I just downloaded the latest beta and when it tries to download the Viritualbox Extension Pack I get "The network operation failed with the following error: During network request: Url not found on server.

Thoughts?

What does "it tries to download" mean?

VirtualBox does not download the extension pack. You do that. I don't know where you're seeing that download link, because the one I see in the Downloads area is 6.1.0_BETA1/Oracle_VM_VirtualBox_Extension_Pack-6.1.0_BETA1-133315.vbox-extpack.

Sometimes it tries, I've seen it happening. I have yet to identify the conditions, mostly because I download VirtualBox+ExtPack in one-go, and then I use my command-line tool to uninstall the previous one and install the new one, so it doesn't have a chance to tell my to download the ExtPack too often...

Just as 'mpack' said, download it and install it manually. Since you're in the beta testing, I would download the latest 6.1.0b1, disguised as a "Development snapshot" from the Test builds area.

I'll describe a typical workflow from my own experience that somehow matches all three statements:

On a macOS 10.13.6 host, VirtualBox 5.2.x is installed. When the VirtualBox GUI app is being started, it checks for updates and finds VirtualBox 5.2.y (y > x). I manually download and install VirtualBox 5.2.y and start the VirtualBox GUI app. The GUI app prompts me that I have an old Extension Pack Version 5.2.x installed, and offers to download and install the Extension Pack 5.2.y, by clicking a few buttons. In consequence, while I have triggered the download, the VirtualBox GUI app has performed the download.

PS: I don't know, if VirtualBox 6 exhibits the same behavior.

Sorry all. so when I start VirtualBox it says "You are running a prerelease version of VirtualBox. This version is not suitable for production use." Clicking ok then bring up, "You are running an outdated Extension Pack, click to download" . Clicking download then comes up with the with the error: unable to get resource

Confirmed. Known issue, talked it over with the developers over at IRC...

I download the r133315 beta and extension pack and the VM's will not boot... Get the following error

Failed to open a session for the virtual machine Kali-100.

The device instance structure version has changed.

If you have upgraded VirtualBox recently, please make sure you have terminated all VMs and upgraded any extension packs. If this error persists, try re-installing VirtualBox. (VERR_PDM_DEVINS_VERSION_MISMATCH).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I removed the previous version of VirtualBox... Any ideas...

You are installing different versions of the main program and the Extension Pack. Make sure they do.

BTW 'akaempf', you should definitely read the thread: Do not hijack other threads, create your own. Choose your title carefully. Your error message wasn't even close...

After lots of head scratching I've found the cause... a glitch in the release process of 6.1.0_BETA1 it seems. Don't know how, but a symlink in the download directory was lost (or never created), and that symlink is vital for the operation of the extpack download feature in the GUI.

This is fixed now, I've tested that the GUI can download the beta1 extpack without trouble.
