The focal-security version is currently 2.4.41-4ubuntu3.23, and there i don't find any reference of ap_proxy_should_override in the source package.
The function was added in https://github.com/apache/httpd/commit/a545608f8355fba22eee1edf86a63f0be785f595 which i think ships since version 2.5.0. There was a backport to 2.4.47 in https://github.com/apache/httpd/commit/41cdf59f2343f11fca5152542d843c3403c233db - so i wonder how that would be part of your 2.4.41. It could help to run apache using `strace -fy` so we can see at which point linking error is shown. Do you have any other plugin modules installed/active? Did the load of mod_proxy_http2.so work before? ** Changed in: apache2 (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163447 Title: apache2-bin 2.4.41-4ubuntu3.23+esm6 ships an incompatible mod_proxy_http2.so that references the undefined symbol ap_proxy_should_override.
