Would be great if it could get fixed, since this often results in errors in shared hosting environments and requires manual intervention.

From Nextcloud 11.0.2 --> 11.0.3 results in the same error.

SplFileInfo::isDir(): open_basedir restriction in effect. File(/var/www/cloud.foobar.org/www/updater/../..) is not within the allowed path(s): (/var/www/cloud.foobar.org/www/:/var/www/cloud.foobar.org/tmp/:/usr/share/php:/tmp/:/dev/urandom:/var/www/cloud.foobar.org/oc_data/)

This is fixed with the updater that is shipped in 12: nextcloud/updater#105

I will now backport this to the stable branches as well. Beside that you could also fetch the updater.phar and index.php from the github repo that is linked above and place them in the updater/ directory

The problem always occurs in NextCloud 9.

I tried to replace updater/index.php and download the updater.phar file into updater folder, but got the following error after the "download" step:
