There is strange things going on with Skype since Microsoft took over it. Weirdly, while using, it crashes and will not launch again. And it happens to a lot of people. Probably a problem with Ubuntu. Any ways, since there is no standard solution available, one cannot wait for the new updates from Skype (if any). So folks, here is a quick and dirty trick to solve this problem.
In your home/your_user_name (or simply call it ~ directory), there is a hidden Skype directory. It contains few files and shared.xml is one of them. Either delete this file or rename it. Use either of these commands:
mv ~/.Skype/shared.xml ~/.Skype/shared2.xml or rm ~/.Skype/shared.xml
After this, start Skype again, enter your login details.
If the problem still persists, try removing this file as well by using this command:
As suggested by a reader Arri, the same problem can be solved by removing the same shared.xml file from the following location:
Hopefully this works for you all! Questions, suggestions and feedbacks are welcomed.
