1st: bash/shell scripts from home-directory give this error:
bash: ./script: /bin/bash: bad interpreter: Permission denied
2nd: exactly same scripts in /usr/bin are working fine
3rd: If you are loged in via ssh, then it doesn't matter, where the scripts are.
4th: One short look in /etc/passwd will show you, that the user "phablet" does not really exist anymore. (In 14.10 you could find user phablet in that file.)
So all in one: I think, that it is possible, that point 4 is the reason, that you can't execute bash-scripts. (In 14.10 there I had no problems with.)
