QCAD can read/write DWG files on Linux, it costs just 40 bucks, and it has an autocad-like interface. But if your instructor says that they need autocad, better keep a Windows machine too.
Another way to read/write DWG files is to download and make executable the appimage here. It converts DWG to DXF. https://www.opendesign.com/guestfiles/oda_file_converter Then you can load the DXF on the Community (Free) version of QCad.
Sure, you could load that DXF file on any Linux app (e.g. librecad, freecad), but qcad is the most autocad-like app of them all. Even Librecad is a very, very old fork of qcad, which hasn’t progressed much since. https://qcad.org/en/ You can make their trial version of QCAD (that supports natively dwg) to become free community edition by removing some library files they request on their UI. The ability to read dwg goes away, but then you have the converter above to do the job.



Mint is very, very stable. However, not all hardware is compatible, especially since Mint is using older libraries. For most people, Mint is the best solution. For your hardware, it seems to be Debian-Unstable. I personally use both and I’m happy with both.
