Pk11 [1] filed an orphan request for canon-tr8600-series [2]: I already reached out to the current maintainer via email around a month ago and have received no response. The current package crashes because the dependency needs to be changed from libxml2 to libxml2-legacy Interestingly they committed a comment to the PKGBUILD explaining a workaround, but did not actually implement a fix [1] https://aur.archlinux.org/account/Pk11/ [2] https://aur.archlinux.org/pkgbase/canon-tr8600-series/
