When you pressed "Install" button, you got a message: --8<---------------cut here---------------start------------->8--- Profile: /var/guix/profiles/system-XX-link/profile Package(s) to install: ncurses-6.0:doc (gnu/packages/ncurses.scm:90:4) --8<---------------cut here---------------end--------------->8--- And you confirmed, that you wanted to install it in /var/guix/profiles/system-XX-link/profile :-) > That is supported, isn't it? It is. For example, you can "M-x guix-packages-by-name RET ncurses" (package names are completed) and install it the way you tried. Or from a list of packages (for example, after "M-x guix-search-by-name RET guile"), you can mark several packages for installing with "i" and execute the operation with "x". Operations on packages (installing/upgrading/deleting) in these "List"/"Info" buffers are performed using a profile which is the current for these buffers. Moreover the buffers are named like this: *Guix Package Info: guix-profile* "guix-profile" here is the last part of the profile file name: "/var/guix/profiles/per-user//guix-profile". (We can change a default buffer name to contain a full profile name, but it will be too long, I think) Anyway, when you looked at the "global" packages, a system profile was used (as this is where global packages are installed), and when you tried to install "doc" output of ncurses, it was tried to be installed in the system profile which is impossible.

The only way to install packages globally is by adding them to a system config and running "guix system reconfigure". If you mean to install packages into a root's profile (which is probably /root/.guix-profile), then yes: in the same way as you would do for a non-root user. > I only tried it on root because I thought not work for uer was a gut.

Thanks :-) OK, you are free to do it the way you like. I was just saying that managing users profile is more convenient IMO. > Also, just to be clear, I was not trying to install the curses.6 doc > globally. I was trying to install it locally as 1) user, and when that > failed as 2) root. Now I understand your intention, but in fact you tried to install it to a system profile both times. After all I see why you were confused. Emacs interface has always been aimed only for a user profile. "M-x guix-system-generations" was added very recently just to show what systems you have and what global packages they contain, and by accident you can perform the same actions on these system packages as with user profile. I'm going to remove this false possibility (I mean, a user shouldn't get a chance to install anything to a system profile) to avoid future confusions. Thanks for reporting!
