Hi there,
I tried installing the community package on my Ubuntu 21.10 but I have the following error when performing Step 3:
E: Unable to locate passbolt-ce-server package
(translated)
I did have a look at this Ubuntu 20.04 - Unable to locate package passbolt ce server but step 4 disappeared from the installation guide 
Any ideas?
Hi @James69
and welcome to passbolt community forum 
Installation guide is for Ubuntu LTS 20.04. As Ubuntu 21.04 is not a LTS version there is no package available for this version.
You should setup an Ubuntu 20.04 instead.
Cheers,
Thanks @AnatomicJC
Any chance of seeing an Ubuntu 21 or 22 anytime soon?
Hi,
There wonβt be any release for 21 as it is not a LTS version.
There will be a 22 version but there is no ETA for now.
In my opinion the easiest and safest way for you is to use docker, it works everywhere: Passbolt Help | Docker passbolt installation
Cheers,
