Why is the download page on the Upscayl official website showing a "404" error? How do I download and start using Upscayl from GitHub?

Hi @2573054412a-cmyk! I'm Dosu and I’m helping the upscayl team.

The easiest way to download Upscayl directly from GitHub is via the Releases page: https://github.com/upscayl/upscayl/releases/latest [1]. There you'll find installers for all platforms:

• Windows – .exe installer
• macOS – .dmg download (also available via Homebrew: brew install --cask upscayl)
• Linux – Flatpak, AppImage, Snap, or AUR packages

One requirement: Upscayl needs a Vulkan-compatible GPU to run [1].

Regarding the website 404, I didn't find any tracked issue for that, but the GitHub releases page above is the most reliable source for downloads regardless.

I wasn't able to read the text in your screenshot clearly. Could you paste the exact error message text so I can help more precisely?

That said, the most common errors in Upscayl are typically GPU/Vulkan-related. Here are the likely culprits:

• vkCreateInstance failed -9 — Your GPU doesn't support Vulkan 1.3, which Upscayl requires. This is the most frequently reported error, especially with older or integrated GPUs [1].
• Invalid GPU Device — A GPU compatibility issue during upscaling, which can happen even with dedicated GPUs [2].
• vkQueueSubmit failed -4 — Often occurs around 89% progress, related to GPU device loss or driver issues [3].
• vkAllocateMemory failed -2 — Specific to some AMD integrated GPUs where Vulkan selects a too-small memory heap [4].

Recommended steps:

1. Make sure your GPU drivers are fully up to date
2. Confirm your GPU supports Vulkan 1.3 (most modern NVIDIA, AMD, or Intel Arc cards do)
3. If your hardware isn't compatible, you can use the online version of Upscayl as a workaround

Please share the error text and your GPU model so I can narrow it down!

Displayed as "vkEnumeratePhysicalDevices failed 5 Error:Invalid GPU Device" @dosu

The error vkEnumeratePhysicalDevices failed 5 — Invalid GPU Device means Vulkan can't detect your GPU. This doesn't necessarily mean your GPU is incompatible — it often means something is blocking access to it.

If you're on Linux (especially Ubuntu with the Snap version): This is a frequently reported issue where AppArmor restrictions in the Snap package block Vulkan from accessing your GPU [1]. The fix is to switch to the Flatpak version from Flathub, which has been confirmed to resolve this for multiple users [1].

General troubleshooting steps [2]:

1. Update your GPU drivers and restart your computer
2. Try setting the GPU ID manually to your discrete GPU in Upscayl's settings
3. Verify your GPU has Vulkan support using VulkanCapsViewer
4. If nothing works, try switching to a different install method (Flatpak or AppImage instead of Snap)

Could you share what OS and GPU you're using, and how you installed Upscayl? That'll help narrow things down further.
