When I try to install any software from ubuntu software center it comes with error:

An unhandled error occured
There seems to be a programming error in aptdaemon. This is the software that allows you to install/remove software and to perform other package management related tasks.
details
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 961, in simulate
    trans.unauthenticated = self._simulate_helper(trans)
  File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1085, in _simulate_helper
    return depends, self._cache.required_download, \
  File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 226, in required_download
    pm.get_archives(fetcher, self._list, self._records)
SystemError: E:I wasn't able to locate file for the ttf-mscorefonts-installer package. This might mean you need to manually fix this package.

Please help me!

Possibly this error was caused when you interrupted the install or removal of Wine.

Try running the following in a terminal session:

sudo dpkg --configure -a
sudo apt-get update
sudo apt-get upgrade

Edit:

When you see in the terminal window appear "Package configuration - 

┌─────────────────┤ Configuring ttf-mscorefonts-installer ├─────────────────┐

press tab or I think the arrow keys until the "OK" is highlighted.

Then press Enter to accept the license agreement

  • Running 1st command - dpkg: error: dpkg status database is locked by another process – Dei Aug 15 '11 at 08:15
  • Running 2nd command - Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? – Dei Aug 15 '11 at 08:16
  • Running 3rd command - E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? – Dei Aug 15 '11 at 08:17
  • 2nd and 3rd command worked. after running 3rd in a terminal window appear Package configuration - ┌─────────────────┤ Configuring ttf-mscorefonts-installer ├─────────────────┐ After I read the license agreement can just close the terminal window, but it says - There is still a process running in this terminal. Closing the terminal will kill it. I think thats where problem first appeared. When I installed wine I had the same window and I just closed it. What do I do with this window? – Dei Aug 15 '11 at 08:38
  • Make sure you do not have synaptic manager running. With regards to the license agreement window - press tab or I think the arrow keys until the "OK" is highlighted. Then press Enter to accept the license agreement. – fossfreedom Aug 15 '11 at 09:35

  • The OP seems to have forgotten to tick this answer, but it works perfectly. I just ran into this problem today. When I came to the Configuring ttf-mscorefonts-installer EULA screen, I couldn't figure out how to choose "Ok" (all you have to do is press tab) so I closed the terminal. Afterward, I couldn't install anything. @fossfreedom's method fixed everything. – Herbert Nov 24 '11 at 01:45

What version of Ubuntu are you running? (I would add this as a comment to your question but I can't find the button.)

The error message seems to suggest it is just a bug in aptdaemon or software-center, which you might want to repot over at bugs.ubuntu.com.

What you might do is run Synaptic Package Manager and, under Custom Filters in the bottom left-hand corner, click the Broken filter on the left-hand side, and try to reinstall all packages, if any, that come up.

  • Ubuntu 11.04 Can not run Synaptic Package Manager. It comes with an error - Unable to get exclusive lock

    This usually means that another package management application (like apt-get or aptitude) is already running. Please close that application first. Everything seems to be closed.

    You might want to add the version number to your question :)

    Have you tried running Synaptic first thing after you start up your computer?
