Upgrading NixOS to Unstable Channel

As an Arch Linux user, I am used to using the lastest packages. Thus, I upgrade my NixOS to unstable channel. 1 2 3 4 5 # switch channel sudo nix-channel --add https://nixos.org/channels/nixos-unstable nixos sudo nixos-rebuild switch --upgrade # show version nixos-version References: Upgrading NixOS - NixOS manual https://channels.nixos.org/

Fixing File Permission Problem of Jellyfin on Arch Linux

This tutorial should work for other Linux distributions, but I only tested it on Arch Linux. In order to add a directory to a Jellyfin library, Jellyfin needs to access the directory and all its parent directories. If you add ~/Videos to a library, Jellyfin fails to access it. Jellyfin runs as user jellyfin. Jellyfin can access ~/Videos (other::r-x) but can’t access its parent ~ (other::---). 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 ❯ getfacl ~/Videos getfacl: Removing leading '/' from absolute path names # file: home/cyrusyip/Videos # owner: cyrusyip # group: cyrusyip user::rwx group::r-x mask::r-x other::r-x ❯ getfacl ~ getfacl: Removing leading '/' from absolute path names # file: home/cyrusyip # owner: cyrusyip # group: cyrusyip user::rwx group::--- mask::--- other::--- To fix it, grant Jellyfin execution permission for the home directory.

Removing Python 2 on Arch Linux

Python 2 was dropped from Arch Linux. It was lucky that there were only two python2 packages on my Arch. 1 2 3 4 5 ❯ pacman -Qs python2 local/python2 2.7.18-5 A high-level scripting language local/python2-setuptools 2:44.1.1-2 Easily download, build, install, upgrade, and uninstall Python packages I removed them without hesitation. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 ❯ sudo pacman -Rscn python2 python2-setuptools checking dependencies...
