Hi all, One of my users has asked me to build an older version of freefem (3.61) to try out an older script. I’ve quickly discovered that the download/getall script for that version points to sites that no longer exist. I’ve found most of the 3rd party packages hosted at [http://pkgs.freefem.org](http://pkgs.freefem.org) but I’m still missing slepc-3.9.1.tar.gz as the primary site for it ( [http://slepc.upv.es](http://slepc.upv.es)) has been down for a few days. Can anyone advise where I can find a copy of this package? A web search hasn’t revealed any promising candidates. Regards, Mike ---

Here you go: [https://gitlab.com/slepc/slepc/-/archive/v3.9.1/slepc-v3.9.1.tar.gz](https://gitlab.com/slepc/slepc/-/archive/v3.9.1/slepc-v3.9.1.tar.gz). You’ll probably have to adjust the MD5 hash from `download/getall`. ---

Many thanks - I’ve downloaded that and changed the md5sum entry in the getall script
