Ubuntu
pypar2 package

lots of errors when I run pypar2 from command line

Asked by bnsmith001

I may need to download some modules, not sure.
Synaptic tells me that I have pypar2 1.4-6, after I did a re-install through Synaptic.
I'm running Ubuntu 12.04 (Precise), and Ubuntu has installed Python 2.7.3-0ubuntu2.
I also did a re-install on that Python package.

When I try to run it from the Launcher, nothing ever opens.
When I try to run pypar2 from the command line, I get --

Based upon the errors, it appears that Python is not automatically accessing the libraries that it should.

Re-Booting after the installs.

Please advise if there is something else to try, based upon the errors.

I learn more about Linux every time I ask a question. Now I have to learn more about the lsb commands. :)

Sure.

The response --

I suggest you run:

ubuntu-bug pypar2

And report a bug

I did while I was writing the original question.
I removed & reinstalled pypar2 & Python, while I was writing the question.

Re: "pypar2 1.4-6, after I did a re-install" & "re-install on that Python package".

Yep... I tried that.

I figure something in the two imports isn't getting imported, thus the other errors occur.

I've linked this question to the bug report.

GOOD NEWS!

Somehow, my backups filled up the volume where / is.
Some time after I installed pypar2 when I removed it and installed, or when I did one of the reinstalls or at some point...
the volume was very full, and it could only create a 0 length file for ~/.pypar2/prefs.xml .
Before doing the N-th reinstall (when "bugs" had me look at the the prefs.xml file which was 0 bytes long), I did a df and found that there was enough space on the volume holding / ... so I did ANOTHER reinstall.

Pypar2 started up like a champ, and is working very well at the moment.

So now I can continue the rar/par/burn process, trying to get my computer ready to restore my Windows 7 image... which will wipe out my Ubuntu. I'm in the process of backing up ALL data files from both environments. I've already copied all of my Ubuntu files to my Windows ~/Downloads/Ubuntu directory, I have a Win7 image from 05/28 on an external USB, a daily/weekly Win7 backup last made around 7/8/12... when Windows 7 stopped booting. Luckily, I chose to install Ubuntu as Wubi, so I have access to all of my Windows files through /host/* .

Hopefully, I don't run out of DVD-Rs before I run out of data to backup. ;) I'm using /host/User/-user-/* folders, and am using rar/par/md5 utils from my booting Ubuntu partition to backup all of my data.

Remaining Question (important in my situation) -- How do I list all Ubuntu packages that I have installed before I restore the Windows image?

After I get Win 7 back'd up, and the image restored, and Wubi re-installed, I need to start pouring through these backups and determine what files I need to restore. :)

Can you help with this problem?
