Unable to install Extension Pack

Post by irishjd »

I am running RHEL 6.8 with Virtual Box Version 5.1.18 r114002 (Qt5.6.1). Every time I try to install Extension Pack version 5.1.18-114002, I get this error:
Failed to install the Extension Pack /home/md2mmub/Desktop/Oracle_VM_VirtualBox_Extension_Pack-5.1.18-114002.vbox-extpack.

The installer failed with exit code 1: **

ERROR:pkexec.c:128:pam_conversation_function: code should not be reached.

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ExtPackManagerWrap
Interface: IExtPackManager {edba9d10-45d8-b440-1712-46ac0c9bc4c5}
Any ideas?

Thanks,
Jon

Have you made sure that the checksum matches, i.e. that you don't have a corrupt download?

Hello,
Yes, I downloaded the hash valuse and compared them to the hash of the downloaded file, and they match, so the download should be good.

How did you try to install the ExtPack? Have you tried to install it from within VirtualBox's preferences » Extensions? It seems that the installed "pkexec" in your system is failing for some reason. I'd start digging there...

I get the exact same error when trying to install it via /Preferences/Extensions

Did you manage to fix your problem?

Can you rule out the Secure Boot issues?

I work on Ubuntu 16.04 with Secure Boot enabled and get exactly the same error when trying to install the Extension Pack.

Code: Select all

The installer failed with exit code 1: **
ERROR:pkexec.c:138:pam_conversation_function: code should not be reached.

I never did get this working. I ended up using KVM instead of Virtualbox. That being said, I have recently build a RHEL 7.4 system, and I was able to install Virtualbox and extensions without any issues.
