Phoenix's questions

I installed terminator and it was working very well, but suddenly It stopped working.

When I add terminator repository, I got this error:

Command:

sudo add-apt-repository ppa:gnome-terminator/ppa

Error:

E: The repository 'http://ppa.launchpad.net/gnome-terminator/ppa/ubuntu bionic Release' does not have a Release file.

and When I ran terminator command in the terminal, I got this error:

File "/usr/bin/terminator", line 123
   except (KeyError,ValueError), ex:
                                ^
SyntaxError: invalid syntax
Error in sys.excepthook:

  File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:

    except (KeyError,ValueError), ex:
                                ^
SyntaxError: invalid syntax

I use python3.7 and Ubuntu18.04

Question:

How can I switch user automatically when I log in to an Ubuntu18.04 server?

For example: I want to switch from ubuntu user to new_user user:

# from
ubuntu@myserver:~$

# to
new_user@myserver:~/some_dir$

Thanks.

I want to upgrade from Ubuntu18.04 to Ubuntu19.10 but I got this error message.

Question: What should I do to fix this issue and What is the root of the problem?

Third-party sources disabled

Some third-party entries in your sources.list were disabled. You can re-enable them after the upgrade with the 'software-properties' tool or your package manager.

Thanks

Question:

How I can run polipo with supervisorctl command?

I know I can run polipo with systemctl:
