We are running a self-hosted Passbolt-ce server running on Ubuntu 22.04.
Our current version is v4.8.0. The latest release came out last month, so I wanted to upgrade to the newest version. (so, from v4.8.0 to v4.8.2)
4.8.2 is only a release for the browser extension so no need to update your server for this one. You should have been automatically updated already. To confirm if you look at the bottom right corner when you are logged into passbolt you should see a small heart, if you hover over this it will let you know what version you have
