You don't seem to understand what I said: I DO HAVE 4.15.0 installed (linux-generic-hwe-16.04): https://packages.ubuntu.com/search?keywords=linux-generic-hwe-16.04&searchon=names&suite=xenial-updates§ion=all
running 'apt-get install -t xenial-proposed linux-generic-hwe-16.04' does NOT pull any new/updated 4.15.0 kernel from xenial-proposed. To double check that I configured xenial-proposed correctly, I installed linux-generic, wich DOES have an update waiting (4.4.0-143 in xenial- proposed over 4.4.0-142 from xenial/main): -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813873 Title: Userspace break as a result of missing patch backport To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
