pict-rs made changes to the database schema between 0.3 and 0.4. It
|
|
will apply these automatically on the first run of 0.4, but the old
|
|
version will no longer work after that.
|
|
|
|
Your configuration is currently using the old default of pict-rs
|
|
0.3. Unfortunately, 0.3 no longer builds due to the Rust 1.80 update,
|
|
and has been removed. pict-rs has already been updated to 0.5 in
|
|
Nixpkgs, which has another schema change but removes the migration
|
|
logic for 0.3.
|
|
|
|
You will need to migrate to 0.4 first, and then to 0.5. As 0.4 is
|
|
no longer present in Nixpkgs, the recommended migration path is:
|
|
|
|
* Import a separate Nixpkgs old enough to contain 0.4, temporarily
|
|
set `services.pict-rs.package` to its pict-rs, set the
|
|
`PICTRS__OLD_DB__PATH` environment variable for the migration, and
|
|
activate your configuration to start it. The following configuration
|
|
snippet should work:
|
|
|
|
services.pict-rs.package =
|
|
(import (builtins.fetchTarball {
|
|
url = "https://github.com/NixOS/nixpkgs/archive/9b19f5e77dd906cb52dade0b7bd280339d2a1f3d.tar.gz";
|
|
sha256 = "sha256:0939vbhln9d33xkqw63nsk908k03fxihj85zaf70i3il9z42q8mc";
|
|
}) pkgs.config).pict-rs;
|
|
|
|
systemd.services.pict-rs.environment.PICTRS__OLD_DB__PATH = config.services.pict-rs.dataDir;
|
|
|
|
* After the migration to 0.4 completes, remove the package and
|
|
environment variable overrides, set `services.pict-rs.package` to
|
|
the current `pkgs.pict-rs` instead, and activate your configuration
|
|
to begin the migration to 0.5.
|
|
|
|

The NixOS module will handle the configuration changes for you,
|
|
at least.
