Comment 41 for bug 1969247

Until such time the fix makes it into mainstream, this hack gets things going again for me.

I took a look at the contents of the directory /var/lib/mysql/#innodb_redo#
There was only a single file there which of course matched the filename identified in the /var/log/mysql/error.log and this was:

-rw-r----- 1 mysql mysql 0 Aug 1 19:10 '#ib_redo0'

I deleted it.

Mysql immediately restarted.

In addition, upon restarting generated these files within that same directory /var/lib/mysql/#innodb_redo#
