Getting the most recent releases of gcc / g++ (11.0 or 10.2) on Ubuntu 20.04 LTS

Question

I'd like to get the latest releases of g++ (and clang) via package manager (apt). Currently I need to compile gcc/g++ on my own which needs really a lot of time.

Are there any repositories with "special packages" like g++-10-2, g++-11 or just g++-master?

I'd be really nice :-)

Does this answer your question? Why don't the Ubuntu repositories have the latest versions of software? — N0rbert, Jul 24 '20 at 17:13
Thanks for your answer. In general it is a good way to go. But because I'm developer who uses C++20 features I'd like to get latest releases (for my dev). For me it would be okay to add "beta" or "dev" repositories (called PPA). I know such software can contain new not fixed bugs... — Bernd, Jul 24 '20 at 17:21
I did already: sudo add-apt-repository ppa:ubuntu-toolchain-r/test — Bernd, Jul 24 '20 at 17:21
I would like to get a "developers' PPA" or "Ubuntu+1 repositories" — Bernd, Jul 24 '20 at 17:34
Actually these Linux systems are in virtual environment and used only to compile C++ - so I don't care about system stability or whatever... — Bernd, Jul 24 '20 at 17:41
The "dev" release of Ubuntu is currently 20.10, not 20.04. It will be released in October 2020. 20.04 has no "dev" repositories since it's already released. — user535733, Jul 24 '20 at 17:43
Is it possible to update ubuntu to version 20.10 (I use WSL - which has only 20.04)? In the answeres linked by N0rbert I found some nice tool "Homebrew", I'll check it... — Bernd, Jul 24 '20 at 17:54

There seems to be no way to get up-to-date packages for ubuntu, you have to built them by yourself...

There is a solution via ppa.

You can find the instructions here: Install g++ 11 on Ubuntu 20.04
