[Pkg-mailman-hackers] mailman3-web config error with mysql

[Sun Zhiyong]

Hello,

When config mailman3-web with SQLite, it works OK. But when config it with mysql, it always says:

django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 767 bytes')
dpkg: error processing package mailman3-web (--configure):
 subprocess installed post-installation script returned error exit status 1

In /var/log/mailman3/web/mailman-web.log, there is below:
---------

If run $dpkg-reconfigure mailman3-web

It says mailman3-web is broken or not fully installed.
