Numbers and strings are split before comparison. '.D' is compared to '.' and is considered higher.

Yes, you can add an epoch [1] to the Debian version, but then you always have to carry the epoch. There will be no way back! Example: 1.D9 << 1:1.14 << 1:2.1 [1] For details see Debian policy §5.6.12 Version -- Benjamin Drung Debian & Ubuntu Developer -- Ubuntu-motu mailing list Ubuntu-motu@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-motu
