I have a physical host, with wired GigE internet, 16GB RAM, and a 4T HD with Centos 7.8 KDE Plasma desktop installed, fully yum updated, and recently rebooted.
Based on this article – I did the following, attempting to get skype for linux to work:
Selecting “Skype” from the Applications –> Internet menu does not work, nothing appears on the screen.
Executing “skypeforlinux” at the command line immediately returns to the command prompt without any message, nor error.
I’ve checked /var/log and the only log file written to during this time is ‘messages‘.
The relevant output is as follows:

A google search on the relevant error message, “Package ‘skypeforlinux‘ isn’t signed with proper key” finds an old 2019 page in a foreign language (russian
https://www.linux.org.ru/forum/general/15233544
) but even when translated, doesn’t seem to be of much help.Secondary searches of Microsoft’s site for this error does not return any results.
I’ve reviewed other links/URLs for ‘installing skype for linux‘, all of them show essentially the same commands/steps, and success you do here on tecmint.com.
Finally, there seems to be no way to inform Microsoft of this issue, unless one signs up for a Microsoft account—which I have no need of. Sigh.
Any help in addressing this error is greatly appreciated.
Doesn’t work on Centos 7. No errors can be found. It launches and ps ax | grep skype shows it running. I guess it just doesn’t work…
@William,
Try to start the Skype from commandline, and see for any errors on the terminal.
