Blackfire uses a custom Debian repository to distribute its packages; it is compatible with most Debian-based distributions like Ubuntu and Linux-Mint.
wget -q -O - https://packages.blackfire.io/gpg.key | sudo dd of=/usr/share/keyrings/blackfire-archive-keyring.asc
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/blackfire-archive-keyring.asc] http://packages.blackfire.io/debian any main" | sudo tee /etc/apt/sources.list.d/blackfire.list
