I’m trying to install Guix as a package manager on Fedora Workstation 42. I think I’m running into some SELinux issues.
I installed Guix (1.4) with the script: https://guix.gnu.org/install.sh
I’m seeing this error.
$ guix pull
guix pull: error: remounting /gnu/store writable: Permission denied
I noticed if I run sudo setenforce 0, then try guix pull, everything works… but obviously that’s a pretty heavy-handed solution… I’d like to not disable SELinux.
OK, the commands from here helped.
$ sudo semodule -i /var/guix/profiles/per-user/root/current-guix/share/selinux/guix-daemon.cil
$ sudo mount -o remount,rw /gnu/store
$ sudo restorecon -R /gnu /var/guix
$ sudo systemctl restart guix-daemon
However, whenever I open a shell I’m getting this. Seems like there’s a broken symlink…
bash: /home/me/.guix-profile/etc/profile: No such file or directory
$ ls -l /home/me/.guix-profile
lrwxrwxrwx. 1 me me 46 Aug 1 16:34 /home/me/.guix-profile -> /var/guix/profiles/per-user/me/guix-profile
$ ls -l /var/guix/profiles/per-user/me/guix-profile
ls: cannot access '/var/guix/profiles/per-user/me/guix-profile': No such file or directory
I did a bunch of stuff in between. I don’t remember what exactly, so maybe I just need to do clean install… if only I could --roll-back…
Update
I deleted all the symlinks I had in my home directory, then ran guix home reconfigure home.scm, rebooted my machine for good luck, and now everything works! No errors! 
Another update: The guix-daemon hit permission denied again… not entirely sure why… I suspect it might be because I did a sudo guix pull last night and maybe that did something…
Anyway, I re-ran:
$ sudo semodule -i /var/guix/profiles/per-user/root/current-guix/share/selinux/guix-daemon.cil
$ sudo mount -o remount,rw /gnu/store
$ sudo restorecon -R /gnu /var/guix
$ sudo systemctl restart guix-daemon
And everything seems to be working again… I rebooted my computer and didn’t hit the permission denied errors after running those commands… so I guess I’m good.
