Package: texlive
Severity: important
Running aptitude install texlive, (not apt-get) results in errors
that keep one from installing the complete package. I suspect it's a
problem with feynmf and prosper. Here's the message aptitude gives me:
The following packages have unmet dependencies:
feynmf: Depends: texlive-font-utils but it is not installable or
tetex-bin but it is not installable
Depends: texlive-extra-utils but it is not installable or
tetex-bin but it is not installable
prosper: Depends: tetex-extra but it is not installable or
texlive-pstricks but it is not installable
Resolving dependencies...
The following actions will resolve these dependencies:
Install the following packages:
texlive-generic-recommended [2005.dfsg.2-4 (testing)]
texlive-pstricks [2005.dfsg.2-3 (testing)]
Keep the following packages at their current version:
feynmf [Not Installed]
Leave the following dependencies unresolved:
texlive-metapost recommends feynmf
Score is -279
Accept this solution? [Y/n/q/?]
Since texlive is a large metapackage, it is very useful to be
able to use aptitude with it well; because that way if one
wants to remove the metapackage and all its dependencies, aptitude
can do that.

Hi Joshua!
I am closing this bug as it is not a "bug" but a "feature" of aptitude,
lets put it this way. The point is that aptitude tries to find a smart
solution. "smart" in this case seems to be not really smart, but that's
the way it works. Here is a detailed explanation:

Ok, it is not about feynmf, nor about texlive, it is about a bug (?) in
aptitude:
feynmf prefers texlive over tetex
prosper prefers tetex over texlive
(in the sense of order of the dependencies).
Now prosper asks for
tetex-extra | texlive-pstricks
but texlive does not pull in texlive-pstricks automatically. So what
happens is that aptitude considers the solution of installing
texlive-pstricks as less good than the solution to leave fenymf and
prosper uninstalled.
If you select two time `n' aptitude will propose the 'correct' solution:
$ aptitude install texlive

So selecting two times n and then yes you will have texlive installed as
you wanted.

BROATS
A pair of trousers with a career behind them. Broats are most commonly
seen on elderly retired army officers. Originally the brats were part
of their best suit back in the thirties; then in the fifties they were
demounted and used for gardening. Recently pensions not being what
they were, the broats have been called out of retirement and
reinstated as part of the best suit again.
