[question] Conan upload failed with "[Errno 2] No such file or directory"

[Mopcho]

What is your question?

During the run of

conan upload --list=promote.json -r=products -c -cc core.upload:parallel=1

we encountered the following error:

-------- Uploading artifacts --------
Upload completed in 0s
ERROR: Traceback (most recent call last):

Could you please give us some insight ?

Hi @Mopcho

Thanks for the feedback.
I think that you are hitting the same error that was reported in #18877

This error has already been fixed in #18878 and it will be released soon in next Conan 2.21.
If you want to try it today, you might try to run Conan from source, the develop2 default branch already contains this fix. Otherwise Conan 2.21 will happen end of month.

Note: to confirm if it is the same issue:

• The key is the --list=promote.json promote.json file was created and contains information from a previous upload flow
• It will contain fields such as files from a previous upload, that no longer exist

This also gives you a workaround without waiting till the next release, you can use jq to remove those fields before the conan upload command, and it should work then.

Hi @memsharded,
I can confirm now, we used a prerelease version of conan and the issue disappeared. Thanks for the insight and quick response !

[memsharded]

Great, closing then the issue as solved, to be released in 2.21.
Thanks for the feedback!
