages too. Inside terminal I type: sudo apt-get install mysql-server and I get the following: Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: libhtml-template-perl mysql-server-5.1 mysql-server-core-5.1 Suggested packages: libipc-sharedcache-perl tinyca mailx The following NEW packages will be installed: libhtml-template-perl mysql-server mysql-server-5.1 mysql-server-core-5.1 0 upgraded, 4 newly installed, 0 to remove and 0 not upgraded.

On trying to install with synaptic package manager, I get the following screenshot I am bascially trying to setup LAMP. Any help/suggestion would be great. Thanks.
