apt install unregistry fails outright — unregistry is not in the official Debian or Ubuntu archives at all. Add the deb.griffo.io
repository below and sudo apt install unregistry gives you the current
release on Debian and Ubuntu alike — currently unregistry 0.4.3
(updated 2026-08-17).

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

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