As of today, I cannot login into my Skype account anymore ("Skype could not make a connection"). The Skype homepage says you need Skype 4.3 to log in, but in the LMDE repository, there is only version 4.2. I know that my smartphone installed a new version of Skype yesterday. What do I have to do?
The solution was to deinstall Skype 4.2 and to install the Skype 4.3 Debian package (multiarch) downloadable from the Skype homepage.
