For example Ubuntu 20.04 provides gcc-10 packages but it is still missing gcc-11. Both Ubuntu 21.04 and 21.10 provide gcc-11 packages. When does 20.04 get gcc-11? I am aware there are other ways to install gcc-11, but I am interested in finding out it's general availability in 20.04.

    Does this answer your question? Why don't the Ubuntu repositories have the latest versions of software? – guiverc Feb 27 '22 at 05:13
  • Not really, 20.04 provides gcc-10 over and above gcc-9. Question is more about how and when compiler packages with higher version make into the 20.04 repositories. @mchid answer is helpful in that it may never get a release. – Dr. Tenma Feb 27 '22 at 06:34

    Upgrades occur when security fixes are required; in most cases that means security patches are back-ported to existing packages - but there are rare exceptions where it's more work to backport fixes than to provide & fully QA-test the newer version; in which case the newer version will replace the older package. That has occurred twice thus for with focal (or 20.04); but it's rare. No-one has a crystal ball; but yeah it's unlikely security-flaws in gcc-9 will be that bad that it'll be replaced with gcc-10. – guiverc Feb 27 '22 at 06:37

When does 20.04 get gcc-11?

Probably never. For example, 20.04 has gcc-10 but 18.04 only has up to gcc-8.

In order to gain access to newer versions of gcc, the generally accepted method is to use the ubuntu-toolchain-r/test ppa:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
