gparted-1.4.0-1 lacks the firmware needed to run on Realtek network cards
My computer has a Gigabyte DS3H motherboard which includes a network chip from Realtek: 04:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c) Subsystem: Gigabyte Technology Co., Ltd Onboard Ethernet [1458:e000]
It can happily be used in any linux distro but gparted-1.4.0-1 cannot use it because it does not include the mandatory firmware that is needed . Instead the kernel reports:
failed to load rtl_nic/rtl8168g-2.fw
A quick google search suggests including the package firmware-realtek in order to solve the problem.
