Hello,

my server Apache is broken after the Jessie upgrade.
Error is :
usr/lib/apache2/modules/mod_httpbl.so: undefined symbol: ap_get_server_version

More details :
sudo systemctl -l status apache2.service

Thanks for help or any clue.

Have you read the notes on Apache in the release notes? Maybe they can help you: https://www.debian.org/releases/jess...-httpd-incomat

Thanks for answer and help path.

Indeed I missed the upgrade path for Apache 2.2 to 2.4
So nothing related to the Jessie upgrade itself.
