Add the repository

A Cyclop OS machine is already set up: the installer writes these files for you. The steps below are for a machine you configure by hand.

1Install the signing key

apt checks every index against this key and refuses anything else.

sudo curl -fsSLo /usr/share/keyrings/cyclop-os-keyring.gpg https://packages.cyclop-tech.com/cyclop-archive-key.gpg

Check the fingerprint with gpg --show-keys /usr/share/keyrings/cyclop-os-keyring.gpg and compare it with the one below.

2Add the Community source

A deb822 file in /etc/apt/sources.list.d/cyclop.sources, then refresh.

sudo tee /etc/apt/sources.list.d/cyclop.sources <<'EOF'
Types: deb
URIs: https://packages.cyclop-tech.com/noble/community
Suites: noble
Components: main
Signed-By: /usr/share/keyrings/cyclop-os-keyring.gpg
EOF
sudo apt update

3Paid editions

Pro, Gaming and Education are not added by hand. When you activate a licence, during installation or later, the machine registers itself, receives its own access token and gets its edition repository. Without a valid licence the server answers 401 or 403.

A token works only on the machine it was issued to. When a licence ends, the machine keeps working on Community.

4Source packages

The Community repository also publishes its sources. Add a deb-src entry to fetch them with apt source.

sudo tee /etc/apt/sources.list.d/cyclop-src.sources <<'EOF'
Types: deb-src
URIs: https://packages.cyclop-tech.com/noble/community
Suites: noble
