Security News > 2022 > February > Ubuntu applies security fixes for all versions back to 14.04

Ubuntu has issued a batch of updates that cover the default as well as the AWS and KVM flavours for the current short-term release 21.10, both the original 5.04 and OEM 5.14 builds for the current 20.04 LTS release, as well as 18.04, and, surprisingly, even 16.04 and 14.04.

While kernel releases trickle out all the time, the last two members of that list - 2016's Xenial Xerus and 2014's Trusty Tahr - emphasise that even very old releases in Extended Security Maintenance or ESM sometimes need a bit of TLC. It also might surprise some that multiple different Linux kernels are available for a single product release.

Although Ubuntu pushes out a new Long-Term Support release every even-numbered year, those get five years of bugfixes.

If you run an LTS release but you need features from newer releases, there are two ways forward.

If there's a newer LTS release, upgrade to that - but maybe play it safe and wait for the point-one release, as with any OS. For instance, for 20.04, 20.04.1 arrived the following August.

Sudo -s apt update ; apt full-upgrade -y ; apt autoremove -y ; apt purge ; apt clean ; snap refresh.
