I am just trying my luck here with an issue that i have been unable to
resolve on my Qubes system for a long time now. I have been looking
into this problem quite a bit but i cannot seem to find a solution
anywhere. Perhaps someone on this list has experienced the same and
has found a solution.
When i open a text file that is located on a network share with gedit,
gedit is unable to save the file. When I click the save button, or
`Ctrl + s`, i can see gedit creates a temporary file named
".goutputstream-AO9U51" on the network share and in gedit i get a
message "Could not create a backup file while saving
"/home/user/data/test/file-name.txt"". If i launch gedit from cli i
see a message on cli when saving the file "Hit unhandled case 27
(Error renaming temporary file: Resource temporarily unavailable) in
parse_error."
I definitely have permissions on the network share as i can copy files
to it, delete, create directories, etc. I can also open a LibreOffice
document and save it. The problem appears to be specific to gedit.
Also, it happens with both a Fedora and Debian based VM.
In addition that i forgot to mention is, i can open edit and save the
same txt files with vi and it works.
I have read reports [1][2][3][4][6] dating as far back as 12 years with
the sshfs protocol (an abandoned project) being implicated as well.
On issue 438 [3] that was reported on Gitlab it is reported that "As far
as I can tell, the problem is in the way glib saves a file by writing to
a temporary file and renaming to the final name." and "I'll take a more
serious look later but I'd start with gio/glocalfileoutputstream.c and
particularly the function _g_local_file_output_stream_really_close which
contains the error string "Error renaming temporary file".".
A duplicate issue 565 [5] to issue 438 [3] was opened and there a patch
is provided that is said to fix this issue although i have not tried it
because i don't know how to.
**Question:** Would anybody perhaps know how and where to do the patch,
attached for reference, on Fedora/Debian. As far as I can tell the patch
needs to be done on the client since the problem originates from the client.

Subject: [PATCH] gio: workaround for renaming files on filesystems not
supporting it
This is a workaround for samba and "Virtual Box shared" filesystem which does not support renaming opened files and react on such attempt with ETXTBSY. It is also a solution proposal for:
Bug 678994 - Unable to overwrite files on vbox shared mounted filesystems
