Hi, I fully agree with your analysis the reasons were: - I installed ddrescue in distrobox and wanted to use it from outside distrobox by exporting its bin - then by mistake I thought that sudo doesn't exist either outside distrobox as used to be in Vanilla distribution, and I exported it as well ;-) I was however astonished that it had such heavy impact because now sudoing wasn't possible at all. Took me a while to find that the work around was easy :-( Anyhow thank you and please note : I am a big fan of your distro! Regards, Marco
