Get it
If you've already added the repository, just run:
sudo apt install hitman
First-time setup (add repository)
curl -fsSL -o /tmp/colaapps-archive-keyring.gpg \
https://colaapps.com/repo/colaapps-archive-keyring.gpg &&
sudo install -D -m 0644 /tmp/colaapps-archive-keyring.gpg \
/etc/apt/keyrings/colaapps-archive-keyring.gpg
sudo tee /etc/apt/sources.list.d/colaapps.list > /dev/null <<'EOF'
deb [signed-by=/etc/apt/keyrings/colaapps-archive-keyring.gpg] https://colaapps.com/repo stable main
EOF
sudo apt update
sudo apt install hitman
The first two commands install the ColaApps signing key, so apt verifies every index it
downloads. Needs curl. Debian and Ubuntu.
Added ColaApps before, with [trusted=yes]? That turns
signature checking off — run the block above again, it overwrites the old line.
About
Hitman is a desktop and web SSH connection manager. It keeps an encrypted ed25519/PEM key vault, opens multi-tab xterm.js terminals with resizable split-pane layouts (single / vertical / horizontal / 2x2), organises hosts into connection groups, and supports DoIt OIDC single sign-on with an offline password fallback. Ships as a self-contained Windows installer (bundled Node server, no separate runtime required).
