On Ubuntu 20.04 I am trying to run the following command
sudo apt-get update
which fails with the following error:
E: Failed to fetch https://dl.bintray.com/loadimpact/deb/dists/stable/InRelease 403 Forbidden (IP: 18.104.22.168 443) E: The repository 'https://dl.bintray.com/loadimpact/deb stable InRelease' is not signed. 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.
I already tried to remove stuff like this
sudo rm -fr /var/lib/apt/lists/*
but this did not help. Anything else I can try to fix this problem?
