I was thinking to burn a new iso to use for the grub reinstall (or to reinstall the system with in case I flub the grub operation). I use the i3 edition. Is it up to date with the 5.8 kernel, etc?
@oberon is the maintainer. You can easily change the kernel in manjaro settings manager regardless of what gets installed first. I3 image should work fine.
you can use chroot with USB iso
Latest version is 20.0.3 with kernel linux56, like the official editions, too
Thanks, everyone. The update and grub reinstall were entirely painless, but at least now I have a freshly-minted, up-to-date usb should the need for it arise.
