While debugging this issue, I've noticed that sudoing in Ubuntu is supposed to preserve user $HOME by default [1]. Since how-can-i-help is also available in Ubuntu [2] and sudoing is preferred way of doing things in Ubuntu, this issue will most likely also affect Ubuntu users with default configurations. While I could try to implement a workaround inside hcih, I don't think it's a good idea - it would be error prone and would just fix a single, specific issue. However, adding a simple read/write check before performing a file operation is safe, simple and will be way more generic. Nothing special - if hcich cannot read/write to its files it will just print a warning (mentioning which files need to be chowned) and exit gracefully. I'll also add a short notice about running with sudo in man page. > I guess it's time to drop this old config :) > And now it works as expected. > > Thanks for the help and all the detailed explanations !
