💠 apt install oh-my-posh

⚡ The short answer. On a stock system apt install oh-my-posh fails outright — Oh My Posh is not in the official Debian or Ubuntu archives at all. Add the deb.griffo.io repository below and sudo apt install oh-my-posh gives you the current release on Debian and Ubuntu alike — currently oh-my-posh 30.6.5 (updated 2026-08-17).

📦 Add the repository, then apt install oh-my-posh

Step 1: Add repository & key

Run the commands
sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | sudo gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg
echo "deb [signed-by=/etc/apt/keyrings/deb.griffo.io.gpg] https://deb.griffo.io/apt $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null
sudo apt update
install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg

apt update

Step 2: apt install oh-my-posh

sudo apt install -y oh-my-posh
apt install -y oh-my-posh

🔄 How to apt install the latest Oh My Posh

Once the repository is added there is no separate "install latest" command — apt already resolves to the newest version this repository serves, and that is rebuilt within hours of every upstream Oh My Posh release. To move an existing install up to the latest version:

sudo apt update && sudo apt install --only-upgrade oh-my-posh
apt update && apt install --only-upgrade oh-my-posh

Or upgrade everything on the machine at once with sudo apt update && sudo apt upgrade. To see which version you would get before installing, run apt policy oh-my-posh.

❓ Common questions

Does apt-get install oh-my-posh work too?

Yes. apt and apt-get read the same sources, so sudo apt-get install oh-my-posh is equivalent. apt is the friendlier front-end; apt-get is the stable one to prefer inside scripts.

Why doesn't apt install oh-my-posh work out of the box?

Oh My Posh is not packaged in the official Debian or Ubuntu archives, so a stock system has nothing to install and apt install oh-my-posh fails with "Unable to locate package". Adding this repository gives apt a source that carries Oh My Posh and keeps it current.

Which Debian and Ubuntu releases are supported?

Every currently supported release listed in the table above. The $(lsb_release -sc) in the setup command picks the right suite for the machine you run it on, so the same three lines work everywhere.

Is this repository trustworthy?

It's an unofficial repository maintained by Dario Griffo. Packages are built automatically from official upstream Oh My Posh releases, the packaging is open source at dariogriffo/oh-my-posh-debian, and the whole archive is GPG-signed. Several upstream projects link to it from their official installation docs.
