@svgeesus "PNGcheck, version 2.3.0 of 7 July 2007". Downloaded just now to Ubuntu running under Win11.
@bosak Wow that is truly ancient (and more recent versions fix several security issues)
@svgeesus That's what comes in with a fresh install. I could easily believe that the stuff coming from wherever the updates come from for the Windows 11 version of Ubuntu are not of the best quality.
