New Error message and removal problem

Since I have upgraded to Beta7 I am unable to remove any “Extras”.  I do not have Plex installed so I think it is not related to that problem.  I just tried to remove XMBC and it said Removal Successful but when I look at the “View Log” it says"

E: Could not get lock/var/lib/dbkg/lock-open(35:Resource temporarily unavailable)

E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Worked great till Beta7 now having a lot of issues to resolve.  A little help please.

 

 

I am having the same problem. Ever since this started I am unable to install anything else or update to the new Media Player. I can’t install or remove anything.

A workaround for removing XBMC can be found here: http://forum.firecore.com/topic/5275#comment-21360
