Thanks Andreas for this report. Apparently the same problem happens in Eoan too. The minimal steps to reproduce are:
1. start a fresh LXD container 2. apt update 3. apt install apache2 libaprutil1-dbd-mysql 4. a2enmod authn_dbd (also enables the dbd module) 5. systemctl restart apache2 6. curl localhost => It works! 7. echo DBDriver mysql > /etc/apache2/conf-available/dbd_mysql.conf 8. a2enconf dbd_mysql 9. systemctl reload apache2 This last reload fails on Eoan and Focal with error: apachectl[2695]: AH00526: Syntax error on line 1 of /etc/apache2/conf-enabled/dbd_mysql.conf: apachectl[2695]: Can't load driver file apr_dbd_mysql.so apachectl[2695]: Action 'graceful' failed. but succeeds on Bionic. ** Changed in: apache2 (Ubuntu) Status: New => Triaged ** Changed in: apache2 (Ubuntu) Importance: Undecided => High ** Also affects: apache2 (Ubuntu Focal) Importance: High Status: Triaged ** Also affects: apache2 (Ubuntu Eoan) Importance: Undecided Status: New ** Changed in: apache2 (Ubuntu Eoan) Status: New => Triaged ** Changed in: apache2 (Ubuntu Eoan) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Server/Client Support Team, which is subscribed to apache2 in Ubuntu.
