Package: apache2 Version: 2.4.33-3 Severity: normal Dear Maintainer,
Tim Bishop filed this bug in Ubuntu: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1782806 showing what appears to be a typo in a maintainer script: https://salsa.debian.org/apache-team/apache2/blob/master/debian/debhelper/apache2-maintscript-helper#L290 a2query -m "$mpm_$MPM" > /dev/null 2>&1 || a2query_ret=$? The argument to -m was probably meant to be "mpm_$MPM", as the shell function where this statement lives explicitly requests that the mpm module name should not have a "mpm_" prefix. The fix should be as simple as this: --- a/debian/debhelper/apache2-maintscript-helper +++ b/debian/debhelper/apache2-maintscript-helper @@ -287,7 +287,7 @@ apache2_switch_mpm() fi local a2query_ret=0 - a2query -m "$mpm_$MPM" > /dev/null 2>&1 || a2query_ret=$? + a2query -m "mpm_$MPM" > /dev/null 2>&1 || a2query_ret=$? case $a2query_ret in 0) Thanks!
