bug#38404: 27.0.50; deleting files with ~ on the end with tramp did not work

[Jean Louis]

Deleting file /etc/courier/aliases/20191810~ did not work inside of
Tramp, there was "permission denied". But other files could be
deleted. I was root at the time and I could delete any file. When I
entered with ssh to system as root I could delete the file. With Tramp
it did not work.

I cannot repoduce it:

--8<---------------cut here---------------start------------->8---
# sudo touch /etc/touch~
# sudo ls -l /etc/touch~
-rw-r--r-- 1 root root 0 Nov 28 12:54 /etc/touch~
# emacs -Q --batch --eval '(delete-file "/ssh:|sudo::/etc/touch~")'
Password for /sudo:root@host: ********
# sudo ls -l /etc/touch~
ls: cannot access '/etc/touch~': No such file or directory
--8<---------------cut here---------------end--------------->8---

Does the problem also happen for you if you start "emacs -Q"? If yes,
could you pls reproduce it step by step, and show those steps? Pls set
also tramp-verbose to 6, andd show the resulting Tramp debug buffer.

Best regards, Michael.

I did it with ssh as root /ssh:root@example.com:/etc/some/file~

and I could not delete few files, even though permissions were 644

This doesn't tell me anything, sorry. Pls show the debug buffer.

RTFM :-)

In short:

- Apply (setq tramp-verbose 6)
- Rerun your test
- Send the resulting buffer *debug tramp/ssh root@host*, preferred as
  attachment

Best regards, Michael.

No answer for months. Well, w/o more information I must close the bug.

Best regards, Michael.
