------- Comment From cborn...@de.ibm.com 2019-09-03 14:58 EDT------- This still has the verification-needed-xenial tag. Will this be backported or can we remove that tag? xenial-proposed does not seem to contain a kernel update and a backport to xenial was not requested. (It would be possible though).
