Add Qubes repositories to standalone HVM (missing public key)

[marti...@gmail.com]

Hi,

I'm trying to install qubes-* packages to a standalone Linux HVM to try benefit from clipboard, file transfer between qubes, etc.

I created the file /etc/apt/sources.list.d/qubes-r4.list and put in it the string that follows:

deb [arch=amd64] https://deb.qubes-os.org/r4.0/vm bullseye main

However, apt can't verify the signature of the repo.

My question is: what public key do I need to import to apt?

Thank you in advance,

Download the key from https://keys.qubes-os.org/keys

Then add to apt with

sudo apt-key add downloaded_key.asc
