Same error when I do rerun second time.

[axet]

Looks like caused by zero length of './GAMMA/downloads/HighResLoadingScreenV1.1.7z'

[Mord3rca]

$ 7z l ~/Downloads/GAMMA_addons_downloads.7z | grep  HighRes
2021-11-11 00:46:09 ....A    109661648               downloads/HighResLoadingScreenV1.1.7z

Addons in the 7z archive, you probably had something failing while decompressing it.

[axet]

As I mention above it has zero size.

[Mord3rca]

Using check-md5 with option --redownload will fix this cache issue

gamma-launcher check-md5 --gamma <path/to/gamma> --redownload

[axet]

Simply removing the file does the trick.

I guess here are two issues: 1) zero file created and not removed after error 2) crashing trying to open zero file size instead of showing error / retry

[Mord3rca]

Closing this issue since launcher is not responsible of download cache if archives are created/modified by an external resource.

Also, gamma-launcher check-md5 --update-cache --gamma <GAMMA dir> should update the cache

[axet]

It never been modified by external app. It was first clean run.
