As I wrote above: In difference to you I download VB from the Oracle download site. I think, that this makes the difference. 4.3.34 at now.
I think, that is a license issue. VB is GPL, but the extension package is not. Also the extension package may in difference to the VB base not be redistributed
, this is the reason, that it is not available iin the repos. And - my guess - to be on the safe site, the message I described (inclusive the download option) has been removed for the repo package.
Most likely you wouldn't have come into the trouble with the Oracle version, because you would have been noted, to update the extension pack - provided, that you launch after a VB update at first the VB manager, before launching any VM. If you read the first 2 lines of the OP in the linked VB forum thread you find, that this user did also have VB installed from the official repo (otherwise he would not have got the update via the system's software updater), so he had also not been notified.
Instead of downloading the DEB-file you could also use a PPA provided by Oracle. I recommend always the manual download, because it gives more control, if and when I install an update. My long-time experience with VB confirms, that it is a good idea, to wait and check the VB forum after some days, after a new version has been released. The Oracle version has the option to check regularly, if a new version does exist; you can even configure this in some details.
Doing this way I have never been in trouble with my VMs since many years.
