I've just installed the composer package into a clean 18.04 VM and I can run composer install, composer --version etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768023 Title: Composer fails to run with PHP Fatal Error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/composer/+bug/1768023/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
