2023/06/01 13:46:13 Error when generating mo files: couldn't compile mo file from "../../po/de.po": exit status 1.
Command output: msgfmt: error while opening "/<<PKGBUILDDIR>>/debian/zsys/usr/share/locale/de/LC_MESSAGES/zsys.mo" for writing: Not a directory

Is shocking given it just does this:

 if err := generators.CleanDirectory(baseLocaleDir); err != nil {
  log.Fatalln(err)
 }

....
  if err := os.MkdirAll(outDir, 0755); err != nil {
   return fmt.Errorf("couldn't create %q: %v", out, err)
  }
  if out, err := exec.Command("msgfmt",
   "--output-file="+filepath.Join(outDir, config.TEXTDOMAIN+".mo"),
   candidate).CombinedOutput(); err != nil {
   return fmt.Errorf("couldn't compile mo file from %q: %v.\nCommand output: %s", candidate, err, out)
  }

meaning it deleted dirs, created dirs, and yet couldn't write to said dir.

almost as if mkdirall stopped being atomic?

retries make it work.
