In composer.json the "repositories" item should look like this:
"repositories": [
{
"type": "composer",
"url": "https://plugins.roundcube.net"
}
],
Thanks Alec, this helped me get a bit further.
`php composer.phar update --no-dev` worked after your recommendation, installed and did many things.
Now when I go to my Roundcube installation I get this error:
Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 7.1.0".
Here is the output of
php -V on my system:
PHP 7.3.31-1~deb10u1 (cli) (built: Oct 24 2021 15:18:08) ( NTS )

Help! What am I missing here?
