SOLUTION: Firefox Fails When Upgrading After Using Mozilla PPA

This is a quick fix for a problem I had when upgrading to Ubuntu 10.04, after having used the Mozilla PPA.

The Firefox upgrade failed during the distribution upgrade process (from 9.10 to 10.04). I was told to run `dpkg -a –configure`, and the same error occurred again (it’s in bold).

$ sudo dpkg -a --configure
Setting up firefox (3.6.3+nobinonly-0ubuntu4) ...

A quick web search brought up a bug report, and I was able to figure out this fix with the help of one of the comments:

Update: Fixed.My original solution was only temporary, and had to be repeated for each Firefox update (all the way through every update with 10.04, 10.10, now 11.04…). I’ve found the root of the problem now, by comparing local dpkg diversions for Firefox on my affected machines against an unaffected clean Ubuntu install.

On my laptop:

$ sudo dpkg-divert --list | grep firefox
local diversion of /usr/bin/firefox to /usr/bin/firefox.ubuntu
local diversion of /usr/bin/mozilla-firefox to /usr/bin/mozilla-firefox.ubuntu

The clean Ubuntu install returned no results for the above command. (Also, note that in the full output for dpkg-divert –list, those were the only local diversion — another hint that they were from the PPA upgrade rather than Ubuntu itself.)

So, I ran the following commands to remove the diversions:
$ sudo dpkg-divert --remove /usr/bin/mozilla-firefox
$ sudo dpkg-divert --remove /usr/bin/firefox

Then, the most recent Firefox upgrades worked without a hitch on both of my affected machines. Finally fixed… *fingers crossed*

Updated: This isn’t a complete fix, as the problem reoccurs every time Firefox is updated. If someone knows how to fix this for good, let me know…

$ sudo rm /usr/bin/firefox
$ cd /usr/bin
$ sudo ln -s ../lib/firefox-<your-current-version>/firefox.sh firefox
$ sudo chmod 0777 firefox
$ sudo apt-get -f install

The symlink for /usr/bin/firefox had been pointing to /usr/bin/firefox-3.5, which no longer existed, so the commands above (1) remove the dead-end link; (2) add the proper link (YMMV depending on which version of Firefox you are upgrading to); (3) resume the upgrade process.

Hope that helps!

SOLUTION: Extract .exe archive with 7z in Ubunu 9.04, fix “Unsupported Method” error

Just posting a quick fix to a problem I had with using 7z to extract an archive. I could list the contents of the archive, but any attempts to extract gave an “Unsupported Method” error. Dan Jacobson posted a solution to the debian bug tracking system, which is to install the package p7zip-rar.

In Ubuntu 9.04, I ran:
sudo apt-get install p7zip-rar

Now, I can extract the contents of my file with 7z as follows:
7z e TekSavvyAM.exe

Solution: Amarok Won’t Play Anything After An Upgrade To Ubuntu 9.04

I was happy to discover earlier today that Ubuntu 9.04 includes Amarok 2. But once I figured out how to queue up some music (which took a little time), I realized that nothing would play.

This was the standard output when I ran it from the command line:

The “QString::arg: Argument missing: Amarok – No track playing., 0:00” seemed to be the problem. I found the solution from Xavier Merino:

sudo apt-get install phonon-backend-xine

I restarted Amarok and now it works fine.

Update: People are reporting mixed results in the comments. This fix doesn’t work for everyone. Let me know if you become aware of a better solution and I’ll update here.

Another suggestion is sudo apt-get install libxine1-ffmpeg

sox soxio: Failed reading : unknown file type

I began receiving this error in Ubuntu (after upgrading to Hardy 8.04 I think) whenever I tried to use the sox or play commands. Turns out the solution is pretty simple, sox had just lost its available format libraries.

sudo apt-get install libsox-fmt-all
