Can't update Lora Manager

[azra1l]

LoRA Manager Version

• Version: v1.0.6

Environment Information

• Operating System: Windows 11
• Browser & Version: Chrome 140.0.7339.186

Issue Description

I can't update the lora manager custom node. Neither via comfyui, nor via the update button in lora manager. If i try, i get an error message that the file "ComfyUI\custom_nodes\comfyui-lora-manager\cache\download_history\downloaded_versions.sqlite" is in use and can't be accessed. I renamed the file, it just created another one and the problem persists. This already happened for the 1.0.7 update. I was able to install updates for this custom node before.

Steps to Reproduce

Start Update
Get error message

Expected Behavior

I expect the update to complete successfully.

Thanks for the detailed report. This has been fixed. The update process tried to delete the cache/ folder while the SQLite database inside it was still open, which fails on Windows.

For now, since the in-app update can't bypass itself, here's the recommended workaround:

1. Fully shut down ComfyUI (make sure the Python process is stopped)
2. Download the latest release ZIP from Releases page (v1.0.10)
3. Extract and overwrite the files into ComfyUI/custom_nodes/comfyui-lora-manager/
4. Important: Keep your cache/ folder and settings.json. Only overwrite everything else.
5. Restart ComfyUI

Once you're on v1.0.10, future in-app updates will work normally.

Let me know if anything comes up!
