Unable to build docker container

[x1ddos]

First, I think libssl-dev is missing during the build. Moved it like in this patch:

But even then, I suspect it fails because the installed libssl version is newer than what's expected:

$ docker build -t raider .
...
default-libmysqlclient-dev is already the newest version (1.0.5).
libssl-dev is already the newest version (1.1.1d-0+deb10u3).

Attached full build.log.

I'd prefer to actually not use a container but my libssl-dev version on host is newer, too. So, same result. I'll try and see if I can bump deps versions and make them use newer libssl.
