test.yaml workflow fails because of cache corruption after upgrading to anchor 0.31.0

[borisnieuwenhuis]

After upgrading our setup to the new Anchor version 0.31.0 and also an Solana version upgrade to 2.1.0

From Anchor.toml

`
anchor_version = "0.31.0"

solana_version = "2.1.0"
`

the tests pipelines based on https://github.com/solana-developers/github-workflows/blob/main/.github/workflows/test.yaml started to randomly fail in step

Run solana-developers/github-actions/[email protected]

The error shown is

Run echo "Running tests for program: coordinator" Running tests for program: coordinator Error: Failed to list installedsolana` versions

Stack backtrace:
0: anyhow::error::::msg
1: anchor_cli::override_toolchain::override_solana_version
2: anchor::main
3: std::sys::backtrace::__rust_begin_short_backtrace

7: _start

Run echo "Tests failed! Check the logs above for details."

`

Deleting the github action caches fixes it for some finite time after which it starts failing again.

Hey, thank you very much for the issue. I have not updated yet to anchor 0.31.0 yet. I hope i will have time to do that early next week. If you find a fix would be great if you could pr it. 🥰 The cache should cache depending on the anchor version so there should not be a conflict with earlier versions idealy 🤔

@Woody4618 It looks like the problem went away after upgrading to solana_version 2.1.16. I will keep you updated if I see it failing again.

@Woody4618 I was too fast, it now breaks again in the same way

[Woody4618]

Can you please share your repository so i can debug it?

[borisnieuwenhuis]

@Woody4618 I managed to reproduce it with the hello_solana program from https://github.com/solana-developers/program-examples
