[SOLVED] No Console Access via noVNC - Unable to create RFB client

[ulf.kosack]

Hello,

today I updated my PVE Installation from pve-kernel-2.6.32-39-pve to pve-kernel-2.6.32-40-pve via aptitude safe-upgrade. After Reboot I deleted the old kernel pve-kernel-2.6.32-34-pve (like a couple of times in the past).

Proxmox Management GUI is still running, but I can't get console access via noVNC. Access via VNC is available.

The error message in noVNC console is:

Unable to create RFB client -- TypeError: Util.set_defaults is not a function

Package versions:

How can I get console access via noVNC?

Thanks

You cannot use aptitude safe-upgrade you must use apt-get dist-upgrade since a version of proxmox comes bundled as number of packages.

 

[ulf.kosack]

There are no more packages:

~# aptitude dist-upgrade
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.

~# aptitude full-upgrade
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.

I will compare no the packages with a second installation.

Did you run apt-get update before apt-get dist-upgrade? (note apt-get not aptitude)
Did you clear your browser cache after upgrade?

 

[ulf.kosack]

Yes, I did. And I did it again:

I've compared my two instance (one with subscription, one without). The noVNC error occure on the instance without subscription (test environment).

The differences I see are ...
on the server without subscription:

ii  novnc-pve                        0.5-3                         amd64        HTML5 VNC client
...
ii  proxmox-ve-2.6.32                3.4-160                       all          The Proxmox Virtual Environment

on the server with subscription:

ii  novnc-pve                        0.4-7                         amd64        HTML5 VNC client
...
ii  proxmox-ve-2.6.32                3.4-159                       all          The Proxmox Virtual Environment

On the server with novnc version 0.4-7 noVNC is functionally.

Please try to clear the browser cache.

 

[ulf.kosack]

Browser Cache??? Im on the ssh console.

 

[ulf.kosack]

one moment. browser cache for noVNC. To fast typing :-(

 

[ulf.kosack]

Great stuff. Thanks for telling me the basics . noVNC connection is available again.

I'm getting this error when accessing NoVNC on pve 4.0 gui.

"Unable to create RFB client -- ReferenceError: inflator is not defined"

Just got this same error when login using host-name (not FQDN address.) No problem with IP address login though. Odd. Could it be that Proxmox now demands FQDN on the address field?
