With distros, tzdata releases available depends how up to date the maintainers
keep the distro, and the package maintainers keep the tzdata package; which base
distro release you run e.g. 9 Stretch, 10 Buster; which repos you have available
on your selected mirror(s) and defined in your /etc/apt/sources.list e.g.
debian-updates, debian-proposed-updates, debian-backports,
debian-security/updates; although if a newer release is available for your
distro, the currently installed release should be able to be upgraded using your
preferred package manager e.g. as I have a package mirrors with debian-updates
repo available, and as I have added debian-updates repos to my package sources,
I am up to date:
$ apt list -a tzdata
tzdata/stable,stable,stable 2018g-0+deb9u1 all
$ sudo apt install tzdata=2018i-0+deb9u1
Reading package lists... Done
Building dependency tree
Reading state information... Done
tzdata is already the newest version (2018i-0+deb9u1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
SImilarly on Ubuntu 16.04 Xenial:
$ apt list -a tzdata
tzdata/xenial-updates,xenial-security 2018g-0ubuntu0.16.04 all
tzdata/xenial-updates,xenial-security 2016j-0ubuntu0.16.04 all
tzdata/xenial,xenial,xenial 2016d-0ubuntu0.16.04 all
where the base release is much older than Debian, and more recent distro release
18.04 Bionic is only at 2018d, and 18.10 Cosmic at 2018e. Other distros may
offer only older package releases e.g. Fedora whereas CentOS.
Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
