Ok, I see. The problem is as follows:

Upgrades from -1 are not supported, -1 were experimental packages.

So please:
	- purge all texlive packages
	- reinstall the -2 packages

I thought about this and included a check for upgrades with a warning:
      echo "Upgrade from experimental versions are not supported!" >&2
      echo "Please purge all texlive packages before installation." >&2
The bug here is that the snippet of preinst code didn't end up in
texlive-doc-base, but only in texlive-common. Reason behind: Before
texlive-doc-base was at the bottom of the dependency tree. For -2 I
created texlive-common and moved the code there, which was a bug, as
there was never a version texlive-common 2005-2.

Next version will have the preinst code for upgrade in all packages.

Thanks for insisting. And yes, purging all the texlive packages is the
best idea, as some link canged to files and other way round from the
experimantal packages to the unstable ones.

Best wishes

Norbert
