unable to restore r-universe package via renv

[zkamvar]

I am finding that I'm having trouble restoring an r-universe package from a lock file after it updates from the r-universe. According to a 2022 article by Jeroen Ooms, renv is supposed to fall back to using GitHub for this, but I'm finding that I cannot restore a lock file created with an r-universe package.

MWE

To reproduce this problem, I created a lock file using the released version of the repvar package from https://zkamvar.r-universe.dev (at the time, it was built from zkamvar/repvar@07e2051f169). I then added two commits and bumped the version number.

When the r-universe rebuilt from the source, I purged the package from my cache and attempted to initialize a new project from the lockfile

Lockfile

  ]

I think renv is getting confused here because there is no RemoteRef encoded in the lockfile, even though that shouldn't be required here. I can take a look.

Looks like it worked!

- None of the packages recorded in the lockfile are currently installed.
- Use `renv::restore()` to restore the project library.
