xpra package is missing openssl as mandatory dependency on Ubuntu

[Florian Feldhaus]

I tried creating a minimal XPRA docker image and found that the xpra package is missing openssl as mandatory dependency on Ubuntu.

docker run -it ubuntu
root@f3aba763a523:/# apt-get update && \
>     apt-get install -y --no-install-recommends gnupg curl && \
>     curl http://xpra.org/gpg.asc | apt-key add - && \
>     echo "deb http://xpra.org/ focal main" >> /etc/apt/sources.list.d/xpra.list && \
>     apt-get update && \
>     apt-get install -y --no-install-recommends xpra
...
Setting up xpra (4.0.3-r27082-1) ...
/var/lib/dpkg/info/xpra.postinst: 16: openssl: not found
dpkg: error processing package xpra (--configure):

Thanks for the report.

That's fixed in r27421.
