roudcube upgrade fails

Unattended-upgrades of Debian12 Bookworm fails while processing roundcube. The following error is reported:

Code:

INFO: Running /usr/share/roundcube/bin/update.sh as user 'www-data'
PHP Parse error:  syntax error, unexpected '|', expecting ';' or '{' in /usr/share/roundcube/program/lib/Roundcube/rcube_utils.php on line 431
Fatal error: Please check the Roundcube error log and/or server error logs for more information.

Any insights on how to correct this ?

 

What shows command

Code:

apt policy roundcube

What is in line 431 of that file /usr/share/roundcube/program/lib/Roundcube/rcube_utils.php ? Show two or three lines before and after that line.
What is in /var/log/dpkg.log and unatted-upgrades log?

 

The code is :

Code:

    /**
     * Converts a human readable IP address to its packed in_addr representation
     * Like the builtin inet_pton() function, but fallback to
     * inet_aton(3)-behavior for IPv4.
     *
     * @param string $ip    A human readable IPv4 or IPv6 address.
     *
     * @return string|false
     */
    public static function inet_pton2(string $ip) : string|bool {
        $address = @inet_pton($ip);
        if (is_string($address)) {
            return $address;
        }

/var/log/dkpg.log is terse on the subject:

Code:

2026-06-01 06:51:16 configure roundcube-core:all 1.6.5+dfsg-1+deb12u9 <none>

OK, I have found that PHP 8.5 CLI is on the system, but it does not have all the extensions. How can I know which ones are required ? (The only one I have installed explicitly is soap)

Is there a risk to break existing packages ???

 

OK, thx. Change to 8.2 made. Will report if more/new problems emerge
