Hi Eli,

1.- Open zip archive in remote machine using TRAMP
2.- Modify archive member
3.- Try to save with Ctrl-x Ctrl-s

Will work w/o problems on locally edited archive

I can reproduce it. There seems to be an error in arc-mode.el. I'll
debug it when time permits; however, this mode is terra incognita for
me.

Or somebody who knows arc-mode.el could debug.

I only know how it works with local archives, not with remote ones.

Yes. But from my short debug cycle I've tried just now it looks, like
arc-mode detects that the zip file couldn't be edited directly, and it
works over a local temporary copy of that zip file. So it couldn't be
too hard to fix this, once we (I?) understand the different steps.

In order to make it clear, I transform this report into a wishlist.
Editing remote zip files hasn't been offered ever I believe.

Best regards, Michael.
