apt install k9s fails outright — k9s is not in the official Debian or Ubuntu archives at all. Add the deb.griffo.io
repository below and sudo apt install k9s gives you the current
release on Debian and Ubuntu alike — currently k9s 0.51.0
(updated 2026-08-17).
📦 Add the repository, then apt install k9s

apt updateStep 2: apt install k9s
sudo apt install -y k9sapt install -y k9s🔄 How to apt install the latest k9s
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 k9s release. To move an existing install up to the latest version:
sudo apt update && sudo apt install --only-upgrade k9sapt update && apt install --only-upgrade k9sOr 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 k9s.

❓ Common questions
Does apt-get install k9s work too?
Yes. apt and apt-get read the same sources, so
sudo apt-get install k9s is equivalent. apt is the friendlier
front-end; apt-get is the stable one to prefer inside scripts.
Why doesn't apt install k9s work out of the box?
k9s is not packaged in the official Debian or Ubuntu archives, so a stock system has nothing to install and apt install k9s fails with "Unable to locate package". Adding this repository gives apt a source that carries k9s 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 k9s releases, the packaging is open source at dariogriffo/k9s-debian, and the whole archive is GPG-signed. Several upstream projects link to it from their official installation docs.
