I would be hesitant to put a squid proxy directly on the Internet as there is a history of vulnerabilities in that software and afaik a bunch of them are yet to be fixed.

First of all I would advise against trying to bypass the security controls your school implemented, but if I hypothetically would attempt to do what you’re trying I would probably set up a haproxy on a dedicated piece of hardware, such as a raspberry pi, and expose 443 to the Internet. I would configure a simple static website to serve as default, and add a ssh backend like in this guide: https://www.haproxy.com/blog/route-ssh-connections-with-haproxy

Now you can SSH to your backend by wrapping the connection with openssl s_client. From here you can do a dynamic port forwarding, which essentially acts as a socks proxy and finally connect to that with firefox

edit: slap a tls cert on that too for good measure. Helps with hiding the ssh traffic

Yeah it took a while for me to find as well, Debian moved to managing alot of packages you used to install with pip. In many cases you can just prefix pip packages with python3- and find them via apt.

apt install python3-certbot :)

This is true, they have however debated the issue and might loosen the restrictions:

TL;DR and for non-swedes: the suggestion argues that hobbyists should be allowed to use metal detectors more freely. The motion was initally approved by Riksdagen but later voted against as there already work in progress on matter of simplifying the rules regarding metal detectors. So change might come, hopefully sooner than later
