Dear K
I tried to flash the recovery, but it wouldn't read the file.
Then I remembered what you taught me about changing the directory.
I thought, " Could it hurt to cd into Downloads to tell it where the file is ? "
I ran the CLI command and it flashed the recovery no problem.
The same with the adb sideload.
And now I have LOS4MG on my S4.
Thanks for taking the time to help me.

Dear K
I found I do have pip3. I installed pyasn1 using pip3.
I tried again, and got an error message. This time I needed rsa. Which I installed using pip3.
I typed python3 update-verifier.py etc.....
In reply it showed
verified successfully
Thankyou very much for taking the time to help me.

Dear K
I changed the directory as you instructed.
Afterwards, in the CLI, I typed pwd and hit enter.
In reply it showed the path ending in update_verifier-master
I typed python3 update_verifier.py lineageos4microg_pubkey /Users/my user name/Downloads/lineage-18.1-20230614-microG-jfltexx.zip and hit enter
In reply it showed
Traceback (most recent call last): File "/Users/my user name/Downloads/update_verifier-master/update_verifier.py", line 6, in from pyasn1.codec.der.decoder import decode as der_decoder ModuleNotFoundError: No module named 'pyasn1'
Did I do something wrong ?
Dear K
I opened the Terminal and typed python3 and hit return and saw something like what you have written above, so it seems I have successfully installed Python3, thankyou.
I went to https://github.com/lineageos4microg/update_verifier and clicked the green code button. I clicked on Download Zip. update_verifier-master.zip appeared in my Downloads. I double clicked on this and a blue folder titled update_verifier-master appeared.
I think the next step is to Open the Terminal again and cd into that folder.
BUT I am stuck at this point because I don't know what "cd into that folder" means, or how to do it.
Could you elucidate ?
Yours sincerely ROMMMELLL
Thanks I.
I haven't done anything to the stock set up yet. I am just about to start.
Thanks for the tips.
Thanks K. That makes good sense. I will keep on reading.
Yes, https://wiki.lineageos.org/devices/jfltexx/install
I am following these instructions. (I should have included that in my Q.)
Dear K
Thankyou for the recommendation of Fennec.
I am finding this very useful.
