I just tried upgrading Roundcube from 1.5.3 to 1.6.0. the installto.sh script ran without errors. But when I then try to launch the Roundcube site, I get this error from apache:
[Thu Sep 08 16:40:48.460523 2022] [php7:error] [pid 140000] [client 192.168.1.2:61284] PHP Fatal error: require(): Failed opening required '/var/www/roundcube/vendor/composer/../symfony/polyfill-php72/bootstrap.php' (include_path='/var/www/roundcube/vendor/pear/auth_sasl:/var/www/roundcube/vendor/pear/console_getopt:/var/www/roundcube/vendor/pear/net_idna2:/var/www/roundcube/vendor/pear/net_ldap2:/var/www/roundcube/vendor/pear/net_socket:/var/www/roundcube/vendor/pear/pear_exception:/var/www/roundcube/vendor/pear/pear-core-minimal/src:/var/www/roundcube/vendor/pear/console_commandline:/var/www/roundcube/vendor/pear/mail_mime:/var/www/roundcube/vendor/pear/net_smtp:/var/www/roundcube/vendor/pear/crypt_gpg:/var/www/roundcube/program/lib:.:/usr/share/php') in /var/www/roundcube/vendor/composer/autoload_real.php on line 75
Apparently I am missing the file /var/www/roundcube/vendor/composer/../symfony/polyfill-php72/bootstrap.php
Where can I get it from?
What version of PHP are your running? 1.6.0 requires a minimum of 7.3
# php -v
PHP 7.4.3 (cli) (built: Aug 17 2022 13:29:56) ( NTS )
That should not be a problem, I hope.
I want to do the update, because I want to bring this machine to Ubuntu 22.04 - which comes with PHP 8. Before I do this, I'm trying to make sure my sites can play along well even with PHP 8. Roundcube is the last contestant.
Is your web server running the same PHP version? When you did the update did you run composer update as well?
Yes, the webserver runs in the same VM with the same PHP version. And yes, as suggested in the doc, I did run the composer update as well.
