Bug#629319: Version number is not allowing more recent versions to be downloaded

[Andreas Tille]

Hi,

this is not a problem of the Debian package, but (most probably - I have
not checked) a problem of the Ubuntu package (or your Build system
including a Debian mirror).  The epoch (1:) was needed because of using
a different versioning scheme in the past.  To make sure the newer
versions become a higher version than the older upstream versions it was
necessary (and the only solution) to add the epoch.  If you drop the
epoch in the Ubuntu packaged version this will be regarded as lower than
the Debian package.  Alternatively you should drop the Debian mirrors
from your Build system and if there are no packages featuring the epoch
everything should be fine.

I could close this bug report immediately but I leave it as a remainder
for upgrading the package (and a Debian upgrade to latest upstream will
fix / work around your problem as well even if this is not the proper
fix in your situation as I tried to explain and will fail again if
Ubuntu tries to package a more recent version than Debian.

Kind regards

      Andreas.
