This issue started after I installed Diablo.
I have this library into the list of applications to update.

libbz2-1.0 , version 1.0.3.-2

However when I am trying to update I am getting an error message:
"Unable to update libbz2-1.0 Some application packages required for the update are missing. "

Now details:
"Unable to update
App packages missing libbz2-1.0(=1.0.3.1)"

However, I do have this library (bzip2 works and I did find libbz2-1.0 on path
/lib/libbz2.a
/usr/lib/libbz2.so.1.0->/usr/lib/libbz2.so.1.0.3
/usr/lib/libbz2.so.1.0.3

How can I resolve this issue? Red pill mode did not help me.
Thanks

You shouldn't update libbz2 per se, if some application ask that version, it will install automatically.
Moreover, I don't see that version in the extras or extras-devel repository, so I wouldn't recommend update it. Simply ignore it.

Could you tell me how can I see from what repository its is coming? I tried to switch off all repos I have 1 by 1, and this is still there

Open the terminal application and run "apt-cache policy libbz2-1.0"

Thanks very much for this tip. It turns out that the diablo repository for FBReader has a later version of libbz2-1.0 (1.0.3-2) than the base nokia repository (1.0.3-1).
