libcurl3 error

[viastgg]

Hello
I am getting an error while running futurerestore.

./futurerestore_linux: /lib/x86_64-linux-gnu/libcurl.so.4: version CURL_OPENSSL_3' not found (required by ./futurerestore_linux)`

I have libcurl4 but the libcurl3 deb package is in the downloads folder.
But some dependencies are conflicting while downloading libcurl3.

The following packages have unmet dependencies:
   libcurl3 : Dependencies: libldap-2.4-2 (>= 2.4.7) but not installable
   pop-desktop : Dependencies: gnome-control-center but won't install
                 Dependencies: curl
                 Dependencies: gvfs-backends
                 Dependencies: pop-upgrade but won't install
                 They recommend: io.elementary.sideload but not installable
                 They recommend: simple-scan but it won't install
E: Error pkgProblemResolver::Resolve caused corrupted packages, which may be caused by retained packages.

what can i do?
