Title:
Software Center crash of there is a # comment in
/etc/apt/preferences.d/testing
Status in “software-center” package in Ubuntu:
Confirmed
Bug description:
If I create the file /etc/apt/preferences.d/testing with "# aaa" in it
Software Center will crash when I start it on Ubuntu 12.04 beta 1.
I am not 100% sure if # comments are allowed in these files but
Software Center should not crash like this even if I have added some
illegal chars in a config file.
As long as I do not add any # comments I can use the
/etc/apt/preferences.d/testing file but # comments are useful...
apt-get have no problems with these comments.
This is the output from software-center:
