Comment 3 for bug 1813068

Experiencing this same issue on bionic/linux-hwe-edge:

  amd64: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-bionic/bionic/amd64/r/rtl8812au/20190429_215013_0195c@/log.gz

  i386: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-bionic/bionic/i386/r/rtl8812au/20190429_215359_0195c@/log.gz

To fix this, I've backported patches from rtl8812au in disco to rtl8812au in bionic. No context changes were required.

Testing:

- Create Bionic 18.04 VM
- Install bionic/linux-hwe-edge kernel headers, image, and modules packages from -proposed: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+packages?field.name_filter=linux-hwe-edge&field.status_filter=published&field.series_filter=bionic
- Enable the -proposed repository in the VM
- "sudo apt update"
- Verify the version of rtl8812au-dkms is the one failing (found on this bug) "apt show rtl8812au-dkms"
- "sudo apt install rtl8812au-dkms", confirm it fails at installation step
- Uninstall "sudo apt remove rtl8812au-dkms"
- "pull-lp-sources rtl8812au bionic"
- Apply the debdiff, this will change a little depending on your cwd: "debdiff-apply < rtl8812au_4.3.8.12175.20140902+dfsg-0ubuntu8.1.debdiff"
- Build the package "debuild -us -uc"
- Install the .deb generated from the previous step
- Verify the package installs correctly "sudo dpkg --install rtl8812au-dkms_4.3.8.12175.20140902+dfsg-0ubuntu8.1_all.deb"
