Fix copying to clipboard

[qubes-user-837]

Thanks for the cool project and very clear documentation.

While trying to get it working, I noticed that it took screenshots and moved them into the target VM perfectly, but didn't copy them to the clipboard. I tried debugging the qvm-run command manually, but eventually found the issue on this line

my $remotepath = "$ENV{HOME}/QubesIncoming/dom0/${filename}";

This should use ~ instead of $ENV{HOME}, as $ENV{HOME} evaluates to /home/[the dom0 username], but this doesn't necessarily exist in the target vm.

Example command that runs under qvm-run (typically with username "user"):

• xclip -sel c -t image/png /home/qubes-user/QubesIncoming/dom0/screenshot.png, vs
• xclip -sel c -t image/png ~/QubesIncoming/dom0/screenshot.png

With this change, it works. Hopefully this information can help others.

Command I used for testing

• xclip -sel c -o | file -
