The only thing done, is that I manually replaced 1.19 to 1.20 by using commands in bash. may be something went wrong or I miss to do something while replacing 1.19 ?
Untar the file in a new directory and see which files are in the original directory to compare. If something is missing you know straight away.
Being an old IT person I have always compared files first before overwriting just in case having missed something. Use ls -la so you also see hidden files.
