Followup-For: Bug #953144 origami is missing a dependency on lsb-release (needed for os identification).
The URL https://zelut.org/projects/misc/finstall is no longer available and causes the reported error. There is no validation (e.g. hash/signature checking) on the downloaded bits, which contain code to be executed ... BTW, as a downloader package, why isn't this in contrib? Andreas
