I think given that verification is going to be slightly fiddly and the update is already badly overdue, I will not attempt to fix this bug in the next focal update. But also I do not want to leave it so long again until the next update. -- You received this bug notification because you are a memb

Just wondering if there's a plan or desire to (correct me if I use the wrong terminology here..) SRU this into bionic/focal? The criteria for SRU, from what I read, seem to be related to "critical bugs" (of which maybe this is not), "regressions" (which this isn't), and "hardware enablement" (whic
