The packagecloud install script does not recognize Linux Mint as using Ubuntu packages.

If you open "Software Sources" you can edit the additional repository URL to end with tabby/ubuntu/jammy main as Mint 21 is based off of Ubuntu Jammy LTS. You can check this using cat /etc/os-release and looking for UBUNTU_CODENAME at the bottom.

$ cat /etc/os-release 
NAME="Linux Mint"
VERSION="21.3 (Virginia)"
ID=linuxmint
ID_LIKE="ubuntu debian"
PRETTY_NAME="Linux Mint 21.3"
VERSION_ID="21.3"
HOME_URL="https://www.linuxmint.com/"
SUPPORT_URL="https://forums.linuxmint.com/"
BUG_REPORT_URL="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/"
PRIVACY_POLICY_URL="https://www.linuxmint.com/"
VERSION_CODENAME=virginia
UBUNTU_CODENAME=jammy

Use the correct release for your system. LMDE should work the same way, just using the matching Debian release instead of Ubuntu, but I have not tested this.

Next do sudo apt update and it should work.
