I gave the Launchpad a cursory check but wasn't able to find what I was looking for. In addition, I scrolled back through the Git history a ways and found a commit that seems to have working Calibre at the same version. $ guix time-machine --commit=9d25ee30b188f9202cc14f7cd25ba8a1c3ec1a72 -- package --show=calibre name: calibre version: 5.21.0 ,,, $ guix time-machine --commit=9d25ee30b188f9202cc14f7cd25ba8a1c3ec1a72 -- shell calibre -- ebook-viewer brings up a working version of the reader. Thank you for the information about the time-machine command. I started to do a Git bisect on my copy of the repository, but found that it was intractable to build the versions of Guix necessary. Part of that seems to be related to some merges: Some of the candidate commits had dates from 2020 on them and the candidate set was rather large. Is there a smarter way to hunt down the commit where Calibre broke?
