I have an impression that ca-certificates on Ubuntu 16.04 LTS is outdated.

Today I tried to do:

sudo apt update
sudo apt-get install apt-transport-https ca-certificates -y

but none was updated:

Reading package lists... Done
Building dependency tree
Reading state information... Done
apt-transport-https is already the newest version (1.2.35).
ca-certificates is already the newest version (20210119~16.04.1).
0 upgraded, 0 newly installed, 0 to remove and 8 not upgraded.

Is my guess correct that Ubuntu 16.04 repository has outdated certificates?

If yes, how to install the latest ones?

(probably Git requires new certificates, see the full story here)

    Ubuntu 16.04 LTS has reached the end of it's standard support life thus is now off-topic here unless your question is specific to helping you move to a supported release of Ubuntu. Ubuntu 16.04 ESM support is available, but not on-topic here, see askubuntu.com/help/on-topic See also ubuntu.com/blog/…

  • Don't forget you're using a release that reached EOL for standard support back in April (5 years after release), so unless you enabled ESM, upgrades stopped months ago and so having no updates on a release that reached EOL surprises you? Only systems with ESM enabled receive updates now

If your system was upgraded you'd be using the following package

ca-certificates 20210119~16.04.1ubuntu0.1~esm1

But you've not updated your Ubuntu 16.04 LTS system, even though support ended in April 2021. Why are you surprised?

If you want to continue using Ubuntu 16.04 ESM, enable ESM and get the upgraded packages.

Ubuntu 16.04 LTS however is off-topic here. Please refer https://askubuntu.com/help/on-topic and you'll see only supported (standard or public) releases of Ubuntu are on-topic here.

    FYI: the package update/link I provided may not be the latest, I only looked for a notice of an upgrade for 16.04; and that was the first I found.
