Some days I like helping -proposed updates to go faster to -updates, I do that by testing -proposed changes, I borrow some of them from: http://people.canonical.com/~ubuntu-archive/pending-sru.html
I always do it in a pbuilder environment or when the changes requires lots of packages I use a virtualbox machine, when using pbuilder I add the -proposed repositories and do the tests, yesterday I was testing #1073574 and found a weird error:
root@sup:/# apt-get install havp 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: havp : Depends: libclamav6 (>= 0.97.6+dfsg) but 0.97.3+ dfsg-2.1ubuntu1 is to be installed E: Unable to correct problems, you have held broken packages.
It was a simple change, it should had to work but it wasn’t.., so I posted it, and ScottK help me to remember that -updates wasn’t enable, so I add them and it worked =), I hadn’t had this problem because with some packages the -update repository isn’t needed, however I’ll remember to do it next time it fails to install.
