@Linux_in_a_Bit At least over here in Germany, there are dozens of dedicated Linux User Groups as well as most Hackerspaces offering public meetings and sometimes online communities. Many of these groups welcome guests and are usually happy to help with issues or at least know where additional help is available. I would assume other countries have a similar community. They’re definitely worth a try.
