Comment 37 for bug 249824

My package version containing a tilde (1:9.5.0.dfsg.P2-1ubuntu3~ppa3) should work as a half-increment. It's higher than 1:9.5.0.dfsg.P2-1ubuntu2 (current), but should be lower than 1:9.5.0.dfsg.P2-1ubuntu3 (future/final). Assuming this version number or higher will be used by the final push, it will automatically supersede the ppa packages. Of course, you're also free to just remove my ppa from your sources list at any point and install a specific version via apt-get instead.
