Unable to reconfigure MySQL Server 5.7.29 after 8.0.19 upgrade

[Charles Finkenbiner]

After installing the 8.0.19 update I find 2 items I can't reconfigure.

MySQL Server 5.7.29 shows these errors, which happens during step 2 (backup):

Sample and Examples is the 2nd reconfigure problem. The status shows as 'stopped' even tho my local MySQL server is running. Since the server seems stopped I can't get pass the root password check, always fails because server is stopped.

I did find a bug report for the MySQL Server problem but it was unconfirmed.



Thanks for any help,
