I did do all the upgrades in sequence over the years. This is the first time I've really tried to use the innodb based stuff (mythweb and mythweather), so it could have gotten messed up anywhere along the way.
Checking my backups: the timestamp on the files indicates they were last written when I was running 10.10, but I'm also seeing the same error messages during that time. I tried the first couple steps you recommended, but they didn't really work right. # mysqldump --defaults-extra-file=/etc/mysql/debian.cnf --all-databases > ~/all_tables.sql mysqldump: Got error: 1286: Unknown table engine 'InnoDB' when using LOCK TABLES It sounds like it's finding InnoDB stuff, but can't read it properly. # mysql --defaults-extra-file=/etc/mysql/debian.cnf -e "SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE ENGINE='InnoDB'" The select returns nothing because that engine never loaded. It doesn't necessarily mean there isn't anything there. Removing the ib* files (after backing them up) did allow InnoDB to load. I also had to remove /var/lib/mysql/mythconverg/weather* to keep it from complaining about old/bad .frm files. re-installing the mythweb plugin did re-created the tables. mythweb now works for me. I think this means that the bug is probably somewhere in migration (possibly in a previous version), but (hopefully) isn't reproducible. Thank you so much for the hand holding.
