Can you help me install clang-14 on Ubuntu 18.04? I think I need a valid repo as apt-get install clang-14 does not work.

$ cat /etc/issue
Ubuntu 18.04 LTS \n \l

$ sudo apt-get update

    Does this answer your question? [Why don't the Ubuntu repositories have the latest versions of software?](https://askubuntu.com/questions/151283/why-dont-the-ubuntu-repositories-have-the-latest-versions-of-software) – user535733 Jun 24 '22 at 17:45
  • Not tested from me. Can be dangerous. https://apt.llvm.org/ – nobody Jul 04 '22 at 18:25

wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
sudo ./llvm.sh 14

clang-14 is not available for your release ... but available as of Ubuntu 22.04

So, upgrading to 22.04 is what you might want to consider.

  • Thanks for the clarification! – SpeedChaser Jun 24 '22 at 16:52
  • Updating to Ubuntu 22.04 is not always possible. Both because there are a lot of performance downgrades that make it undesirable (snap everywhere, for example), but also because: on work servers, we can't just choose to upgrade, that's decided at a totally different organizational level. – James Feb 08 '23 at 18:54

You neded ubuntu-toolchain-r ppa in bionic

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

sudo apt update && sudo apt upgrade

wget https://apt.llvm.org/llvm.sh

chmod +x llvm.sh

sudo ./llvm.sh 14

And now are installed with clang-14 and clang++-14 .
