I have an AppImage from Creality which segfaults with a QT ssl

omits some X509 functionality, which can be found in OpenSSL-1.1.
(And someone reports that installing it solves the problem.) But I
can't find that package. Is there any way to revert to an earlier
version of OpenSSL? I'm on an up-to-date bookworm system.
AppImages bundle all the libraries used by the application, so
changing the "system" version of openssl probably won't work.
It sounds like you need to contact Creality to update the AppImage.
Although
https://forum.manjaro.org/t/creality-slicer-appimage-not-loading-qt-network-ssl-errors/143726
suggests that the AppImage does not contain the OpenSSL library.
But the only 'omission' of X.509 functionality that I can see on
https://www.openssl.org/news/openssl-3.0-notes.html is
"X509 certificates signed using SHA1 are no longer allowed at security
level 1 or higher. The default security level for TLS is 1, so
certificates signed using SHA1 are by default no longer trusted to
authenticate servers or clients."
I'm not sure I'd want to be deliberately trying to undo a security
upgrade.
I'm sure you're right. Contacting Creality is a fool's game; they've been
alerted to the problem since they released the software, so I'll just have
to be patient.
Contacting Creality with a problem also nullify's any warranty you may
have thought you had. I replaced a broken plastic ejector on an E5+ with
the exact same item made of metal, from the same injection dies that
made the plastic one and that they sell. The first thing they did was
cancel the warranty on that serial number because it was a non-stock
part I had installed. They would have a cow if they knew what I'm doing
to it now.
However, An E5-S1 is the best small sub $600 printer ever. On its 3rd
roll of PETG now, its slinging great parts at me. Minor adjustments of
course but it Just Works.
Thanks to all for your suggestions.
Patrick
