I updated to Ubuntu 20.04. When I use the default terminal, everything is fine. But if try to use terminator, I cannot use sudo. I get permission denied. Again, only when using terminator.

How can I sudo from the terminator? I really would like to continue to use a terminator.

Edit: I just also noted that it cannot find make either. I guess it's all messed up. I'll try to uninstall it and install again I guess.

I had the same issue on Ubuntu 20.04 when downloading Terminator from Ubuntu Software.

Installing Terminator from terminal with apt install terminator resolved this issue.

on 20.04.2 LTS, i have gotten rid of my broken snap (v1.9.1) with:

sudo snap remove gnome-terminator

but if you haven't installed it via snap, you can uninstall it with:

sudo apt --purge remove terminator

then you have 2 OPTIONS (both of which i tested and work):

  • v2.0.1

via NEW repo via NEW and actively maintaining team: https://github.com/gnome-terminator/terminator/blob/master/INSTALL.md

sudo add-apt-repository ppa:mattrose/terminator
sudo apt update
sudo apt install terminator
  • or v0.98

via OLD classic route:

sudo add-apt-repository ppa:gnome-terminator
sudo apt update
sudo apt install terminator

however you will get error when doing:

sudo apt update

something like this (error number and IP will be different):

Err:10 http://ppa.launchpad.net/gnome-terminator/ppa/ubuntu focal Release
  404  Not Found [IP: 91.189.95.85 80]
Reading package lists... Done
E: The repository 'http://ppa.launchpad.net/gnome-terminator/ppa/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

because Terminator's repo has been stale for while now :( https://launchpad.net/~gnome-terminator/+archive/ubuntu/ppa

so i replaced focal with xenial (last one supported when you click on 'Technical details about this PPA' and then on drop-down 'Choose your Ubuntu version'), like this:

sudo nano /etc/apt/sources.list.d/gnome-terminator-ubuntu-ppa-focal.list

amended (my top) line:

deb http://ppa.launchpad.net/gnome-terminator/ppa/ubuntu focal main

to:

deb http://ppa.launchpad.net/gnome-terminator/ppa/ubuntu xenial main

then save and do again:

sudo apt update

and error is gone.
