Apt Dependency Deadlock

Quantumstate · 04-22-2006, 05:49 PM

Ugh, trying to install ffmpeg, and something's gone terrible wrong with apt.

I started out with testing in my sources.lst, but when the problem, commented that out and left only Sarge. No change.

Code:

# apt-get install ffmpeg
Reading package lists... Done
Building dependency tree... Done
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  ffmpeg: Depends: libavutilcvs49 (>= 3:20060323) but it is not going to be installed
  libavcodeccvs51: Depends: libavutilcvs49 (>= 3:20060323) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

The 'force' flag seems to be ineffective.

Any ideas?

The "-f" flag does not mean "force". It actually stands for "fix broken" and can best be summed up as "ignore what I said to do, if it will fix things". So, I suggest running "apt-get remove libavutil49" without the "-f", and see if that improves things at all.

Also, you could try using dselect - it may make some suggestions (though it may also get you more goofed up).

Try removing all of them at once

apt-get -f remove libavutil49 libavutilcvs49 ffmpeg

Then install ffmpeg, has worked for me before, just depends on the way their packaged if it works for you. libavutilcvs49 should have been marked as incompatabile with libavutil49.

Do an update before you do this.

Thanks, but I'd tried this in several permutations:

Code:

# apt-get remove libavutil49
Reading package lists... Done
Building dependency tree... Done

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

... and I've tried installing and removing every other package mentioned in these messages, but it's stuck.

Code:

# apt-get -f remove libavutil49 libavutilcvs49 ffmpeg

Package libavutilcvs49 is not installed, so not removed

Have done several updates after including only Sarge in the sources.

A little afraid of dselect.

Add libavcodeccvs51 to the line, and any others that appear.

apt-get -f remove libavutil49 libavutilcvs49 ffmpeg libavcodeccvs51

Oh man, thank you. I lack to had a heart attack when it worked!

How did you know to do this? Do I dare reinstall ffmpeg?

leonscape · 04-22-2006, 08:13 PM

Yes try installing ffmpeg.

I learned this just by figuring it out when I needed it myself. You have to learn these things when you use 3rd Party Respositories.

Are you using ftp://ftp.nerim.net/debian-marillat/ this is where I got ffmpeg and mplayer etc, a good site.

Yes, thanks. Got AVView compiled now (Gatos), but it crashes on setup. Suspect it's too old for current ffmpeg,as it recommends the ancient 0.4.8 (which won't even compile for me).

But, I'm having second thoughts about using my built-in ATI Rage Mobility M3 for video capture. Although it is represented to work, I'd like to capture HDTV, rather than SVideo.

Are there any cardbus cards which are known to work for HDTV? I realize that it's a tall order.
