troubleshooting

main

• first try:

nix build nixpkgs#<pkg name>
eza --tree result/ --level 3

cache/store related

• first try running with args:

nixwird --refresh --repair

• if nix store is broken:

sudo nix-collect-garbage -d
nix-store --verify --check-contents --repair

• if any derivations cannot be fixed with above command, try:

sudo nix-store --delete --ignore-liveness /nix/store/<derivation location>.drv
