Upgrade debian 10.4 to 10.10

[Didier Decoodt]

Hi all

I have a site on debian 10.4 with apache, and I have implemented brotli

Today I would like to upgrade my debian to 10.10 (or 11), but during the upgrade, Apache don't want anymore restart

Have you an idea of the problem? May be I have missed someting...

Thank you very much for your help
