One year later (well, roughly), and Peppermint 7, same bug, happens only
sometimes, after logging in, doesn't matter whether it's from a suspended
session, or logged out fully, even after a complete reboot;
sometimes nm-applet loads without any error, sometimes it displays:
(nm-applet:2962): nm-applet-CRITICAL **: get_menu_item_for_ap: assertion
'dup_data.hash != NULL' failed
Any chance somebody has a fix for this ? I don't mind if it's an
unofficial fix, as long as it works. It delays my work a lot, and I'd
really like to fix this somehow.
Thank you

Title:
Network manager applet unable to control wifi after suspend in 16.04
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
After resume from suspend network manager no longer allows me to
control my wifi card, view available wireless networks, or select new
ones. Oddly enough, I'm still able to communicate on the network that
I was connected to prior to suspend.
Running
# sudo service network-manager restart
resolves the issue until the next suspend/resume.
I'll copy what I think is the relevant portion of syslog below
