No worries. Have a great vacation!

    That said, if CI itself started to fail recently, there must be
    something broken
    in the sources, possibly in relation with a specific environement.
    Could you try
    to compile after a git checkout release/2.18.0-1? If that
    succeeds, you want to
    go through a git bisect to find the culprit.

That's a good idea--I'll try that next.

    PS: I guess going
    to help in debugging.

This page is all Greek to me at the moment, but I'll look into it. Thanks!

Quick explanation: among other things, this merge request introduces a --ci flag in,
which helps testing just as CI does, with the same compilersettings.

Compiling this branch with --ci yields fine resultsfor me. So, the issue is
very likely related to your environment. CI runs ina docker container that
is either Ubuntu 16 or 18. These ship with olderversions of FontForge than
my Ubuntu 20, as you'll notice in
(the version there being 20170731 while mine is 20190801).

Paging Jonas: could we perhaps add a Docker file for Ubuntu 20.04?

I hope your problem can be solved by installing a newer FontForge, which can be done from Ubuntu's newest apt repositories. To do that, I guess (guess!) you should add the
following line to /etc/apt/sources.list:

deb focal main universe

(view the full list of mirrors at


sudo apt update
sudo apt-get -t focal install fontforge

could do the trick, though I'm really unsure with apt usage.
