[Solved] Virtual machine cannot boot after installing official extension pack.

[Felix Wang]

I use VIrtualBox 6.1.4 r136177 on Manjaro Linux 19.0.2 with kernel 5.5.8-1. I emulated a Windows 10 (Developer edition, WinDev2003Eval) operating system downloaded from Microsoft's official website as a .ova file.

In order to access the laptop camera in the virtual machine, I downloaded Oracle's VirtualBox extension pack: Oracle_VM_VirtualBox_Extension_Pack-6.1.0_RC1.vbox-extpack. I firstly tried to install this extension pack graphically, however, I got this error:

. So that I used this command to install manually:

Code: Select all

sudo /usr/lib/virtualbox/VBoxExtPackHelperApp --stdout /dev/stdout --stderr /dev/stderr --elevated install --base-dir /usr/lib/virtualbox/ExtensionPacks --cert-dir /usr/share/virtualbox/ExtPackCertificates --name 'Oracle VM VirtualBox Extension Pack' --tarball /home/felix/Downloads/Oracle_VM_VirtualBox_Extension_Pack-6.1.0_RC1.vbox-extpack --sha-256 0e060ef651ba691ae7a24a9619cb4a9b4bec6a55922d05f1ad6861b1d05da2df

. It should be noted that I changed the stdout and stderr flags to /dev/stdout and /dev/stderr. This time the installation was completed successfully.

However, when I tried to boot my virtual machine afterwards, I always got this error:

. More detailed information can be found in uploaded file VBox.log.3. (I changed its extension name to .txt in order to upload it.)

What is the reason that caused this issue and how to repair it? I really need to use the functions provided by the extension pack.

Thank you for any reply .

Where did you get the link for that old extpack download? The extpack needs to match the version of VirtualBox.
Please just use the download link from https://www.virtualbox.org/wiki/Downloads which will give you the correct 6.1.4 version of the extpack.
