Hi All, On the forum someone flagged they were having a failure when doing a build with the download stage for zstd. I checked and confirmed the problem if i removed the zstd source file I had downloaded when doing the last update of zstd. The file in the source tree has a different md5 sum as the one I used for the lfs file in my update build. The download site https://github.com/facebook/zstd/releases/tag/v1.5.0 has both a zstd-1.5.0.tar.gz and "Souce code (tar.gz)" entry. Checking the md5 sums the one used in my build patch submission was the direct zstd-1.5.0.tar.gz file and the one in the IPFire source tree is the "Source code (tar.gz)" file. The source tree needs to be changed to use the direct file location. Regards, Adolf.
