Download Models in AppImage ERROR EACCES: permission denied, mkdir

[dankarthik25]

I am using Linux mint and new to LLMs
I am able to run LM Studio App Image with changing permissions chmod +x LM-Studio*.AppImage
but when i want to download LLM models it is giving error :

EACCES: permission denied, mkdir '~/.lmstudio/models/lmstudio-community/DeepSeek-R1-0528-Qwen3-8B-GGUF'

I thought may be some issuse with sandbox and
i have used ./LM-Studio*.AppImage --no-sandbox --unsafe-perm=true

I thought there might be issuse with local npm permission and change the settings as
https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

I have tried different methods
https://www.tecmint.com/lm-studio-run-llms-linux/

chmod u+x LM_Studio-*.AppImage
./LM_Studio-*.AppImage --appimage-extract
cd squashfs-root
sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox
./lm-studio

Still i am getting error

One odd thing i notice is when LM Studio load for first time it is able to download files like

• llama.cpp-linux-x86_64-valkan-avx2(1.58.0)
• hormony-linux-x86_64

in dir ~/.lmstudio/extensions/backends/

But when i select model it is showing Error can some one tell me what is the issuse, where should i ask for help?
