Re: Bug Loading *.el.gz files into GNU/Linux Emacs.

[Davin Pearson]

Eli, I have found the source of the bug.

Somewhere in my explorations of Emacs I managed
to create a whole new directory tree:

/snap/emacs/1609/usr/share/emacs/28.1/lisp/

When I tried gunzip font-lock.el.gz it said
the following.

gzip: font-lock.el: Read-only file system

I tried chmod ing the /snap directory but
it failed with the following diagnostic:

$ chmod 777 /snap/
chmod: changing permissions of '/snap/': Operation not permitted

so it seems that the entire directory is mounted as read only.

Note that there is a file called font-lock.el.gz in the /snap folder (deeply
into the depths of the directory).

I can gunzip the file, but before I do so, I have to copy it to my ~/
directory
but as mentioned above, I cannot copy the file font-lock.el to the /snap
folder. (as the entire /snap directory is read only)

I hope you can give me some helpful advice!
