Re: Unable to connect to USB Tethering

Do I need to add it every now and then?
BTW, I worked for me before and after I've installed NetworkManager.

Re: Unable to connect to USB Tethering

You do need to add *some* meaningful information; notably what phone, what you've done, whether the phone appears on the usb… dmesg, journal, stuff.
Because we do not know anything about your system.
That's what the links I posted describe.

Also ensure to have read https://wiki.archlinux.org/index.php/Tethering


Sidenote: ifconfig is kinda deprecated, "man ip"

Re: Unable to connect to USB Tethering

I've reboot several times since October 29, 2020, which was the last time I connected my device to the system.
Do you want me to reboot again, now?

Re: Unable to connect to USB Tethering

You either update the kernel w/o the /boot partition mounted or boot from the root partition but updated to the /boot partition.

Edit: or you just updated the kernel and need to reboot - this has nothing to do w/ the tethering device.

Re: Unable to connect to USB Tethering

I don't known how to do it. I merely use

pacman -Syu

unless the news says anything concerning to manual updates.
P.S. When I startup the machine I get kernel errors, should I deal with it first?

Re: Unable to connect to USB Tethering

RedArcher,  What people are telling you is that the kernel that is being loaded by the boot loader is not the one that pacman has installed.  The kernel that is booting cannot find its modules.

Edit:  We were posting at the same time.   Yes.

What are the contents of /etc/fstab  ?
Are you booing in uEFI mode?
What bootloader are you using?

Re: Unable to connect to USB Tethering

Reboot, compare the output from #6 again.
If they're still different, post the outputs of "lsblk -f" and "mount"

Thank you for the clarification.

I think so, but I don't know.

GRUB, as I recall.

Re: Unable to connect to USB Tethering

I'd be interested in the output that Seth had requested, but I assert that the mount point for UUID=0772-8322 should be /boot, not /efi.  If you could please post that output...

/efi is fine for grub. It doesn't require that the kernel/initramfs are on the ESP.

Re: Unable to connect to USB Tethering

Good to know.   I use EFISTUB myself
