Debian 9 “stretch” turned out to be a stretch indeed. A stretch of my patience and imagination it is. I finally got around to upgrading my desktop and servers to the latest stable and I am not amused. Oh, being on Debian for nearly 20 years I did plenty of upgrades and none of them were painless. Most of the time I actually ended up scrapping the system and installing fresh copies of servers to make sure things work. Recently it was getting better though and I did not see too many angry shouts about the upgrade so I decided to give it a go. I marked up this weekend for the upgrade because experience taught me I was going to need time to fix things before the work starts on Monday.

Well, all right, so on the desktop many applications were simply uninstalled. Fine, when I need something and I notice it missing I install the tool again. That’s annoying but no big deal really. The upgrade itself failed, predictably, but with a little push from our friend ‘apt-get install -f’ the upgrade worked its way through and actually completed, which was a pleasant surprise overall. On the servers though things are not looking good at all.

The update went fairly quickly and without errors so I was amazed with the smooth action. I did feel a little suspicious but after reading through the apt-listchanges did not see anything Earth shattering and felt reassured. Little did I know of what the next hours would bring… The mail server went quietly away and would not start giving me weird errors. I was certain I read about postfix updates in the apt-listchanges but this did not look like anything described there.

After a while I realized that I am looking at some strange errors and configuration of MariaDB instead of the MySQL. Oh, my! That was not mentioned anywhere during the upgrade, was it? No, really! Debian has quietly yanked the MySQL out of my server and installed MariaDB instead. Moreover, it pretended to port my DB to MariaDB, meaning they were now not compatible with MySQL!

Fantastic. So I headed to the MySQL sites where folks of Oracle actually give a fair warning that, yes, Debian will silently replace the database on upgrade. And Debian did not mention it except to note triumphantly that they provide now a much better and transparently compatible database in a press release.

Well, I tell you what. The MariaDB is not transparently compatible. It breaks … -->
