I use linux as my main os and everything is great exept i have to boot into windows to download a modpack and then copy it to a multimc instance. It would be great if there was a multimc instance or just a download with all of the mods and configs.

Thanks in advance

instead of multimc, you could use Prism Launcher, which is a fork of multimc with curseforge pack support, and should.be backwards compat with multimc instances

The pack is distributed in the standardized format supported by all of these launchers. That MultiMC in particular is unable to download from CurseForge anymore is not a fault of our pack and there is no compelling reason to create a different type of release (and it may not be allowed depending on redistribution limitations of some mods).

As noted in the chart in our Playing on Dev guide, MultiMC no longer supports downloading packs directly from CurseForge or FTB's sites (they were told to stop doing so and complied). They support importing instances created by the FTB app as a workaround, but that's not much help on Linux.

Following CurseForge's API changes that give empty download links for projects that haven't opted-in to third party downloads, third-party launchers have implemented one of a variety of workarounds to download packs from CurseForge.

Most of these launchers also have a Linux version. If you want to have a similar experience to before, PolyMC is a fork of MultiMC, and Prism (mentioned in the prior post) is a fork of PolyMC. GDLauncher is electron-based with a Linux client, and I believe they recently entered a partnership similar to what FTB did so they might qualify as a second-party launcher now. ATLauncher has been around a long time and they have a Linux client as well.
