Hello those who need help, It is unfortunate that Arch Rollback Machine (A.R.M.) has shut down. I just want to tell those who need to build old packages: There is a svn/git repo for ABS. You can fetch it for old PKGBUILDs. Now I use those PKGBUILDs to keep a productive server stable. I share my idea here and hope that it can solve your problem.

If anyone find it useful, please consider appending this to the Downgrading_Packages page on ArchWiki. -- Best regards, StarBrilliant (@m13253)
