I can confirm that it doesn't work with 5.2.0-050200rc7-generic #201906300430 SMP Sun Jun 30 04:32:31 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux.

Had it work with https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959 in the 4.18 kernel though, though I still haven't made it connect to protected networks.

Was able to make it work with 5.2-rc7 kernel with this repo: https://github.com/EntropicEffect/rtl8822bu with this patch: https://github.com/EntropicEffect/rtl8822bu/commit/70d7b10a2eafdbf36ee64790646d74b5baf3a807.diff and it's connecting with protected/secure networks unlike the other repo.
