Re: Updates hang on skype
You don't have to uninstall skype just because there are no more updates for it via dnf. I have a number of packages in F40 that stopped getting updates long ago, including one from F9. Packages get abandoned and no longer maintained—it happens all the time.
To avoid the dnf errors there are several ways you can do that. For example, the repo that provides skype should have a file in /etc/yum.repos.d, possibly called "skype-stable.repo" or "microsoft-skype" (I don't know if that is the name, you'll have to check). Assuming no other applications are provided by that repo that you want to keep, you can either delete that file or set "enabled=0" in the file where currently it has "enabled=1". You could also run "dnf config-manager --set-disabled <name_of_the_repo>" as root (e.g. "dnf config-manager --set-disabled skype-stable"). Another way is to set "excludepkgs=skypeforlinux" in the /etc/dnf/dnf.conf file (assuming skypeforlinux is the name of the package).
