i think while moving from Ubuntu 16.04 to 18.04 you have also updated the PHP (e.g. from PHP 5.6 to 7.0) but missed to make sure that all previously PHP extensions of 5.6 are also installed for 7.0.

God idea tom42,
curl extention looks installed for both php.7.0 and php.7.2:
user@host: locate mods-available | grep -i curl

then I tried to:
sudo phpenmod curl
sudo service apache2 restart

But curl looks to owncloud server stll as not installed.
If you known some other procedure to follow, you will be welcome.


maybe you could ask in an Ubuntu forums or the support of your hoster how to correctly migrate a PHP installation so that the required modules are correctly enabled and provided to PHP applications like ownCloud?

I agree with @tom42, that this is highly off-topic.
