When I'm upgrading, get this error and can't install anything else
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies: krb5-multidev : Depends: libkrb5-3 (= 1.10+dfsg~beta1-2ubuntu0.2) but 1.10+dfsg~beta1-2ubuntu0.3 is installed Depends: libk5crypto3 (= 1.10+dfsg~beta1-2ubuntu0.2) but 1.10+dfsg~beta1-2ubuntu0.3 is installed Depends: libgssapi-krb5-2 (= 1.10+dfsg~beta1-2ubuntu0.2) but 1.10+dfsg~beta1-2ubuntu0.3 is installed Depends: libgssrpc4 (= 1.10+dfsg~beta1-2ubuntu0.2) but 1.10+dfsg~beta1-2ubuntu0.3 is installed Depends: libkadm5srv-mit8 (= 1.10+dfsg~beta1-2ubuntu0.2) but 1.10+dfsg~beta1-2ubuntu0.3 is installed Depends: libkadm5clnt-mit8 (= 1.10+dfsg~beta1-2ubuntu0.2) but 1.10+dfsg~beta1-2ubuntu0.3 is installed
E: Unmet dependencies. Try using -f.I tried to run apt-get install -f but I still get the unmet dependencies error.
this is the apt-cache policy output :

A security update for Kerberos packages was issued on July 31, 2012, to fix a security vulnerability. This bumped the Ubuntu version numbers from ubuntu0.2 to ubuntu0.3.
It's possible (but rare) that for a while, the libkrb5-dev/krb5-multidev packages were not updated, and thus had the old dependencies of ubuntu0.2 which was causing your problem.
In any case, it appears this has now been fixed:
$ apt-cache show libkrb5-dev | grep Depends Depends: krb5-multidev (= 1.10+dfsg~beta1-2ubuntu0.3)
$ apt-cache show krb5-multidev | grep Depends Depends: libkrb5-3 (= 1.10+dfsg~beta1-2ubuntu0.3), libk5crypto3 (= 1.10+dfsg~beta1-2ubuntu0.3), libgssapi-krb5-2 (= 1.10+dfsg~beta1-2ubuntu0.3), libgssrpc4 (= 1.10+dfsg~beta1-2ubuntu0.3), libkadm5srv-mit8 (= 1.10+dfsg~beta1-2ubuntu0.3), libkadm5clnt-mit8 (= 1.10+dfsg~beta1-2ubuntu0.3), comerr-dev
Please try a sudo apt-get update && sudo apt-get -f install to try to fix this. If it it doesn't, just remove the libkrb5-dev package. From a simulated removal on my dev system, it appears that the CUPS and QT dev packages may also be removed (libqt3-mt-dev, libcups2-dev). And then install libkrb5-dev again.
I would suggest attempting to remove the troublesome package before upgrading.
First, make sure removing krb5-multidev won't remove anything that appears to be vital.
sudo apt-get remove krb5-multidev --simulateReview the packages under "The following packages will be REMOVED:". If you're not sure whether they are important, feel free to post the list here for us to look over for you.
Assuming nothing looks vital, go ahead and remove krb5-multidev:
sudo apt-get remove krb5-multidevThen attempt the upgrade again. Once you've upgraded, you can reinstall krb5-multidev.
NOTE: There are probably more elegant methods to solve this problem. This is just an attempt to work around the error and get the upgrade done.
2How I fixed it:
I went to the Synaptic package manager in order to fix the broken package. Click on Edit → Fix Broken packages.
