[shadchen and lsp-mode] (was: [partially solved])

> Any chance you're running a somewhat old AUCTeX version?

I checked this now. Auctex in which version whatsoever is not the
culprit. Neither is it my init file, the only candidates I found are 
the lsp-mode and the shadchen mode that are installed in my .emacs.d (by
dependencies) I am unable to uninstall these packages.

I tried to upgrade them lsp-mode did not even compile all its file with
GNU emacs (master from November 2020).

So I now puzzled? Shall I ignore these error message?
How can I uninstall those packages?
