Hi! Suddenly, lkb mode in emacs ceased to work. When I enter “M x lkb”, I get the following message:
Package cl is deprecated
Lkb mode is not loaded. This seems strange to me, because I didn’t change anything in my system (Ubuntu). I suspect the error is caused by the fact that emacs was automatically updated to a new version:
GNU Emacs 28.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo version 1.16.0)
I would much appreciate any hints on how to solve this problem.
