Why FreeCAD probably cannot be downloaded on slow connections from GitHub

[mildred593]

I am trying for two days to download the latest FreeCAD (0.19) and failing because the connection stops in between. using wget -c to resume the download results in corrupt binaries.

I think I know why FreeCAD is not downloading properly. GitHub is using AWS S3 under the hood with pre-signed URLs valid only for some amount of time. After that, I believe S3 is closing the connection. Probably the redirect between GitHub and S3 is the reason why resuming a download fails too. That means on a fast connection you can download, and not on a slow connection. I verified this by using a server I have online with a fast Internet connection, and indeed, the download is successful and checksum is OK.

I believe the solution could be to host the files outside of AWS S3 until GitHub solves the problem.

edit : I sent a support request to GitHub

Maybe the problem is that FreeCAD is compiled daily so download link becomes obsolete every 24 hours ???

No, I think this is another issue all together. I even mentioned it on the AppImage page (in the banner at the top). It may also have to do with web connections (such as a poor wifi connection) that are not stable.

You can try to clone from a mirror like the one I have set up : https://framagit.org/freecad/FreeCAD
Then you change eventually change remote to get diff from github.

Edit : Oops, never mind, you are talking about binaries, not source code.
