Bug: https://bugs.launchpad.net/ubuntu/+source/strongswan/+bug/1861971

Many fixes in upstream and Debain that are nice to get for 20.04

One change is the addition of DRBG which is in libstronswanpluging.
That packages is in main so lets be extra careful, but it does not add a new dependency:

root@d10-sid:~# ldd /usr/lib/ipsec/plugins/libstrongswan-drbg.so
        linux-vdso.so.1 (0x00007ffe89033000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9d00b79000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f9d00d51000)

Note: This package is affected by the empty-directory-issue but I have the old meregs and can quickly recover the history.
