Hullo there,

Does anyone use trac on debian?

I've just upgraded a server from etch to lenny.  It had a backport version of trac 0.11.1-2~bpo40+1.

The lenny version is 0.11.1-2

However, the backports package refuses to uninstall to make way for the new version.  Installation errors show:

Preparing to replace trac 0.11.1-2~bpo40+1 (using .../trac_0.11.1-2.1_all.deb) ...

I tried moving /usr/share/pycentral/trac to one side but the same error occurs.

Google is not my friend :-(

Can anyone advise?  I'm not much good with pythony things.

apt-get remove trac apt-get install trac

Done, because the lenny version is "newer" than the bpo version:

brettp@miranda:~$ if ( dpkg --compare-versions 0.11.1-2~bpo40+1 lt 0.11.1-2 ); then echo yes; fi yes brettp@miranda:~$ if ( dpkg --compare-versions 0.11.1-2 gt 0.11.1-2~bpo40+1 ); then echo yes; fi yes brettp@miranda:~$

So, a simple removal and then install should be all it takes.

The problem is that it *won't* remove, - it gives the same errors: Removing trac ...
