NoSQLBooster is a shell-centric GUI with a broad range of features that come with a paid license. The free tier is missing many of the features that make this GUI so great, like code completion and the visual query builder. NoSQLBooster does not work through a subscription model, so once you pay for a license, it’s yours forever (or until you want to update your version). - Source: dev.to / about 3 years ago

If you are using the version of pgadmin that can be downloaded from pgadmin.org, it does not list ubuntu 22.04 on it's list of supported distros. It likely depends on libraries or other dependencies that are not available anymore. Might want to see if you have any better luck if you install from source. Source: about 2 years ago

I will download pgadmin like you are suggesting and see if I can gather a few more details for my own understanding... Source: about 3 years ago
