install gcc-9 on Ubuntu 18.04?

Question

gcc-9 is just released.

I was wondering if there is a repository that allows me to install gcc 9 on Ubuntu 18.04 LTS (bionic)?

There seems to be repositories supporting disco:

https://packages.ubuntu.com/disco/gcc-9-base

But I liked to have it on the current LTS for a while.

It is now available in ubuntu-toolchain-r too:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-9

If the add-apt-repository command cannot be found, run this:

sudo apt install software-properties-common

Above commands install just c compiler, if you need c++ compiler (g++) too

sudo apt install g++-9

just as a reminder to people reading this sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-9 – JHBonarius Oct 25 '19 at 15:53

To make @JHBonarius 's useful comment complete, you need to install g++ along with gcc, i.e. sudo apt install gcc-9 g++-9 – user1507435 Feb 03 '20 at 23:02
@JHBonarius: What does your command do? – Tor Klingberg Apr 16 '20 at 12:42

@TorKlingberg, apt install gcc-9 g++-9 installs binaries with names gcc-9 and g++-9 in Ubuntu 18.04, if you want to use gcc & g++ then update-alternatives provides convenient way to do it. And if you have multiple different versions of gcc (and not just gcc) you can create alternatives for all of them and then easily switch between them. – ISanych Apr 16 '20 at 14:01
Not working on Bionic : ```The following packages have unmet dependencies: gcc-9-multilib : Depends: libc6-dev-i386 (>= 2.11) but it is not going to be installed Depends: libc6-dev-x32 (>= 2.11) but it is not going to be installed lib32gcc-9-dev : Depends: lib32gcc-s1 (>= 9.3.0-11ubuntu0~18.04.1) but it is not going to be installed (...) libx32gcc-9-dev : Depends: lib32gcc-s1 (>= 9.3.0-11ubuntu0~18.04.1) but it is not going to be installed (...)

@HenriquedeSousa, I've just tested it in docker, still installing fine. Either you have something else conflicting installed or something wrong with your packages db. – ISanych Nov 02 '20 at 15:35
Yep, I add to use aptitude to force the installation, then it worked. apt alone would not install it. – Henrique de Sousa Nov 02 '20 at 23:35
I upgraded my kernel to 5.3.0-050300-generic and VM multiplayer required this version of gcc, it worked like a charm! – Manuel Lazo Jan 11 '22 at 14:21

I used a search for PPAs, using search on launchpad.net and found JonathonF's GCC 9.0 PPA. You can install this package by:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:jonathonf/gcc
sudo apt-get update
sudo apt-get install gcc-9

Thanks for the clarification. I changed PPA to "repository" accordingly. – tinlyx May 03 '19 at 11:09
Edited my answer and removed info about PPAs and repositories (to be more neutral). – N0rbert May 03 '19 at 12:16

Note: you need to sudo apt-get update before the install. – EntangledLoops Sep 27 '19 at 22:29
@EntangledLoops Why? AFAIK, there is an automatic update after calling add-apt-repository. – Zheng Qu Feb 01 '20 at 11:59

@ZhengQu Yes, it appears that's another thing that changed in 18.04. I was running 16.04 at the time. – EntangledLoops Feb 01 '20 at 21:58
This command gives me Cannot add PPA: 'ppa:~jonathonf/ubuntu/gcc-9.0'. ERROR: '~jonathonf' user or team does not exist. Is this answer is out of date now? – Soylent Graham Jun 28 '20 at 15:30
Running sudo apt-get install software-properties-common before add-apt-repository ... fixed this. – Soylent Graham Jun 28 '20 at 15:48
I'm not sure what's happened in the past week, but deploying again, and gcc-9 seems to have gone missing (g++-9 still installs) – Soylent Graham Jul 05 '20 at 15:07
edit: I NEEDED to run sudo apt-get update after add-apt-repository on ubuntu 18.04.4 (Jetson nano) – Soylent Graham Jul 05 '20 at 15:13
This is no longer working, is there another source repository for this ? The user named '~jonathonf' has no PPA named 'ubuntu/gcc-9.0' Please choose from the following available PPAs: – Lenny D Jun 29 '21 at 10:49
Thanks, @LennyD . Answer updated. – N0rbert Jun 29 '21 at 16:23

This now gives me E: Unable to locate package gcc-9 on Debian GNU/Linux 10 (buster) – Soylent Graham Aug 16 '21 at 10:57
This is no longer working. Same output as @SoylentGraham. – pookie Oct 17 '21 at 13:54
Debian is off-topic here. Just tested on supported Ubuntu 18.04.6 LTS, all commands work normally; gcc version 9.2.1 20191109 (Ubuntu 9.2.1-19ubuntu1~18.04.york0). You should ask support for Debian on different site. – N0rbert Oct 17 '21 at 14:02
