Current mercurial version 1.5.2 from unstable doesn't work with python 2.6. It tells:
> hg pull pulling from https://azhavnerchik:***@<url> searching for changes abort: authorization failed This started happening after I updated python package which made python2.6 the default python interpretor. After I installed python2.5 back and made /usr/bin/python link to /usr/bin/python2.5 right hg's behaviour got back. I tried to use latest mercurial from official site (v1.5.4) and seems it works well. So could you update mercurials version in unstable? I use amd64 arch.
