    After several days of finally figuring out how to install VMs in 6.8 last night (separate thread),

    all of the VM's which were running fine last night now throw the following error:

     

    noVNC encountered an error:

     

    SyntaxError: import not found: supportsImageMetadata

    http://192.168.0.250/plugins/dynamix.vm.manager/novnc/core/display.js:11:9

    noVNC

     

    Diagnostics attached.

    Unfortunately there is nothing in the logs that specifically indicates a problem or error.  Where are you seeing the message?  Does it happen when you try to start the VM or only when you try to use noVNC?  What if you use a regular VNC client to connect, does that work?  I tried this on a test rig and noVNC is working fine for me.  Any additional details or testing you can share with us would be appreciated.

    The error happens when clicking  "VNC Remote" in the drop-down menu

    after having started the particular VM.  (Happens for all VMs).

     

    It happens in Windows Edge and Linux Firefox browsers. 

    Resolved when I reverted to 6.7.2

    The noVNC package was updated in 6.8 - very well could be browser caching issue.  Please try @FlynDice suggestion of clearing browser cache and let us know if that fixes it.

    Clearing the cache worked.  Thanks.

    @limetech Thanks for all your help looking into this ! 

     

    I have re-loaded 6.8 and am trying to methodically go through steps to see if there is a specific trigger that leads to the behavior.  Last time this all happened after about 24 hours (or perhaps 10 or so VM start/stops).  Will report back in a few days.

    Here is the status:

     

    I am currently unable to re-create the original issue.  However have discovered a problem that perhaps may have triggered it previously.

     

    I can start/stop and edit Ubuntu 18.04 , 19.04 VMs with no issues. These were installed under 6.7.2, and kept after the Upgrade to 6.8

     

    Under 6.8 I was successful in installing Ubuntu 19.10 VM, and it runs fine.  However, I cannot edit that VM

    (the VM is stopped when editing).  Trying to edit a property (memory, CPU cores) then clicking apply results in:

    1. The GUI never returns - it just hangs with the buttons greyed-out.

    2. Trying to then start 19.10 results in it being dead - it goes directly into grub2 screen with no valid image found and asking to do a new install from scratch.

    I repeated these steps several times.

     

    6.7.2 was never successful in installing 19.10 (nor upgrading 19.04 to 19.10 which fails in the middle of the upgrade becoming unbootable the same way), so 6.8.0 is a wonderful improvement there.

     

    - Tom
