I ran into to issues.. 1st, running command - sudo apt install -y ./jan.deb. at the end it had an error: Download is performed unsandboxed as root as file '/home/kev/jan.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
The second was after opening downloading the the model. I ran the app and just typed, Hello and it returned an error. Failed to fetch Something's wrong. Access troubleshooting assistance now.
I'm not a linux pro, but I am thinking it is tied to the first issue.
I also tried to do the DL from the home page but pnce the zip package is extracted the three items can not find anything to control them.
Any assistance would be awesome. I have been waiting for this AI for a few years and I'm excited to try it out.
Thx,
Kevin
Hi,
I recently installed Jan on Ubuntu, and it is working fine. I also encountered the message "N: Download is performed unsandboxed as root as file ... pkgAcquire::Run (13: Permission denied)", but it doesn't cause any issues.
I successfully downloaded the model for testing, and it is responding to my questions.
If you're experiencing issues, perhaps you downloaded a large model that doesn't fit into your system's memory. Try downloading a smaller model, such as Llama 3.2 1B Instruct Q8.
I also recommend reading the Troubleshooting section in the Jan documentation.
