I was able to create a wifi hotspot on my debian 8 install using network tab under gnome settings. I was trying to do the same using nmcli but it always shows

$nmcli con up id Hotspot

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.

Welcome to Stackexchange! On my machine, I need to run nmcli con up id with sudo. Maybe that helps.

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.service

After that, I can connect again:

nmcli con up id 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.
