package squid 2.7.STABLE3-4.1ubuntu1 failed to install/upgrade:

Could you repost the /var/log/dist-upgrade/ contents? It apparently got truncated to 40bytes...

Here is the contents of the entire directory. I tar and gzip'd them.

Hope this helps.

:)

Yeah, those files might have helped :) Just not sure if the archive was gzip'd...

Don't think this is a generic problem. I installed squid on a fresh 8.10, did a do-release-upgrade to Jaunty, and Squid was still working. Of course, that was with only the default configuration.

Looking in your /var/log/dist-upgrade/term.log I see quite a few attempts to access the non-existent path /null. At one occasion it happens right next to your "subprocess post-installation script returned error exit status 1".

Can you find anything in your squid configuration which would explain why the upgrade would want to access /null?

Actually yes, I have the cachedir set to /null so that my squid configuration doesnt cache any of the pages it visits.

Having a non existing cachedir doesn't seem to the entirely proper solution.

The reason this error occurred was because the package manager tried to read the permission of a folder which turned out not to exist. Not entirely sure if this is classify as a bug, considering it is the result of a somewhat faulty configuration.

hmmm I would have to agree with you, there should be a directory /null I dont know why I dont have it there. I apologize. A faulty configuration definitelyw ould be the issue in this case.

Well, since we seem to agree I'll be setting the status of this bug to Invalid.

By the way, if I understand that FAQ entry correctly; since you'r running Squid 2.7 you might not even need a cache_dir entry if you'r not going to do any caching. Anyhow, I'm really no Squid expert, so I will leave the figuring out to you.
