mysql 5.6 => 5.7 upgrade confusion

When I upgraded a system to 11.3-RELEASE some time ago, I
reinstalled all packages, which unfortunately installed mysql
5.7; I had been running 5.6. In trying to decipher the upgrade
process, everything I see implies the server will start.
When I attempt to start the server as a non-priveledged user
(formerly possible) I get this:
2020-05-18T03:17:18.343412Z 0 [Warning] Insecure configuration for --secure-file-priv: Current value does not restrict location of g
enerated files. Consider setting it to a valid, non-empty path.
2020-05-18T03:17:18.343569Z 0 [Note] mysqld (mysqld 5.7.29-log) starting as process 32850 ...

2020-05-18T03:17:18.376691Z 0 [ERROR] InnoDB: Unable to create temporary file; errno: 13
So I tried starting as root, which created a whole new/different data
and config directory (no surprise there) but failed with this:
mysqld: Table 'mysql.plugin' doesn't exist
2020-05-18T02:05:35.875695Z 0 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

2020-05-18T02:05:36.300321Z 0 [ERROR] Aborting
I'm confused as to how to proceed from here. I need to run
mysql_upgrade as a normal user; but I clearly need to run it first
as root; but I can't run it if the server won't start because of
the plugin table issue reported above.
confused, as usual...
thanks for any enlightenment,
