Error compiling for board AVR DB-series

It also says explicitly in the readme that it is supported, but the hyperlink leads to a 404 (https://github.com/SpenceKonde/DxCore/blob/master/megaavr/extras/DB28.md)

You haven't included the error, but my guess is that you haven't installed the -a version via board manager (windows/macos only) which included the updated compiler toolchain for the DB-series parts. I think I have a fix for the problem that kept linux toolchains from working, but haven't had a chance to implement it.

Missing documentation is known issue, gated by #44

Nope I downloaded the latest version from this repository - 1.2.0
Here's the error

Yes, this is expected, it is not supported with manual installations because the IDE does not include a compiler toolchain that supports this part. You must install 1.2.0-a (not supported for Linux) using board manager. Have been trying to get the Arduino team to roll a new official toolchain that will actually work for months now.
