Answer 1

If you have this problem on a Synology NAS you can fix it by following the advice of the Synology support team:

Dear User,

This has been confirmed as a known issue and we will try to fix this issue in further MariaDB release. Sorry for your inconvenience.

Here is the workaround:

• Please try to telnet to your DS with "root" account and password (same as admin's)
• run the command "echo 1 > /var/services/mysql/VERSION"
• open MariaDB package from DSM will trigger update again
• type in the DB password and click Update will fix this issue

Answer 2

I had the same problem. Did alot of research and found out this solution. You need to run this command on ibdata1 sudo shadowprotect -u root | root

I dont know what this does.. but it worked for me.

Good luck.
