I have a problem while I tried to start symfony, the error is:
composer require server --dev
Some Symfony Flex features may not work as expected: your version of Composer is too old
Please upgrade using https://getcomposer.org/
I tried to update composer, but I can't find the way to do it, in composer documentation here I followed the steps but:
php -r "if (hash_file('SHA384', 'composer-setup.php') === '52cb7bbbaee720471e3b34c8ae6db53a38f0b759c06078a80080db739e4dcab6') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
Installer corrupt
So, I'm in a loop of errors, what can I do?
(I'm working in ubuntu)
Of course I tried:
composer self-update
[InvalidArgumentException]
Command "self-update" is not defined.

The command self-update
i only available when you install composer as a phar, not as a dependency in the global project or via apt.
So you need to uninstall composer
and reinstall it with phar and after you can use self-update
