ostree static-delta show -> error: openat: No such file or directory

[8a5n7d3y]

Hi there,

I generate an static-delta file, as follows:

ostree generate --filename=./ostree-delta.bin --inline --from=3fd5cdd819f0d13111a6e23f9314abbd2b035d621f79bc0f7d56f63e98f14e5b 01d7e89ed5c67d4a9082a3c56e9f1e5122b50a5a5480297f02763648b593bb1a

I can apply it fine on my device, but when I run ostree static-delta show, I get the following error:

ostree static-delta show ./ostree-delta.bin

Delta: ./ostree-delta.bin

On the one hand it is not a big deal, as I just need to get (To:hash) from the output, on the other hand there might be something else I am missing.

I am using quite an old version of ostree, as it is what comes by default in the yocto kirkstone provided by hardware manufacturer:

ostree --version
libostree:
Version: '2021.6'
Git: v2021.6
Features:

• libcurl
• ex-fsverity
• libarchive
• libmount
• systemd
• release
• p2p

Is it a known issue, has it been fixed (commit hash, so that I could back port it to the version I have), or it can just be ignored?

Thank you for your help

Cheers,
Andy
