Hi Doug,

I installed the newest version using homebrew on a mac, and now I get this at start:

```

Macaulay2, version 1.24.11

with packages: ConwayPolynomials, Elimination, IntegralClosure, InverseSystems, Isomorphism, LLLBases, MinimalPrimes, OnlineLookup,
               PackageCitations, Polyhedra, PrimaryDecomposition, ReesAlgebra, Saturation, TangentCone, Truncations, Varieties
/usr/local/share/Macaulay2/Core/packages.m2:260:65:(1):[22]: error: newPackage: expected Headline to be less than 100 characters
/usr/local/share/Macaulay2/Core/packages.m2:260:65:(1):[22]: --entering debugger (type help to see debugger commands)
/usr/local/share/Macaulay2/Core/packages.m2:260:60-260:128: --source code:
    if opts.Headline =!= null and #opts.Headline > 100 then error "newPackage: expected Headline to be less than 100 characters";

```

This seems to also affect my own package that I've written when I try to load it. 

Any idea how to fix this?

thanks,

Luke

Hi Luke,

There's now a limit on the length of the string passed to the Headline option to newPackage to 100 characters.

All of the packages that are distributed with Macaulay2 have headlines with lengths below this limit, so the issue must be with one of the packages that you have installed locally.  Try running the following:

scan(installedPackages(), readPackage)

This should tell you which package is the culprit.  Then you can edit the package source directly to shorten the Headline string. Or, if it's a package that's distributed with Macaulay2, you could run "uninstallPackage" on it so that the updated version with a shorter Headline gets loaded instead of your local copy.

Hello!

Thanks for creating Fedora packages of the new release. Unfortunately, on a system recently upgraded to Fedora 41, I get the following error when trying to install:

Could not depsolve transaction; 1 problem detected:
 Problem: conflicting requests
  - nothing provides Macaulay2-common = 1.24.11 needed by Macaulay2-1.24.11-1.x86_64 from @commandline

Any suggestions?

Thanks,

Fred

Hi Fred,

Did you download install both RPM's? There's also a "common" one that contains things like the .m2 files and documentation that don't depend on the specific version of Fedora.
