[Bug]: ZIM files not deleting properly

[PattheRat22]

Issue Category

Content Management (ZIM, Maps, Collections)

Bug Description

I was downloading Wikipedia, and somehow the file got corrupted while it was downloading. When I went to the Content Manager and attempted to delete the file, it did not delete the file. Instead, it gave me an error message in the web console and it kept giving me errors in the 'nomad_admin' log.

Steps to Reproduce

1. Click on 'Content Manager'
2. Delete any file

Expected Behavior

The corrupt file would be deleted, and it would disappear from the list of .zim files.

Actual Behavior

The file was not deleted, and it spat out an error in the web console, and it kept spitting out errors in nomad_admin around every 10 seconds.

No response

Additional Context

I had to stop NOMAD, manually delete the file, and then restart it. That seemed to stop the errors from appearing over and over, but I still can't delete files I want to delete using the Content Manager. I still have to manually delete files.

This is actually a problem with either ZIMs in general but it happened to me in Kiwix standalone as well. If the download is stopped on a zim file it's basically bricked and Kiwix won't delete or resume downloading them.
In my case with Kiwix what fixed it for me was manually finding the zim and hard deleting it then restarting the download. Wary of this issue I decided to only install 1 part at a time with NOMAD so that if a download gets bricked It'll be easier to see which Zim went wrong.
I'm no expert here but I recommend opening the path to where the content is saved to, deleting it and then restarting, maybe even rebooting first.

Thanks for reporting. This sounds like the ZIM delete endpoint is hitting an error when the file is corrupted or partially downloaded. The community note about this being a Kiwix-wide issue with interrupted downloads is helpful context, but the NOMAD UI should still be able to delete the file from disk even if it's corrupt. Keeping this open.

[LuisMIguelFurlanettoSousa]

I'd like to take this one. The browser console error deleteZimFile is not a function suggests there's a missing or misnamed method in the API client. I'll investigate the frontend delete flow and the backend endpoint, then submit a fix.

[PattheRat22]

I see that this issue now has a solution and the bug may be fixed in the future. Thanks for the help!
