The pop_os subreddit has many Pop!_OS-specific help requests per day. I’m kind of surprised there aren’t more here on the Fediverse/lemmy side of the community.
I browse looking for ways to help, and after having shifted my attention from Reddit to the Fediverse I feel like I could be helping out more. Why aren’t there more requests here?
In any case, the Mattermost community is the best place to get support.
