After installing itunes via Playonlinux, the Ubuntu Software Centre refuses to open. I did get an error message that iTunes was not properly installed and should be reinstalled. But I cannot open the Software Centre to uninstall iTunes. My laptop is also now much slower.

How do I fix it?

  • The Software Center will not be able to help you install or uninstall Itunes. Open a terminal window (ctrl+alt+t) and enter the commands sudo apt-get update and sudo apt-get -f install - please paste any error outputs from those programs into your question. – Charles Green Aug 8 '14 at 14:45
  • After entering sudo apt-get update I got the following:E: Type ‘<!DOCTYPE’ is not known on line 1 in source list /etc/apt/sources.list.d/playonlinux.list E: The list of sources could not be read. – user313544 Aug 10 '14 at 6:29
  • After entering sudo apt-get -f install, I got the following response: – user313544 Aug 10 '14 at 6:31
  • After entering sudo apt-get -f install, I got the following response: Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: firefox-locale-af libglademm-2.4-1c2a Use 'apt-get autoremove' to remove them. 0 to upgrade, 0 to newly install, 0 to remove and 3 not to upgrade. – user313544 Aug 10 '14 at 6:32
  • Then I entered apt-get autoremove and got the following:E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root? – user313544 Aug 10 '14 at 6:35

If you want to remove iTunes and fix the Software Center:

  1. Uninstall iTunes by deleting the ~/.playonlinux directory, in Terminal (may need to prepend sudo) rm -rf ~/.playonlinux
  2. Restart your computer
  3. Update your sources with sudo apt-get update
  4. Try opening Software Center
