The symptoms of my computer crashing was very similar to those reported in the comments section of a particular bug in an application that I download and get updates via a ppa.
Recently, the ppa's bug page showed that the bug has been fixed-released, but very little information was given about the fix. How can I find out exactly -
What did they actually do to fix the bug
When was it released
How can I be 100% sure that I have received the update (for example, is there an update history in Ubuntu that will tell me that this particular update was downloaded and installed, with a reference to that particular bug?)
