How can I fix terminator? It doesn't work

When I run terminator in terminal, it doesn't work. The error is this:

$ terminator

  File "/usr/bin/terminator", line 119
    except (KeyError,ValueError), ex:

                                ^
SyntaxError: invalid syntax

Error in sys.excepthook:

Traceback (most recent call last):

    import apt_pkg

ModuleNotFoundError: No module named 'apt_pkg'


Original exception was:

  File "/usr/bin/terminator", line 119

    except (KeyError,ValueError), ex:
                                ^

SyntaxError: invalid syntax

How can I fix it? I use Ubuntu 16.04.

Solution 1:

I fixed it by editing /usr/bin/terminator and changing the python version. First, open the file with:

sudo nano /usr/bin/terminator

Then, change the first line from this:

#!/usr/bin/python

To this:

#!/usr/bin/python2

Finally, save the file and you're ready to go!

Solution 2:

Terminator require python2 libraries but from your output it seems it is using python3 to run. Also, according to release notes of Ubuntu 18.04,

Python 2 is no longer installed by default. Python 3 has been updated to 3.6. This is the last LTS release to include Python 2 in main.

To install Python2 in 18.04, run:

sudo apt install python-minimal

Solution 3:

Consider to reinstall packages with apt_pkg with

sudo apt-get install --reinstall python-apt python3-apt

and to be completely sure reinstall Terminator with

sudo apt-get install --reinstall terminator
