[cassava]

Thanks for the issue. I'll see if I can reproduce it.

[cassava]

Hi @daurnimator, I can't currently reproduce this. Are you getting this regularly? Could you try with the latest repoctl version?

[grensjo]

I regularly experience this issue with the latest release (v0.16). It seems to be non-deterministic, but it happens often enough that I can reproduce by running a command such as repoctl list or repoctl status 5 times quickly in a row.

However, the issue seems to be gone when using repoctl-git. Perhaps it is time to make a new release?

[cassava]

Thanks for the update. You are probably right, I'll see what I can do. :-D

[cassava]

Hey @grensjo, I just uploaded the 0.17 release here on Github and on AUR. Let me know if you run into any problems. Thanks!

[grensjo]

Thanks, will do! It seems like you forgot to update the .SRCINFO file though (it is still listed as 0.16 in AUR).

[cassava]

Thanks, forget that every time!

[cassava]

Please re-open if the problem occurs again. Closing for now.
