I am having problems using the USB ports on my Acer Aspire one. I have download the USBview app and when open it I get the following error:
Invalid desktop entry file: /usr/share/applications/usbview.desktop
I am using ubuntu 16.04.
It looks as though USBView installs the desktop file for Ubuntu 17.10 running Wayland as it tries to run a command sudo-to-root that is not compatible with Ubuntu 16.04.
Try installing gksu for GTK sudo.
sudo apt install gksu
Then copy and paste the following line to update the Desktop File:
sudo bash -c 'sed -i "s/sudo-to-root -X -c/gksudo/" /usr/share/applications/usbview.desktop'
Hope this helps!
