Hi all,

is the package manager server down or do I have a problem with my installation (swipl 8.1.5 on Ubuntu)? If I try to install a package with pack\_install or try to resolve the url manually, I get a server error 500.

Thanks  
Daniel

Seems to work for me.

I installed [Package “func”](https://www.swi-prolog.org/pack/list?p=func) which I know has not been previously installed.

I think that is the problem. At some point the SWI-Prolog website moved to HTTPS and older versions cannot handle that. Ether use the stable or a more recent development version.

… that was the problem. I updated to the latest dev-release and everything works now fine.

Thanks,
