I was editing a debian binary package (.deb). Finding the file opens it
in archive-mode, then finding the file 'data.tar.gz' opens it in
tar-mode. I proceeded to edit the file, which produced a warning message
reminding me to go and save the buffer for 'data.tar.gz'. However, when
I attempted to save the buffer for 'data.tar.gz', I got an error message
saying, "Symbol's value as variable is void: archive-ar-write-file-member".
I think this is because of a conflict between the hooks added to
'write-file-functions' by archive-mode and tar-mode. I notice this is
handled in archive-mode by this line in arc-mode.el:
(remove-hook 'write-contents-functions 'archive-write-file t))
which suggests that a similar fix might help in this case.
I am aware that it is better practice to simply regenerate the .deb
file, but this is a bug in Emacs nonetheless.

There might be such a conflict, indeed (I don't know how well tarballs
inside archives are handled), but arc-mode.el does not support writing
to ar archives anyway.

(I'm going through old bug reports that unfortunately got little response at
the time.)
I tried reproducing this in Emacs 28, but was unable to. Instead I got
various variations on
---
archive-*-write-file-member: Updating was unsuccessful (1)
---
which seems to be the correct response, since Emacs doesn't support
editing ar (i.e., .deb) files.
So I'm closing this bug report.
