Any info? Thanks.

I'm having the same issue. Are you also having the issue with wifi connecting and disconnecting multiple times and still no Internet?

[enamul-ssl]

same thing here.

Please try to delete /etc/create_ap.conf and rw install as a temporary fix

not working this way. then I tried this command: sudo create_ap wlp0s20f3 enp4s0 'kme' '12345678'

it gives this results:

Config dir: /tmp/create_ap.wlp0s20f3.conf.X9qkmbCK
PID: 8178
Network Manager found, set ap0 as unmanaged device... DONE
Creating a virtual WiFi interface... 

and get hang or loading

[bhavberi]

Yeah, I'm also facing the same issue after upgrading to Linux Mint 22. It was working fine in Linux Mint 21.

It gets stuck at the following stage:

[pcxz]

A workaround is:

1. launch command for start wi-hotspot
2. from bash execute: sudo systemctl restart NetworkManager sleep 5 sudo systemctl restart NetworkManager

After first restart is created ap0 After second restart is started hotspot

Why??

[pcxz]

And this is bugreport created from python. bugreport.txt

[Moini]

Subscribed, I see the same thing as @bhavberi on my Linux Mint 21.3.

[pcxz]

I sent a bugreport to "apparmor" gitlab. They said it's an old bug that's already patched, and probably not related to the wi-hotspot issue. https://gitlab.com/apparmor/apparmor/-/issues/424#note_2065922723

[pcxz]

SOLVED

Edit /etc/NetworkManager/conf.d/ubuntu-system-adjustments.conf and change line: unmanaged-devices=none in: #unmanaged-devices=none

[Kabouik]

A workaround is:

1. launch command for start wi-hotspot
2. from bash execute: sudo systemctl restart NetworkManager sleep 5 sudo systemctl restart NetworkManager

After first restart is created ap0 After second restart is started hotspot

Why??

So this works for me on Guix as opposed to just commenting out unmanaged-devices=none in /etc/NetworkManager/NetworkManager.conf, but I still lose Internet access from the WiFi I was connected to in the first place. Also, I can connect another device to ap0, but eventually I will get this:

Failed to set beacon parameters
ap0: INTERFACE-DISABLED 
ap0: INTERFACE-ENABLED 
ap0: INTERFACE-DISABLED

I made a Guix package for the linux-wifi-hotspot (CLI only) but now I am hesitant to submit it to Guix repo because it seems many people are having issues with actually using the core features like AP+WiFi at the same time, or are stuck at the "Creating a virtual WiFi interface..." step. Restarting the networking service does seem to work around this latter issue, but can hardly be integrated in a package, and in any case it seems the access point remains unstable and will get disabled in my case.

Edit /etc/NetworkManager/conf.d/ubuntu-system-adjustments.conf and change line: unmanaged-devices=none in: #unmanaged-devices=none

That did it for me, I changed ubuntu to debian as I don't use ubuntu distro, but otherwise worked perfectly.
