[horde] Call to undefined function Sabre\HTTP

[Simon B]

Hallo,

Since years I have not updated horde or the debian version of the server
and today I received a strange error..

A fatal error has occurred
Call to undefined function Sabre\HTTP\curl_init()
in /usr/share/2020-git-horde/Dav/bundle/vendor/sabre/http/lib/Client.php:333

1. Horde_ErrorHandler::catchFatalError()

Details
The full error message is logged in Horde's log file, and is shown below
only to administrators. Non-administrative users will not see error details.

ErrorException Object
(
    [message:protected] => Call to undefined function Sabre\HTTP\curl_init()
    [string:Exception:private] =>
    [code:protected] => 0
    [file:protected] =>

                (
                    [function] => catchFatalError
                    [class] => Horde_ErrorHandler
                    [type] => ::
                    [args] => Array
                        (
                        )

                )

        )

    [previous:Exception:private] =>
    [severity:protected] => 1
    [logged] => 1
)

All users receive this error.

Logging into /imp or /kronolith URLs does not produce the error.

Any idea where to look? Apache was restarted a week ago, so I don't think
it is related to that.


Thanks.

Simon
