I'm afraid that linuxdeploy https://github.com/linuxdeploy/linuxdeploy-plugin-qt used by CI bundles libssl.1.1 instead libssl.3.0, anyway installing libssl.3.0 to the system should fix this, @paukert can you check it please?

https://learn.microsoft.com/en-us/windows/win32/com/schannel should help, Qt6 provides qschanel plugin

As far as I know I have not manually installed OpenSSL 3 on my system before. Import & Sync from/with ORIS is working despite messages in log (see first post of this issue).

Even if I installed OpenSSL 3.1.2, the error is still shown in the log.

I'm not sure, whether marked libraries are not used by postgres.
