Ubuntu – Terminal not opening up after upgrading python to 3.7

18.04gnome-terminalpython3

I have upgraded python to version 3.7 and now my terminal is not opening up.

I followed this post https://jcutrer.com/linux/upgrade-python37-ubuntu1810

Commands I ran are as follows,

sudo apt-get install python3.7
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 2
sudo update-alternatives --config python3

Entered 2 for python3.7

I can't open terminal and run commands.

My ubuntu version is, Ubuntu 18.04.2 LTS

Best Answer

This way the upgrade to 3.7 is useless. You should edit the gnome-terminal file:

Open a terminal and issue the following commands:

cd /usr/bin
sudo nano gnome-terminal

Change #!/usr/bin/python3 to #!/usr/bin/python3.6.

This way you can still use the power of 3.7 and solve the issue with the terminal.
