How to solve this problem ?

[OleksandrKorovii]

Same problem on Ubuntu 22.04 LTS

[mbirth]

The version in Ubuntu is ancient.

Run this:

curl https://azlux.fr/repo.gpg | sudo apt-key add -
sudo apt-add-repository deb http://packages.azlux.fr/debian stable main

Then remove package ctop (Ubuntu version) and install the now available docker-ctop.

Just type ctop instead of docker-ctop

[sergeykad]

Installing from the repository does not work anymore due to security issues.
The only way it worked for me was by using these instructions.

E: The repository 'http://packages.azlux.fr/debian jammy Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Forget installing old ctop from system packages, just use pipx: pipx install ctop

I used pipx to install ctop on my Ubuntu-22.04 and it still doesn't work.
