I just installed it on a TGR1900 Onhub, Three google wifi and an X86. Used Attended Sysupgrade. On onehub everything went well. The three google wifi without connectivity via Luci and also via SSH. They continue to work, including the mesh, but without access.
X86 failed to generate firmware due to the following error:
STDERR:
