I'm not an expert with RPI and Linux but I also think that the problem
here is on the SD card.
This should also be confirmed by the errors I found with df -h (ref. my
post today at 17:03 and the comment by @Dennis Lee Bieber)
But as you've always read in one of today's posts, @The Natural
Philosopher is not our opinion.

RECOMMENDATION FOR THOSE POSTING FOR THE FIRST TIME HERE
The thread has now become complicated to follow ..... I invite those
who want to post for the first time to carefully analyze ALL the posts,
otherwise it generates even more confusion.
Thank you
