Ubuntu is a Kopia orphan. So why not remove this section?

No one will ever get around to making Apt-Get actually work with Kopia. This section is just false hope.

Linux installation using APT (Debian, Ubuntu)

Kopia offers APT repository compatible with Debian, Ubuntu and other similar distributions.

To begin, install the GPG signing key to verify authenticity of the releases.

curl -s https://kopia.io/signing-key | sudo gpg --dearmor -o /etc/apt/keyrings/kopia-keyring.gpg

Register APT source:

echo "deb [signed-by=/etc/apt/keyrings/kopia-keyring.gpg] http://packages.kopia.io/apt/ stable main" | sudo tee /etc/apt/sources.list.d/kopia.list
sudo apt update

By default, the stable channel provides official stable releases. If you prefer you can also select testing channel (which also provides release candidates and is generally stable) or unstable which includes all latest changes, but may not be stable.

Finally, install Kopia or KopiaUI:

sudo apt install kopia
sudo apt install kopia-ui

The fixation with using sudo when you want to do something as root has its merits, but the moment you have to pipe commands together, things can go wrong very quickly. So, bite the bullet and for this installation forget about sudo and do everything as root.

If you have not set a root password, then instead of running su -, run sudo su - as the first step below, in which I have left blank lines to show what is actually one-line commands:

su -

curl -s https://kopia.io/signing-key | gpg --dearmor -o /etc/apt/keyrings/kopia-keyring.gpg

echo "deb [signed-by=/etc/apt/keyrings/kopia-keyring.gpg] http://packages.kopia.io/apt/ stable main" | tee /etc/apt/sources.list.d/kopia.list

apt update

apt install kopia kopia-ui

logout

The above is a copy & paste from my notes and is how I install Kopia on Debian based distributions. If Ubuntu is a special case, then yes, it is a special case, and ask on an Ubunbtu forum how to change things from stock Debian.

At a glance it seems to look correct for .deb-based linux dists, what part are you thinking will not work?

4

Yeah those instructions don’t work in modern Ubuntu. One easy way to install kopia in ubuntu is using deb-get

ERROR! kopiaui is not a supported application.
deb-get

deb-get installed fine. Still having problems. Maybe Linux needs top work harder at making things easier for developers? Cuz I can see why a developer might wish to walk away. Not worth the squeeze.

6

Know the process for getting Ubuntu to support this in their software store? Because the old version they have posted installs easily. Maybe getting Ubuntu to figure out this nonsense is really the way forward?

7

just missing a hyphen
$ deb-get install kopia-ui
you can see all the apps with
$ deb-get list

Didn’t get your tip in time, and don’t really know how I did it. But it’s related to something here: apt key - Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead - Stack Overflow

In any case, I accidentally installed a full V.19 package in parallel to my old installation. It recognized the old repository instantly and I think I’m in business.
