Hello,
Update: Grup update is too slow.

Grub update cannot completed after installation.
It’s waiting long time and my grub setup is gone.
I can restore grub, fix the problem with grup customizer.
But grup update is still slow when grub-customizer os-probing or updating grub.
My partition setup looks like this:

sda
sda1 /ubuntu distro or windows7
sda2 / antergos
sda3 /home
sda4 /swap

I install antergos to my 2 machine. 2-3 linux already installed. Both have same problems.
I was able to complete only after delete other linux partitions on the disk.

Am I missing something ? Any suggestions wellcome.

Thanks,

It’s looks extensions related.

Shutdown button and other buttons are missing after gnome 3.18
Buttons are come back after restart gnome.
