How-to: Use Wickr in Whonix ™
Security risk. Discouraged as per software installation best practices.
- Unsigned software. It is not possible to follow the security advice of always verifying software signatures since installation is thorough
snapwhich does not verify software signatures (yet?). 
- Only installable thorugh third party package manager
snapwhich is discouraged. 
- Wickr is non-freedom software. Discouraged as per avoid non-freedom software!

snap install --devmode wickrme
