[BRLTTY] Ubuntu package build error

[Tobias Vinteus]

Hi, I receive the following error messages when trying to build the Ubuntu 
package från the git repository:

gbp:warning: Old style config section [git-buildpackage] found please 
rename to [buildpackage] gbp:warning: Pristine-tar branch "pristine-tar" 
not found gbp:error: Pristine-tar couldn't checkout 
"brltty_5.3.1.orig.tar.gz": fatal: Path 'brltty_5.3.1.orig.tar.gz.delta' 
does not exist in 'refs/remotes/origin/pristine-tar' pristine-tar: git 
show refs/remotes/origin/pristine-tar:brltty_5.3.1.orig.tar.gz. delta 
failed

Am I missing something?
Thanks,
Tobias
