Trouble generating wifi hotspot in ubuntu 18.04
Hrushi
What happened was I wanted to change my WiFi hotspot default name, so I followed instructions as mentioned here. The following commands were written by me on the terminal:
sudo vim /etc/NetworkManager/system-connections/Hotspot
sudo systemctl restart NetworkManager
I changed the default name and password but now I am not able to generate my WiFi hotspot. Anyone help me out, please. My Ubuntu version is 18.04 and I have a wired network connection. It is perfectly fine even if I get the default hotspot name but I just need my hotspot running. I also restarted my laptop. Here is a screenshot of /etc/NetworkManager/system-connections/Hotspot file

If you create the Hotspot with the Network-Manager GUI, it creates the file /etc/NetworkManager/system-connections/Hotspot. In that file it is possible to edit the SSID and the password.
sudo vim /etc/NetworkManager/system-connections/Hotspot
The content of the file is:
[connection]
id=Hotspot
uuid=0bf627gd-8e34-48c6-865a-06f898b4y1hb
type=wifi
autoconnect=true
permissions=
secondaries=
[wifi]
hidden=false
mac-address=YOUR_WIFI_INTERFACE_MAC_ADDRESS
mac-address-blacklist=
mode=ap
seen-bssids=
ssid=SSID_NAME
[wifi-security]
group=ccmp;
key-mgmt=wpa-psk
pairwise=ccmp;
proto=rsn;
psk=YOUR_WIFI_AP_PASSWORD
[ipv4]
dns-search=
method=shared
[ipv6]
dns-search=
method=auto
To enable autostart you have to set the parameter autoconnect to true. Then restart your computer because the command: sudo systemctl restart NetworkManager for network restart seems not to work correctly.
After restart you can use the nmcli command to start the access point.
nmcli con up Hotspot ifname YOUR_WIFI_INTERFACE
YOUR_WIFI_INTERFACE you can find out with the command iwconfig.
Make sure you install network-manager and its dependencies to use nmcli.
