[Bio-Linux] Problem with package catalogue. Nothing can be installed anymore

[john vollmers]

Hello,
Ever since I ran into java-dependency problems while trying to install 
an external python module (Twilio), I cannot install or remove anything 
in biolinux anymore.

every time I try to open the ubuntu software center i get the following 
message:
"biolinux Items cannot be installed or removed until the package 
catalogue is repaired. Do you want to repair it now?"

But wen I click "OK" it always aborts the repair process with the 
message "Package operation failed" (however It won't let me look into 
the details).

When I look into the Software-Center history it seems that each time it 
tries to "repair the catalogue" it is actually trying to install 
"Oracle-Java8-installer" but fails every time.

what can I do?
