I was able to create a Wi-Fi hotspot on my Debian 8 install using the network tab under Gnome settings. I was trying to do the same using nmcli but when I do

$ nmcli con up id Hotspot

it always shows

Error: Connection activation failed.

I'm trying to connect to the connection created by Gnome itself.

$ nmcli connection show

Hotspot 6db9bb0a-c61b-47fc-8ada-7ecd46873fc0 802-11-wireless --

I followed the steps from here.

I encountered this on Arch Linux 4.19.2 because wpa_supplicant and dhcpcd were running on my system.

The fix in my case was to end those programs and restart NetworkManager:

sudo pkill wpa_supplicant && sudo pkill dhcpcd
sudo systemctl restart NetworkManager

After that, I can connect again:

nmcli con up myNetwork

The complete error message was

Error: Connection activation failed: No suitable device found for this connection (device wlp3s0 not available because device is not available).

I think wicd also interferes with NetworkManager.
