Reboot hangs on wpa_supplicant, NetworkManager

[orc]

Hi, I recently installed Linux mint cinnamon on my Alienware 17 r2, everting works fine, except that reboot and shut dawn always hangs in the the process below.

waiting for process: wpa_supplicant, NetworkManager

It stays on that line for a looong time any eventually shuts down.

I already changed.

Code: Select all

GRUB_CMDLINE_LINUX=""

to

Code: Select all

GRUB_CMDLINE_LINUX="reboot=efi"

and it didn't solve it.
Any help would be much appreciated.

Try

Code: Select all

sudo systemctl disable NetworkManager-wait-online.service

and reboot. If it doesn't make a difference, you can re-enable it with the same command (replace disable with enable),

Hi spamegg, thanks for your reply.

I already tried it, I shoot down and also reboot and it didn't make a difference, it is still hanging on the same process.

any thoughts?

[deepakdeshp]

As spamegg says use latest version of kernel series 5.4. Reboot to it and test.

Code: Select all

 uname -r

gives the running kernel.

[orc]

Hi.
I just switch to the latest kernel from the 5.4 series, please see below.

Code: Select all

5.4.0-72-generic

Unfortunately is still doing the same thing, Any other ideas to fix this please?

[orc]

Hi, any suggestions would much appreciated...

[orc]

SOLVED(kind of).

Hi, well... I didn't have any luck solving this on mint, I also tried ubuntu and pop and I had the exact same problem. A couple days ago installed manjaro and I ididn't have that issue, so it seems is something related with Debian based distros. At the end I'm going to try to use manjaro as my daily driver, I really like mint but not been able to shutdown or reboot is a deal breaker for me.

Thank you to the people that replied this post.

Cheers.

Code: Select all

 sudo init 0

shuts it down. I guess it won't work but worth trying.

Hi deepakdeshp.

It did shutdown without hanging ,is there a way to do something similar to reboot?

Thanks.

[deepakdeshp]

Code: Select all

 sudo init 6

for reboot.

Unfortunately didn't work to reboot, it also hanged on the same processes. Any other ideas?

Thank you.
