if I put an attrSet of packages in output.${system}.packages, I get error: A definition for option perSystem.x86_64-linux.packages.whatever' is not of type package'., but I I use legacyPackages instead that is fine.
Does someone knows a good reason for that ? output.${system} is itself an attrset of packages, you could just use that | 23:25:12 |
| aphasic | legacyPackages is there for nixpkgs to use but yeah it works ok for any attrs | 23:26:11 |

 René | Hello. I tried copying a closure from my machine to my binary cache using nix copy --no-check-sigs and I get the error cannot add path /nix/store/... because it lacks a signature by a trusted key. I signed the package and added the pubkey on the cache nix.conf

| René | Hi. I'm having an issue installing a flake with nix profile install. The test suite of the package runs some checks with the MySQL database and it is failing with "can't connect with mysqld.sock". What's odd is that running the test suite with nix develop -c bash "cabal test" succeeds.

 Sarah Clark | Which platform and what's your sandbox setting? | 20:40:05 |

| René | I'm running Nix on Ubuntu | 20:45:15 |
| René | installing the flake with --impure gives the same issue
| 20:45:43 |
| Sarah Clark | Nix packages expect the socket at /run/mysqld/mysqld.sock but Ubuntu defaults to /var/run/mysqld/mysqld.sock. If you know where your sock file is, you can use export MYSQL_UNIX_PORT with the socket path | 20:56:50 |

| Sarah Clark | I"m sorry that didn't work. Which package are you installing? (I want to check that it's not a problem with the derivation.) | 17:11:58 |

| René | It's not a public package, I'm trying to set up the CI to my server. The flake builds, runs and tests correctly when you git clone the repo into the server. But if you try to nix profile install, I get this "MySQL not found" error. I even changed the code to not use the socket and instead use TCP and I got ConnectionError {errFunction = "connect", errNumber = 2002, errMessage = "Can't connect to server on '127.0.0.1' (115)"}.
| 12:20:56 |
| René | is there an option for nix profile install to skip the checkPhase?
