Cannot login (login screen loop) after some packages are installed

Cannot login (login screen loop) after some packages are installed

Hi Nikos,

my apologies for the long delay.  You may have better luck on
help-guix@gnu.org; bug-guix@gnu.org is usually for bugs which can be
reproduced by others.

I don’t know what the problem is, but I suspect that trisquel is unhappy
with environment variables that Guix has set.  Guix defines variables
based on the contents of your profile at ~/.guix-profile/etc/profile.
In your shell initialization you probably load them; e.g. with this
snippet in ~/.bash_profile:

    GUIX_PROFILE=$HOME/.guix-profile
    source $GUIX_PROFILE/etc/profile

When you comment this Guix will not set any variables, so it has no way
of affecting your environment at all.  Can you log in after removing
these lines?  (You can evaluate these lines after logging in.)

If so, we should try to figure out which of these variables is
responsible.  Could you please show the contents of that etc/profile
file?  A common suspect is one of the XDG_* variables.

Hope that helps!

Try adding the following line to your ~/.profile
export
XDG_DATA_DIRS="/usr/local/share:/usr/share/${XDG_DATA_DIRS:+:}$XDG_DATA
_DIRS"

This solution, brought by Adfeno, worked for me. This is the only
problem I had with Guix on Trisquel so far.

David.
