After recent updates the global menu dissapeared as mentioned in this question (https://askubuntu.com/questions/297743/libre-office-shows-blank-menu-and-then-crashes). I tried to file a bug report by typing out
A notification Window says
"This Problem cannot be reported. This is not an official Ubuntu package. Please remove any third party packages and try again."
It occured to me that I may had a manually installed version of libreoffice. So I typed the following in terminal
sudo apt-get remove --purge libreoffice* sudo apt-get clean sudo apt-get autoremove
And installed libreoffice by typing the following in terminal
sudo apt-get install libreoffice
After that, I still can't file a bug via ubuntu-bug libreoffice. I get the same message. What can I do now to get a menu in libreoffice (back). How do i remove third party packages, if I do not know them?
