I ran into the same problem with openssl when installing the SDK on openSUSE 15.1, and found this post on TJC:
Essentially, libsl 1.0 is still required because the SDK still targets Ubuntu 16.04, which does not support libssl 1.1. Apparently, that is something they are working on – Ubuntu 16.04 will be eventually dropped as a supported environment, which then allows updating the libssl version.
Applying the suggested workaround in that thread does fix the installation issues however.
What other issues are you experiencing on non-Ubuntu variants? It seems to work well on a fairly large number of distros, judging by the lack of distro-specific complaints about incompatibilities that I’ve seen on TJC.
