Known Issues
MacOS 10.15 "Catalina"
There is an unsolved issue with the root(/
) file system in 10.15
being read-only:
https://github.com/NixOS/nix/issues/2925
Our current recommended workaround is putting /nix
under /opt/nix
and symlinking it via /etc/synthetic.conf
:
sudo mkdir /opt/nix
sudo chown ${USER} /opt/nix
sudo sh -c "echo 'nix\t/opt/nix' >> /etc/synthetic.conf"
reboot
After the system reboots you should see the /nix
symlink in place:
% ls -l /nix
lrwxr-xr-x 1 root wheel 8 Oct 11 13:53 /nix -> /opt/nix
In order to be able to use Nix with a symlinked /nix
you need to include this in your shell:
export NIX_IGNORE_SYMLINK_STORE=1
Add it to your .bashrc
or any other shell config file.
NOTE: Your old /nix
directory will end up in /Users/Shared/Relocated Items/Security/nix
after OS upgrade.
Cache Downloads Timing Out
If copying from Nix Cache times out you can adjust the timeout by changing nix/nix.conf
:
stalled-download-timeout = 9001
NDK Bundle Download Failures
There is a known issue(#11111) where the fetching of Android NDK Bundle from our own cache host fails in various different ways:
unable to download 'https://nix-cache.status.im/nar/64g5wharwjj040rg1v8jnc5qhv1hkgds.nar':
HTTP error 200 (curl error: Stream error in the HTTP/2 framing layer)
unable to download 'https://nix-cache.status.im/nar/64g5wharwjj040rg1v8jnc5qhv1hkgds.nar':
HTTP error 200 (curl error: Transferred a partial file)
NAR for '/nix/store/psx79cnz1khfjlzkw3j8x9sb1jhk1v1a-ndk-bundle-21.0.6113669' fetched from 'https://nix-cache.status.im' is incomplete
Currently the simplest temporary solution is to edit nix/nix.conf
and comment out the extra-substituters
line.
This should allow Nix to download the NDK Bundle directly from Google servers rather than from our own cache.
extra-sandbox-paths
Is a Restricted Setting
When building Android on NixOS you might encounter the following error:
ignoring the user-specified setting 'extra-sandbox-paths', because it is a restricted setting and you are not a trusted user
You can mitigate this by setting the nix.trustedUsers
property.
NixOS Prioritizes System Config
Currently on NixOS NIX_CONF_DIR
is being ignored in favor of the default /etc/nix/nix.conf
.
This will be possible to fix once Nix 2.4
comes out with support for NIX_USER_CONF_FILES
.
