Similar to https://bugzilla.redhat.com/show_bug.cgi?id=2071843, Nextcloud 25 server is unusable in the Fedora 38 beta due to F38 shipping a newer version of PHP than Nextcloud can use. The lowest version of PHP available from the "fedora" repo is 8.2.2: php-fpm-8.2.2-1.fc38.x86_64 but Nextcloud 25 is not compatible with PHP >= 8.2: https://github.com/nextcloud/server/blob/stable25/lib/versioncheck.php#L36
https://bugzilla.redhat.com/show_bug.cgi?id=2071843 has been kept updated to track newer Fedora versions, so closing this as a duplicate. *** This bug has been marked as a duplicate of bug 2071843 ***
