Segmentation Fault

I've tried installing DigiDoc4-Client by modifiying the install-open-eid.sh script to include Kali Linux but that causes the following error when starting qdigidoc4 via CLI:

Chache configuration serial: 157
Bundled configuration serial: 160
Bundled configuration is recent than cache, resetting cache
QObject: Cannot create children for a parent that is in a different thread.

This issue also replicates when DigiDoc4-Client is also built from the source.

$ uname -a

In theory, open-eid and its components should work in Kali, as it's Debian based (although it's Debian Testing).

The libxml-security-c package is from where? seems like somekind openssl version mismatch ? 3.0 vs 3.1?

[Arszilla]

Currently, libxml-security-c20 is installed, which has the following info:

You can try lunar packages https://installer.id.ee/media/ubuntu/dists/lunar/main/binary-amd64/Packages and second we distribute xml-security-c compiled with xalan-c support

I was having the same issue under KDE Neon 5.27 (Ubuntu 22.04). I used also the ie.ee install script. I was about to manually build myself, but then the first 2 steps in the readme did the trick. In particular:

curl https://installer.id.ee/media/install-scripts/C6C83D68.pub | gpg --dearmor | tee /etc/apt/trusted.gpg.d/ria-repository.gpg > /dev/null
echo "deb http://installer.id.ee/media/ubuntu/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/ria-repository.list
sudo apt update

sudo apt install cmake qt6-tools-dev libqt6core5compat6-dev libqt6svg6-dev libpcsclite-dev libssl-dev libdigidocpp-dev libldap2-dev gettext pkg-config

Closing due inactivity, reopen if needed.

With the changes introduced in https://github.com/open-eid/linux-installer/pull/120, this issue cannot be reproduced any further.
