[Bug 1874880] Re: error running apt-add-repository

[Edson T. Marques]

Thanks for the information and the warning ... well, I try to be a tester trying to help a little bit. So I'm just reporting on a behavior hoping to be useful to developers. Without expectations...
After all, after so many years, I was never able to resist curiosity and news, so, from time to time (alias rarely in recent times) I have to reinstall ubuntu, but I like that :-D
Thank you again !
