There was a horrible botch in Ubuntu recently--they *renamed existing
packages in an existing release*, which means that as build-gnuradio
asks for packages, it fails to find them. WORSE, apt-get, even with
--ignore-missing, considers that asking for a package that isn't in the
repo to be a fatal error, so, it tends to abort the entire lots of
installs even if ONE of them is mis-named, which, up until Ubuntu
totally screwed the pooch, there wouldn't have been any.
I updated build-gnuradio late yesterday to properly name the mis-named
package, so, depending on when you grabbed build-gnuradio that fix may
not have been in place. Also, you can get more details about what
it's doing under the covers using the -v option.
