I installed Skype in Ubuntu 14.04, but when I logged in to Skype, I only show and chat with my friends and can’t show any groups, I fixed it by the way:
Open chat box with any my friend and type:
/dumpmsnp #show details about your connection
And I showed log:
System: MSNP: Connection Data: * Status: LoggedOut
Ref:It’s LoggedOut => It is problem
To solve it, type:
/msnp24
Then log out and restart Skype. After that, type again:
/dumpmsnp
And I see:
System: MSNP: Connection Data (MSNP24): * Status: LoggedIn
And I also see all my groups in Skype, and the issue was solved.
