Simply installing libssl1.1 is not going to change the dynamic libraries
used by installed programs.
ii libssl1.0.2:amd64 1.0.2r-1~deb9u1 amd64 Secure Sockets Layer toolkit - shared libraries
ii libssl1.1:amd64 1.1.1n-0+deb11u4 amd64 Secure Sockets Layer toolkit - shared libraries
ii libssl1.1:i386 1.1.1n-0+deb11u4 i386 Secure Sockets Layer toolkit - shared libraries
ii libssl3:amd64 3.0.9-1 amd64 Secure Sockets Layer toolkit - shared libraries
ii libssl3:i386 3.0.9-1 i386 Secure Sockets Layer toolkit - shared libraries
If a program (e.g. /usr/bin/openssl) is dynamically linked against
libssl.so.3, then it's going to use libssl3, no matter how many older
versions of libssl with different sonames are installed.
If the issue is something like "libssl3 version 3.0.8-1 works, but
version 3.0.9-1 does not" then yeah, installing an older version of
libssl3 might work around the issue.
