I’m using Neovim 0.5 in an ssh connection with X11 enabled.
When I try to yank text to the clipboard the following error is printed in the status line:
clipboard: error invoking xsel: /usr/bin/xsel: BadAccess (attempt to access private resource denied): Resource temporarily unavailable
However, xsel does work when invoked from the shell. E.g:
> xsel text in clipboard%
The server is running Ubuntu 18.04.5 LTS (GNU/Linux 4.15.0-140-generic x86_64).
The xsel version is 1.2.0.
Any help to fix this would be very much appreciated.
EDIT: Somebody reported a similar issue here to which someone responded: “does xsel also have the same issue outside nvim? Then it is not nvim bug. I would guess some kind of xauth problem with ssh X11 forwarding.” I’m not familiar with xauth. If anybody could expand on this I would really appreciate it.
EDIT 2: I investigated a bit further and it seems to be a problem with xsel’s CLIPBOARD selection (which is the same unnamedplus register in nvim). I suspect that it does not work on the server probably because the administrator disabled it. The PRIMARY selection does work fine though.
