Software center does not load any content

[omichalek]

1) I open Software center
2) It does not load anything in the "all software" tab nor anything in the "installed" section
3) the "history" tab does load after a while

When opening from Terminal, this is the output:

please, what can I do? I tried reinstalling it in many ways and removing various other packages but my software-center still does not work

Hi omichalek, and thank you for your bug report. This issue and its fix is being tracked over in bug 891499, so I will mark this one as a duplicate of that.

Per the other report, it appears that a local cache file that Software Center uses has become corrupted and that is causing this issue. First, so that we can take a look at the file to see exactly what went wrong, could you please attach the following file to bug 891499?:

   /var/lib/apt-xapian-index/cataloged_times.p

After you've done that, you can restore normal Software Center operation as follows. Please shut down Software Center (if it is running) and type the following command into a terminal window to delete the corrupted file:

  $ sudo rm /var/lib/apt-xapian-index/cataloged_times.p

After this, Software Center should start normally. Please let us know if it does not, or if have you any further problems.

Thank you again!

You mean that bug is duplicate of mine, right? Just kidding, thank you for the note! I attached the file there already, but deleting it does not solve my problem...
