Question Error and security warning on using Linux Mint

I have installed the unity hub from the repo the same way they recommend to for Ubuntu and after starting it with this command

unityhub

the program seem to have started fine but I got this message

libva error: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so init failed

Checking for update

Error: Error: ENOENT: no such file or directory, open '/opt/unityhub/resources/app-update.yml'

(electron) Security Warning: A WebContents was just created with both webviewTag and contextIsolation enabled.  This combination is fundamentally less secure and effectively bypasses the protections of contextIsolation.  We strongly recommend you move away from webviews to OOPIF or BrowserView in order for your app to be more secure

I saw a similar warning on the forum, but it was from before 3.1.1 and the recommendation was to download beta 7, which I don't think is relevant

Thanks

 

got the exact same errors but 3 months later. did you find a solution?
best wishes
