We have been using skype on CentOS for a long time. Even if the latest versions needed an extra step after each update:
sudo chmod 4755 /usr/share/skypeforlinux/chrome-sandbox
The latest version skypeforlinux.x86_64 0:18.104.22.168-1 completely broke it and it doesn't work any more. Any hint on how to continue using it is very much welcome. We have several working stations where this is required.
