I am preparing Build Metadata to submit a new app, and everything runs fine except for
checkupdates, which gives the following (see <https://gitlab.com/yawnoc/f-droid-data/-/jobs/2017644228>):
[...] 2022-01-26 10:34:52,707 WARNING: apksigner not found! Cannot sign or verify modern APKs [...] ERROR: Job failed: exit code 1
There appear to be no other issues, and the diff at the bottom just has an insertion of
AutoName (which is meant to be automatic I think).
apksigner causing the problem, and if so, how do I get it to run on the server?
