Comment 8 for bug 2064492

Thank you, so here we go:

> execve("/usr/lib/aarch64-linux-gnu/qt5/libexec/QtWebEngineProcess", ["/usr/lib/aarch64-linux-gnu/qt5/l"..., "--type=zygote", "--disable-in-process-stack-trace"..., "--application-name=akregator", "--webengine-schemes=qrc:sLV", "--lang=de"], 0xc5a2432bb180 /* 70 vars */) = -1 EPERM (Vorgang nicht zulässig)

This may be because of AppArmor restrictions. Can you try to disable AppArmor using these commands and see if it helps?

sudo sysctl -w kernel.apparmor_restrict_unprivileged_unconfined=0
sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

To re-enable it back, you can use the same commands but with 1 instead of 0.
