I lately installed python 3.5 from the source, but I think I did something wrong during the installation or linking. After this I have problem installing any Ubuntu packages. For example, add-apt-repository doesn't work, even after reinstalling software-properties-common.
$ add-apt-repository bash: /usr/bin/add-apt-repository: /usr/bin/python3: bad interpreter: No such file or directory
Also, apt-get install will give me this errors

Also, trying to add ppa gives the following error
$ sudo add-apt-repository ppa:dhor/myway sudo: unable to execute /usr/bin/add-apt-repository: No such file or directory
What's going on, any ideas?
