Hi, This morning's `pacman -Su' had a problem building the fallback initcpio image for 4.14.79-1-lts. Yesterday's /var/log/pacman.log shows [2018-11-06 10:45] [ALPM] upgraded linux-lts (4.14.78-1 -> 4.14.79-1) [2018-11-06 10:45] [ALPM] running '60-linux-lts.hook'... [2018-11-06 10:45] [ALPM] running '90-linux-lts.hook'... that all went well. Today, package `linux-lts' wasn't upgraded but 90-linux-lts.hook was triggered. 60-linux-lts.hook wasn't. pacman's TTY output complained `error: command failed to execute correctly' and the list of `Running' build hooks didn't complete. The same steps for package `linux' immediately after didn't have the same problem. :: Running post-transaction hooks...

I was hoping pacman.log might have more detail, but it doesn't even record that there was an error. I think that's a bug.

And after that, is attempting another build of the image as simple as `/usr/bin/mkinitcpio -p linux-lts' as root? -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
