When I try installing Burg, I get the following error:
Package burg is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
Package burg-themes is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'burg' has no installation candidate
E: Package 'burg-themes' has no installation candidate
I am using Ubuntu 12.04, as a dualboot with Windows 7.
