Oh, it not work in Ubuntu 20.4 🙁
nano /etc/apache2/mods-available/mpm_prefork.conf can’t contain LimitUIDRange 0 2000 parametrs.

my mpm_prefork.conf :

# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# MaxRequestWorkers: maximum number of server processes allowed to start
# MaxConnectionsPerChild: maximum number of requests a server process serves

StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxRequestWorkers 150
MaxConnectionsPerChild 0

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

I’m experiencing same issue but unfortunately I cannot using this solution. Because my server is shared with several users with multiple websites. So I think allowing root for users may case security issue.

Thank you!

That helped!

Further readers, please NOTE that you have to set the “LimitUIDRange” parameter, not the “LimitGIDRange”, which is bold in the text above.
