[20.04.1] Uncooperative network center (more irritant than joy)

[Daniel LaSalle]

Ahhhh network center in GUI. So many reasons to love it. Here's a particularly basic one which surely would make my mom want NOT to use Linux:

Network connections -> Wired connection -> IPv4 settings -> Method: from Automatic(DHCP) to Manual + add address/netmask/gateway+dns server+SAVE = OK
ip a = specified IP address manually

Network connections -> Wired connection -> IPv4 settings -> Method: from Manual to Automatic(DHCP)+SAVE = OK
disconnect -> reconnect
ip a = same specified IP address manually!! But I was expecting to be leased a DHCP IP??

solution: Network connections -> Wired connection -> IPv4 settings -> delete manually added IP address + SAVE + disconnect + reconnect = ip a = DHCP IP, \o/

Food for thought: Thankfully I didn't have 6 different IP configurations in place.......................
