Hi Otto, Thank you for your efforts in resolving this.
For the record, I'm not on the Ubuntu release or archive admin teams, but due to my existing involvement in the MySQL/MariaDB packaging team and in Ubuntu I guess it makes sense for me to get involved.

I believe both Debian and Ubuntu will hold the same opinion on this: now that the epoch bump has been published, we will have to live with it. I suggest that we: 1. Ask the Ubuntu archive admins to remove src:mariadb-10.2 (10.2.7-1) from the archive. I see that Debian has already done this, so Debian and Ubuntu will be the same. 2. Re-publish exactly your known good version mariadb-10.1 10.1.28-2 but bump the version string to 1:10.1.29-7really10.1.28. The binaries that will build from this will all have version 1:10.1.29-7really10.1.28 which is higher than all binaries previously published, so should publish fine. I believe this would be appropriate to fix the mess in Debian too. Therefore you can do this in Debian and we can sync it over in Ubuntu. This doesn't need to wait for step 1, but it might be wise to have the archive admins review this entire plan first. 3. Once the dust has settled, you can prepare a 1:10.1.28-8 or a 1:10.1.29-1 (if that exists) or a 1:10.2.7-1 at your leisure, and they can go into Bionic according to the normal freeze requirements. Again, you can continue uploading to Debian and we can sync over to Ubuntu as appropriate. Consequences: 4. Users already on the broken mariadb-10.2 will end up "upgrading" to mariadb-10.1, which isn't a supported data migration path as you point out. They will need to fix their systems manually - but as they were using pre-release software, I think this is acceptable even if unfortunate. 5. Everyone shipping MariaDB packages, including upstream, PPAs, etc, will need to follow the epoch bump in order for everything to work smoothly. This is, AIUI, unavoidable now. If a PPA does not do this, then users will end up downgraded, with a failed data migration and therefore broken. This is again unfortunate but I think acceptable: this is the risk of following a PPA. Options I'm deliberately opining against: 6. Going backwards in version numbers. AIUI, Launchpad will not permit this anyway and nor will Debian ftpmasters. 7. Directly fixing mariadb-10.2 without reverting mariadb-10.1 first by bumping it. Since Bionic is past feature freeze and mariadb-10.2 has always been broken, I think it's prudent to get the archive into a releaseable state first, and only then looking at bumping major versions. IMHO (but this is the release team's decision and not mine), we should consider 10.2 to have missed feature freeze since it has always been broken. Making 10.2 or 10.3 work in the archive for Bionic now should be breaking feature freeze so should follow the usual exception process. In any case, re-publishing mariadb-10.1 as I suggest should be comparatively trivial and will not impact any move to 10.2 or 10.3 whether in this cycle or in the future. Does this plan (steps 1 to 3 above) seem reasonable to everyone? Robie
