snappy ubuntu core install basic packages
How to install basic package on snappy Ubuntu core, like nano git wget etc.
I tried the dpkg -i ***.deb ,but there are also need some dependent packages
The workaround posted by Lin is fine on 15.04 but in 16.04 LTS you will have a different mechanism, called the 'classic dimension', that will give you a traditional deb based filesystem alongside the snappy filesystems. That way you can use git or other tools on a snappy system and pop back and forth between the snappy and classic dimensions.
