Comment 9 for bug 79364

Another time the bug was found on hardy

apt-build was working normally, until the update-manager updated it to

$ apt-build -v
apt-build version 0.12.31ubuntu1

Since that, I got the next problem:

$ sudo apt-build source mysql-server
Missing source package name for source_by_source().

$ sudo apt-build install mysql-server
mysql-server will not be built because it doesn't have a source package.
Missing source package name for source_by_source().

$ sudo apt-get source mysql-server
