Error: DASH shell not supported as system shell
The installer has detected that your system uses the dash shell
as /bin/sh. This shell is not supported by the installer.
You can work around this problem by changing /bin/sh to be a
symbolic link to a supported shell such as bash.
For example, on Ubuntu systems, execute this shell command:
% sudo dpkg-reconfigure -plow dash
Install as /bin/sh? No
