dapper -> edgy upgrade breaks on python-clearsilver and python-pythoncard packages

[randomjunk]

Binary package hint: python-clearsilver

The apt-get dist-upgrade command throws out the following. It seems to be conflicting with some other version of itself from somewhere:

I'm getting the same error for python-clearsilver when upgrading to edgy Xubuntu (using dist-upgrade).

[Michael Hackett (at217)]

My workaround was simply to remove python-clearsilver, as I suspect the python2.4-clearsilver package (which has the same version number) will do the trick for whatever is depending on it. I guess I'll find out if that's the case soon.

Is this maybe an old package that should be removed? It seems that usually packages named like this are empty packages that depend on the latest more-specific version of the package, to make upgrading easier. Does this one actually contain all the same files as the python2.4-clearsilver package?

[John Vivirito (gnomefreak)]

Is this still a problem for either of you?

[Taylor Mitchell (tmitchell)]

Just ran into this bug today. Backing out python-clearsilver will require me to remove trac also so I'm not inclined to do that.

[Michael Hackett (at217)]

John,

As far as I can tell, nothing has changed. I did an update and try to install python-clearsilver again and got the same error.

Having never packaged anything, I'm not sure about this, but it seems from other packages are organized that the python-clearsilver package should be an empty archive with a dependency on python2.4-clearsilver (or whatever is the current version).

Instead, it contains the same set of files as the python2.4-clearsilver archive, but appears to contain a newer version of the package (0.10.3-2 vs. 0.9.13-3.2). I know nothing about this package itself (it was installed as a dependcy of something else), so I don't know if there's a reason to keep the old version, but if not, I'd suggest repackaging the current version as python2.4-clearsilver and making the package with no version number strictly a dependent on that real package. Please correct me if I've got this stuff wrong, as I'd like to get more involved once I understand the system a little better.

python-clearsilver need to conflicts/replaces python2.4-clearsilver. Now it only conflicts/replaces python2.3-clearsilver.

I was two releases behind, so I did an upgrade from dapper to edgy, which appeared to go flawlessly. Then I did an upgrade from edgy to feisty, which broke as listed above, except that I only have python-pythoncard installed (not python-clearsilver) and the target version is 0.8.1-3ubuntu1, not 0.8.1-3ubuntu1.

I can provide my full logs upon request. Does anyone have a solution for this yet?

[Bobby (bobbymartin2)]

Er, forget the nonsensical comment about the target version.

I meant to say the installed version of python-pythoncard was python-pythoncard_0.8.1-8.1_all.deb, not python-pythoncard_0.8.1-7_all.deb.

I had such a similar issue when upgrading from Edgy to Feisty. After the upgrade, a "sudo apt-get dist-upgrade" would look like this:

A simple "sudo apt-get remove python2.4-clearsilver" didn't fix the problem, as I'd expect. I had to remove both python2.4-clearsilver and python-clearsilver, which in turn removed trac, as well. So, I fixed the problem like this:

[Artti (artti)]

Forget about last one. I missed the "trac" part.
