How to clean-up a bad wicd install?

[seantm]

Hi folks --- I'm having a very rough time with a wicd upgrade. I've been using it with no problems for 6 months. that was version 1.40 I believe. I was prompted to upgrade it through the upgrade manager tonight. BIG mistake! The install seemed to never take --seem to corrupt or something and then nothing was working. Ended up connecting with standard network tools on a wired connection. I've browsed forums everyone says uninstall it then --optionally-- try reinstalling it. But I'm unable to even uninstall or get rid of it. I've tried cmd line, synaptic mang. even booting to recovery mode and using the "repair dpkg" option. Nada; -I keep the same error message listed below..

Anyone know how i can really clean this thing out of my system -(Hardy 8.04)?

Thanks in advance!

See the thread on fixing it here: http://wicd.sourceforge.net/punbb/viewtopic.php?pid=812

There's nothing wrong with 1.5.3, its the uninstall script for 1.4.2 that's no good.

Hi, I've read the link from the post above mine, and I'm still unclear on one point. During the upgrade process, will choosing not to keep any of the previous scripts avoid this whole problem? It seems that removing the wicd.prerm file worked for multiple posters, but is that necessary?

I ran into this problem last night and had to revert back to the previous version of wicd to get back online.

Thanks for any help!

It may still work if you choose not to. You can also work around the problem by replacing the /etc/init.d/wicd that comes with 1.4.2 with the 1.5.3 version before installing (or after installing it fails, doesn't really matter). Here's the 1.5.3 version

Hey imdano, thanks for the quick response.

I tried it using this technique - I first replaced the /etc/init.d/wicd file with your text, then removed the wicd.prerm file, and finally chose to upgrade through the upgrade manager.

Then, after attempting to run the new version of wicd using the command 'wicd-client' in the terminal, a bunch of crap came out:


:/var/lib/dpkg/info$ wicd-client
Loading...
Attempting to connect tray to daemon...
Success.

What am i missing here? Thanks!

Does anybody have any advice? Thanks!

It looks like the wrong version of the wicd daemon is running, or maybe you need a dbus restart. Try running this
sudo /etc/init.d/wicd stop
sudo /etc/init.d/dbus restartThen try opening the GUI. If it still doesn't work, run
ps -ef | grep wicdKill all the processes that show up there, then run
sudo wicd -foeAnd post any error messages you see.
