I'm dual booting Manjaro with Ubuntu, for some reason I went back to my Ubuntu and upgraded it a little just to see what's new.Ubuntu upgrade broke my grub config and replaced the Manjaro default (with os-prober).By broken I mean Kernel Panic on boot for Manjaro, Ubuntu is fine though.At this point I tried loading my configfile from the Manjaro boot partition, it worked but there was some driver error, same happened with all installed Kernels.In order to bring the system back to live and restoring Manjaro's grub while replacing Ubuntu's grub I tried chroot in to the Manjaro system fro Ubuntu using the official guide by Manjaro for manual chrooting.The chroot succeeded but I'm getting all sorts of messages from pacman when I'm trying to update packages.The messages are:error: GPGME error: Invalid crypto engineand for each package:File /var/cache/pacman/pkg/ncurses-6.0+20161112-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).Do you want to delete it? [Y/n]I'll probably try rebooting to Manjaro with the configfile again but I'm skeptical about the results.My Manjaro version is 16.10 while my Ubuntu version is 16.04.1.Thank you all.
