Hello maintainers, I'm reporting this here as this looks like a package configuration issue, combined with possible problems in HP support for Debian stable[1] and finally the Ubuntu site wants me to create an account, acknowledge long legal text which I would like to avoid for this small issue. A few days ago I installed an HP scanner and the necessary software (including hplip-gui) to use it. It works (after needing to allow a firmware download), but since then I get the following syslog entry: hp-systray: hp-systray[3176]: error: option -s not recognized If this warning is harmless, then please supply a logcheck rule which filters it out. Please note that I'm using a completely different printer, so the messages below reggarding the printer are expected and CUPS works for it. Thanks! [1] See the messages below, e.g. debian-11 version is not supported.
