 zitrone 🍋 | Anyone got an idea what error: cannot change ownership of '/nix/var/nix/b/5i50qd60sib1gcpvdmbrr667pd': Invalid argument means, and what i could do about it?
It happens on one of my machines any time when i try to build a package that actually needs building (not cached).
/nix/var/nix/b is drwxr-xr-x root root like on my laptop, where the error is not happening. | 01:18:21 |
| zitrone 🍋 | i found the problem: containers
the other computer it fails on is a lxc container
the container only has 16 bit UID and GIDs
because of that it fails to chown :872415232 /nix/var/nix/b/5i50qd60sib1gcpvdmbrr667pd: "Invalid argument" | 04:23:39 |

 aloisw | Are you connecting from outside the container? Also what exactly are you doing, that ID looks suspiciously like one assigned by auto-allocate-uids but that should be about the builder uids, whereas the whown should happen to the requester uid. | 05:16:19 |

| Aijokey | I have problem | 07:31:38 |
| Aijokey | ❯ ulimit
unlimited | 07:32:01 |
 K900 | This is on the daemon, presumably | 07:33:03 |
| Aijokey | Is there any way to fix, i cant switch | 07:47:21 |
| K900 | Are you running some sort of "hardened" setup? | 07:47:34 |
| Aijokey | no | 07:55:23 |

 raitobezarius | you can build without the daemon the system | 09:23:41 |

you can build without the daemon the system How? | 09:24:02 |
| raitobezarius | NIX_REMOTE=local <your command that rebuilds your system> if that respects environment variables | 09:24:18 |
| raitobezarius | but i'm more concerned that you are reaching open files limit with the daemon | 09:24:30 |
| raitobezarius | what does systemctl cat nix-daemon show? | 09:24:38 |
| Aijokey | In reply to @raitobezarius:matrix.org
what does systemctl cat nix-daemon show? For now I can't access pc, no electricity | 09:25:13 |
| raitobezarius | No problem, let us know when you can access it again | 09:25:31 |
| Aijokey | OK | 09:25:40 |
