tmn505 [1] filed a deletion request for mt76-git [2]: Almost all changes that land in https://github.com/openwrt/mt76 are submitted upstream. Drop this package as any commit in upstream repository can break compilation of modules with stable kernel or lts kernel. For most users wanting to test the latest development of these drivers, I suggest using linux-next-git, which is pretty up-to-date with mt76 changes or slightly delayed linux-git. For LTS kernel users, I suggest using latest linux backports (https://backports.wiki.kernel.org/index.php/Main_Page).
