Running 11.04 and I downgraded down to php5.2 due to some needs. I don't remember how. I'd like to get back up to 5.3 now. I'm trying to use apt-get upgrade but I get the following messages:
$ sudo apt-get -f install
Reading package lists... Done

Reading state information... Done
Correcting dependencies... failed.
The following packages have unmet dependencies:
krb5-multidev : Depends: libkrb5-3 (= 1.8.3+dfsg-5ubuntu2.2) but 1.9.1+dfsg-1ubuntu2.2 is installed

Depends: libkrb5support0 (= 1.9.1+dfsg-1ubuntu2.2) but 1.8.3+dfsg-5ubuntu2.2 is installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies
I'm not having any luck finding any leads on how to fix.
Let me know if I should provide more information.
