/usr/bin/prime-select:BrokenPipeError:/usr/bin/prime-select@374:enable_profile:_disable_nvidia:_update_initramfs

[errors.ubuntu.com bug bridge]

[Impact]

 * The progress bar that is drawn to keep track of the update-initramfs process can result, sometimes, in a BrokenPipe error. In no way does this affect the final result of the actual operation, yet it causes the progress bar to crash.

[Test Plan]

 * Install the nvidia-prime package and , and then execute "sudo prime-select intel" so that NVIDIA can be disabled, and the update-initramfs command is called. This might need repeating (i.e. going back and forth from "sudo prime-select intel" to "sudo prime-select on-demand" until the BrokenPipe error shows up.

[Where problems could occur]

 * This can cause no regression, since it does not alter the actual functioning on nvidia-prime, and the change has been in Impish since its release.
