Changing the repository doesn't help
Can you try adding this debug info? it could help me understand what could be going on there: diff --git a/libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp b/libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp index d6345e559..e98f992b0 100644 --- a/libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp +++ b/libdiscover/backends/FlatpakBackend/FlatpakBackend.cpp @@ -229,6 +229,7 @@ static FlatpakResource::Id idForComponent(const AppStream::Component &component) // app/app.getspace.Space/x86_64/stable const auto bundleId = component.bundle(AppStream::Bundle::KindFlatpak).id(); auto parts = bundleId.splitRef('/'); + qDebug() << "helloooo" << bundleId << parts; Q_ASSERT(parts.size() == 4); return {
After I updated apps manually using commands, the crash is gone. Will report again if Discover crashes again.
