software center won't start

Asked by Steve Lundback

My software center won't start and I've tried several of the fixes suggested on other posts. Please offer further advise.

 Here's what I get when I try to reinstall:

ubi@ubi-Aspire-1410:~$ sudo apt-get -y --reinstall install software-center

This looks like a bug in the Software Center (or perhaps in Python), but let's be sure first. Please do steps 1-4 at https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure. If that does not fix the problem, then please run the following additional command (which you will see is subtly different from the command you ran above):

sudo apt-get -y --purge --reinstall install software-center

If that does not fix the problem, then please post all the text from the Terminal here. At that point, I will probably advise you to report a bug by enabling Apport crash reporting and reproducing the crash to trigger an automatic report, followed by filling in details about what happened. (But I will look at the output you provide and see if I have any other ideas first.)

Before reporting bugs in Ubuntu, you should make sure to read https://help.ubuntu.com/community/ReportingBugs carefully. (So after you provide the information requested above, you may want to do that, as I will most likely advise you to report a bug after I read through the output that you will have provided.)

If/when you do eventually report the bug, you can enable Apport with the procedure at https://wiki.ubuntu.com/Apport#How_to_enable_apport (then triggering the problem again should cause Apport to come up automatically and submit data to Launchpad), and you can link the bug to this question using the "Link existing bug" link here.

The description of changes from the current software-center version (4.0.4) to the version in natty-proposed (4.0.5) doesn't contain anything that looks like it would be a fix for, or otherwise relevant to, this bug, but if you want to see if the version in -proposed works, you could enable the natty-proposed repository using the instructions in https://wiki.ubuntu.com/Testing/EnableProposed. You may want to use pinning to prevent packages besides software-center being upgraded to the version in -proposed, which are generally less stable (because they are still undergoing testing). You will notice that those instructions tell you to use the Software Center to enable this repository, which is obviously not going to work for you, but you can access the Software Sources window from the Synaptic Package Manager, from the Update Manager, or by pressing Alt+F2 and running the command "gksu software-properties-gtk" (without the quotes).

While you are suffering from this problem, if you want a graphical tool for package management, you might considering using the Synaptic Package Manager ("sudo apt-get install synaptic" in the Terminal to install it).

Thanks Eliah!

I tried those step to no avail. However, I was unable to do step 1, changes the source, because I found my Update Manager won't launch either.

I appreciate your detailed instructions as I'm new to the open source environment. I'll be happy to help by reporting bugs.

Step 1 is, in your particular case, not very important, because you're not having a problem downloading the .deb file for software-center--you're just having a problem installing it. Furthermore, the file's signature does check out (the failure happens later, when a post-install script runs), so the problem is not due to corruption of data between you and your regional server.

Therefore, since the above commands did not fix or significantly change the nature of the errors, I'd say you should go ahead and, after reading https://help.ubuntu.com/community/ReportingBugs carefully, report this as a bug. Important information about how to do that is in my previous post (post #1 as numbered at https://answers.launchpad.net/ubuntu/+source/software-center/+question/172928).

We can also investigate the problem with the Update Manager. If it turns out to be the same as the problem with the Software Center, then you can edit your bug report to reflect that. (If you prefer, you can wait to file the bug report until you've tried this, but that's not necessary.)

What happens when you run this command in the Terminal?

software-center

And what happens when you run this command in the Terminal? (If the Software Center is running after the previous command, please make sure to close it.)

update-manager

Please also try them with gksu (make sure neither the Software Center nor the Update Manager is running, at the time that you run each command), and report the results here.

gksu software-center
gksu update-manager

I am also curious as to whether or not you are getting the same problem with software-properties-gtk:

gksu software-properties-gtk

Finally, you originally posted about this problem in https://answers.launchpad.net/ubuntu/+source/software-center/+question/172573. Was there any specific reason, besides what you've said there and here, why you think you were experiencing exactly the same problem as Paritosh Bapat (who posted that question)?

Here's what I got when running the commands. I got a pop-up window with the last two that listed the sources.

As for the final question, I initially looked for a solution by going to the Ubuntu homepage, clicking the technical answer section, then searched for a similar problem. This is the first time I've sought support for Ubuntu, and have been using the OS for only a few weeks.

Just to let you know I'm going to forgo the bug reporting due to privacy concerns.

Thanks for your help,

Since it looks like this is a new bug (a search for "ImportError: cannot import name MissingErrorHandlerException" doesn't turn up much), it seems unlikely that it will be resolved if you do not submit a bug report. (I'm leaving this question Open with the hope that someone else will have an idea. It will expire automatically, but you can always reopen it.)

I reinstalled Ubuntu and haven't had any problems. Before reinstalling, I updated the BIOS on my Aspire 1410 laptop in the hopes that it would fix start-up issues, and it did. In the previous install, I had to frequently turn the machine off during start-up if it hung. Could be that files were corrupted. If the problem happens again with this fresh install, I'll probably file a bug.
