KeepassXC 2.5.4 on Ubuntu 18.04 from Snap can't execute xclip

[argvi]

Overview

keepassxc.cli is unable to start xclip when attempting "keeppassxc.cli clip ...". was installed using apt, keepassxc is installed using snap. I believe it might have something to do with snap confinement.

Steps to Reproduce

1. snap install keepassxc
2. sudo apt install xclip
3. keepassxc.cli clip <kdbx_path> <entry_path> <timeout>

Actual Behavior

"Unable to start program xclip"

We would have to install xclip into our snap.

You could make the snap a "classic" snap which removes most of the confinement allowing it to execute xclip

[droidmonkey]

That totally defeats the purpose of being a snap

We would have to install xclip into our snap.

I got it to work by adding xclip to parts.keepassxc.stage-packages and adding the x11 plug to apps.cli.plugs
