uname is not used to report point release version number. The only authoritative files with point release details are: /etc/issue, /etc/issue.net, /etc/lsb-release, /etc/os-release
These are updated via base-files package - see https://launchpad.net/ubuntu/+source/base-files/9.4ubuntu4.5 base-files (9.4ubuntu4.5) xenial; urgency=medium * /etc/issue, /etc/issue.net, /etc/lsb-release, /etc/os-release: Bump version number to 16.04.3 in preparation for the point release. -- Adam Conrad <adcon...@ubuntu.com> Mon, 31 Jul 2017 07:36:56 -0600 The meaning of this version string is not to reflect point release version.
