zstd -d: no such file or directory #809
Description
Hello, I have an issue regarding restoring caches on self hosted runners.
I am building the cache in a github runner, then in my self hosted runner, I am trying to restore it. I can see that the cache is actually being downloaded, but then when the tar command is running, it is failing to unpack it. Here's the log for it:
##[debug]Save intra-action state CACHE_KEY = ...e6f4

Basically, I can see the archive being downloaded in the folder but then i see the error in the output and the archive is gone.
When restoring cache from a Github runner, the tar command looks exactly the same but the cache is restored.
Cache Size: ~613 MB (643139890 B)
/usr/bin/tar --use-compress-program zstd -d -xf /home/runner/work/_temp/id/cache.tzst -P -C /home/runner/work/repo/repo
Cache restored successfully
In the self hosted runner, i do have tar and zstd installed as you can see from debug outputs as well. This of course results in a cache miss.
Any idea on what this particular issue is all about? Am I missing something and this Is just a configuration error?
