package version numbers
 

There are several packages that, when I try to upgrade them, aptitude
tells me that doing so would break many other packages. For these other
packages aptitude says:

Depends: libglib1.2 (>= 1.2.0) but it is not installable

However, 'apt-cache policy libglib1.2' shows:

libglib1.2:
Installed: 1.2.10-17
Candidate: 1.2.10-17
Version table:
*** 1.2.10-17 0
100 /var/lib/dpkg/status

Isn't 1.2.10-17 greater than 1.2.0?

Could someone please explain this to me?

It is in stable as well. Don't you have stable in your sources.list?

Package libglib1.2 appears to have been replaced by libglib1.2ldbl, and
it shouldn't be depended upon by any package.

The only exception seems to be the package xmovie, and I'd say it's a
bug. So don't install xmovie for now.

What this means is that the solution to your dependencies that
aptitude calculated didn't leave libglib1.2 on your system. Probably
the message should say "it is not going to be installed", not
"it is not installable".

In order to give you a more specific answer I'd need to know what you
were trying to upgrade and ideally see all the output from aptitude.

After reading Carlos Sousa's reply I was able to figure out a little
more what's happening. I get hesitant when aptitude tells me it wants to
remove programs that I use.

Anyway, I see that xmms is replaced by xmms2 and that qiv will upgrade
with libglib1.2ldbl. My only remaining problem is multi-gnome-terminal,
which is not in lenny. Why not? There are several reasons I prefer
multi-gnome-terminal to gnome-terminal:

1) Though the gnome-terminal help page mentions it, the actual
preference setting gives me no way to stop the cursor from blinking.
I can't stand a blinking cursor!

2) My prefered font, the one I've been using for years, neep, is not in
the list of available fonts. It's in the xfonts-jmk package.

3) Not really a problem, but a convenience. multi-gnome-terminal gives
me the option to open a tab as root.

4) multi-gnome-terminal has many other options that I've become
accustomed to that are missing from gnome-terminal.

If someone could suggest how to solve those problems, I think I'll be ok.

It apparently died upstream, and had to be removed from Debian
due to dependency on incompatible (newer) Gnome libs.

If you really want to use old packages on modern debian distributions,
you can manually edit /var/lib/dpkg/status to correct dependencies.

In this case this means

cp -pai /var/lib/dpkg/status /var/lib/dpkg/status.SAVED

$EDITOR /var/lib/dpkg/status

search for libglib1.2 in the "Depends: " lines and change it to
libglib1.2 | libglib1.2ldbl

(you can also do such kind of things after a manual download of a
$PACKAGE.deb and a dpkg --force-depends -i $PACKAGE.deb )

Note that you can use archive.debian.org and/or snapshot.debian.net in
your /etc/apt/sources.list (and perhaps also adjust /etc/apt/preferences
according to man 5 apt_preferences)

Note also that that these operations are UNSUPPORTED. I do them
routinely and they work fine for me (infact, my reasons to use debian
are these kinds of extreme configurability), but: NO WARRANTY.
