I downloaded and installed Skype, but by clicking the icon it just does not start.
What should I do?
It's always good to open a terminal and issue the command from there. Failure will at the least reports some output.
Open a terminal and issue the command:
Just to be sure. You downloaded and installed Skype through Ubuntu's Software Center.
I recommend doing it this way. But in all cases, Skype has a particular issue that if you start it 2 or more times it gets stuck if you did not close it properly.
Do the following in a terminal:
sudo killall skype or
sudo killall -9 skype. That should force skype to close even if you do not see it. It kills the Skype process.
After which I also recommend putting the Skype icon in the Launcher. This way, if you double click on it, it will not open twice. It will just open normally and the second click will make it get focus.
I've had the same problem. Followed the answer here https://askubuntu.com/a/322347/115308, and it is working now.
Make sure that you install 32-bit / 64-bit Skype on respective hardware. Installing from the Ubuntu Software Center automatically decides what version is appropriate.
When starting Skype, a native 32 bit binary, in a 64 bit environment you might run into the following error and Skype refuses to start:
skype: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
So far I only had this problem on 64 bit. The following solution solved it:
# ln -s /usr/lib/mesa-diverted/i386-linux-gnu/libGL.so.1 /usr/lib/i386-linux-gnu/
The fact that the problem was posted in such a general form makes it applicable to recent developments.
In Kubuntu 18.04 downloading and installing the deb file I can only start it once, log in, without any way of accessing contacts etc. Closing and restarting it appeared in tray but would not start. Running
skype in terminal it says uninstalled, recommends to use
sudo snap install skype
Doing that (after uninstalling
skypeforlinux) it asks me to use
sudo snap install skype --classic
which successfully installs a working Skype.
