bug#62180: A problem with Gnu or Linux or Google Drive

[Robert Boyer]

Here are some possibly related strangenesses with Emacs and Linux
on my Lenovo Chromebook while running Emacs.  Maybe my
real problem is with my internet provider Spectrum.

: time nice tar -czf foo.tar working --warning=no-file-shrank
tar: working/nqthm-1992/examples/basic/tmp.lisp: Read error at byte 0,
while reading 182 bytes: Input/output error
tar: working/nqthm-1992/examples/bronstein/bibo_exp.proofs: Read error at
byte 0, while reading 8704 bytes: Input/output error
tar: working/nqthm-1992/examples/flatau/app-c-d-e.lib: Read error at byte
0, while reading 7680 bytes: Input/output error
tar: working/nqthm-1992/examples/fm9001-piton/fm9001/list-rewrites.events:

Thanks,
