<Solved>Error while updating the Arch/Parabola system

[Stellaris]

I am on Parabola GNU/Linux which I migrated from Arch linux and when I try to update the system, it shows below message.

sudo pacman -Syu

How can I fix this? TIA

Fixed.
libxfce4ui needs 4.16.0 version of xfce4-session. But uninstalled xfce4-session and installed new version again. It worked.

Apparently it did not work. Thunar stopped working, so I realised something was wrong with upstream.
Waited couple more days to update again. Then,

error: openssl signature from "Pierre Schmitz <[email protected]>" is marginal trust

This came up. Refresh your keys and you will be fine. (as root)

pacman-key --refresh-keys
