Stephen -- I got a reply on the Repositories and Backports forum: https://ubuntuforums.org/showthread.php?t=2427539
SO this person said we should be using the Backports repository. That changes all the rules! I added a follow-up question. In case you don't know, Backports is a special standard repository for each version of Ubuntu containing newer packages for that release. It's fairly easy to get packages into Backports. (See below.**) It turns out nowadays (for quite a few years now; I missed the memo) backports is activated by default in Ubuntu. But apparently NOT in the sbuild chroot! I probably won't be able to try again this weekend. It should be fairly straightforward to activate the backports repository in sbuild, but if you or I start tinkering with a PPA I don't know what to do. I suppose they have it activated there. Here's what I would suggest. Create a new file for sources.list in the chroot having two lines $ sbuild-shell bionic-amd64 $ su password: # cd /etc/apt/sources.list.d/ # cat > /etc/apt/sources.list.d/bionic-backports.list [paste the following two lines into the file, and then type ctrl-Z] deb http://archive.ubuntu.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ bionic-backports main restricted universe multiverse Then you can update apt in the chroot to see that the backports repository is available. **The backport process: Someone wants a newer package, and builds it (on sbuild or pbuilder or a PPA) to confirm it builds in x version of Ubuntu, then that person requests that it go into the Backports repository for Ubuntu x. A backport volunteer confirms that it builds, and copies into the repository for Ubuntu x. The new version then becomes available to everyone who has the Backports repository activated (everyone). If, for example, the latest GnuCash package builds without errors with backported packages for Bionic, then theoretically it can easily go into the Backports repository for Bionic. No PPA needed! (Not that I expect this to happen for Bionic, but it might work for Disco, for example.) _______________________________________________ gnucash-devel mailing list gnucash-devel@gnucash.org https://lists.gnucash.org/mailman/listinfo/gnucash-devel
