#[Linux] Can't activate a license when using distributions which have deprecated SHA-1

Reproduction steps: 1. Install Unity Hub package following the steps from [https://docs.unity3d.com/hub/manual/InstallHub.html|https://docs.unity3d.com/hub/manual/InstallHub.html] 2. In Unity Hub, sign in to your account 3. Assign a free license or activate paid one Expected results: A license is added to the Unity Hub and is visible in the list Actual results: License is not added to the Unity Hub and is not visible in the list Reproduced with: 3.9.1, 3.10.0-beta.1 Reproduced on: RHEL 9, Fedora 41 Not reproduced on: Windows 10, Ubuntu 22.04, Ubuntu 24.04, Ubuntu 24.10 Note: This is due to the Licensing client still relying on SHA-1 hashing, while it is deprecated, and will eventually be removed from all major distributions

Just ran into this as well after updating to Fedora 41. The workaround suggested by Flagrama and BPS_86 solved the issue. Thanks a lot! You are lifesavers. But the underlying issue is still needs to be fixed. As this took quite a bit of googling to find.

+1 waiting for the issue to be resolved Unity Hub 3.10.0 (e032492) Switching crypto-policies doesn't work for me at all. So I can't use my Linux machine at all for Unity dev

edit typo: `update-crypto-policies --set DEFAULT:SHA1` and `update-crypto-policies --set DEFAULT` is the correct one

@FLAGRAMA don't use that if you only need it for unityhub, use `update-crypto-policies --set default:SHA1` instead. If you don't mind the hassle, you can use `update-crypto-policies --set default:SHA1`, open unityhub, once opened type `update-crypto-policies --set default` again to return it to normal. This is for safety reason.

I installed Unity inside a Distrobox, How can I enable this: `sudo: update-crypto-policies: command not found` ?

On Fedora specifically you can workaround this using the old crypto policy profile for Fedora 41 using `update-crypto-policies --set FEDORA40` and rebooting. This should use the old crypto policy that verifies SHA-1 hashes. It'll stick around for several more Fedora releases so there's probably a year or so before SHA-1 verification becomes completely impossible, and it'll probably get reset on any version upgrade, so having this issues fixed sooner rather than later is a must.

Complete showstopper as I am not able to work on any projects anymore. Any known workarounds till this is fixed?
