I've just upgraded from Ubuntu 12.04 to 14.04 and my phpmyadmin installation just vanished (I guess I did something wrong!). I've tried to reinstall it, but got this:
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:
phpmyadmin : Depends: php but it is not installable
Depends: php-cli but it is not installable

Any suggestion would be greatly appreciated.
