STEP 1:Īfter making a snapshot, start your Ubuntu virtualbox back up, open up the terminal, and execute the following: sudo apt update Shut Down your Ubuntu Virtualbox, and make a Snapshot! That way if anything goes wrong, you can restore your working image. Luckily I made a snapshot before I executed the solution, so I rolled it back and did this instead: BEFORE YOU BEGIN: After following juhist's answer my ubuntu virtualbox was completely frozen after rebooting (keyboard and mouse wouldn't work after ubuntu logged in). I had the same problem that sam had (the 3rd comment in juhist's answer).

Interface: IExtPackManager Įven after power off of VM's and restarting the host OS, I get this similar error code. Failed to install the Extension Pack /home/aniket/Downloads/Oracle_VM_VirtualBox_Extension_Pack-5.0.20-106931.vbox-extpack.įailed to load the main module ('/usr/lib/virtualbox/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/linux.amd64/VBoxPuelMain.so'): VERR_FILE_NOT_FOUND - /usr/lib/virtualbox/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/linux.amd64/VBoxPuelMain.so: undefined symbol: RTLogRelGetDefaultInstanceEx. While installing virtual box extension pack, there were two VM's running and i got this popup. Also i need to mount the USB to my virtual machine and not my host OS, so i downloaded extension pack version 5.0.2 for Vbox-5.0. I purchased a network card to give a separate network to my virtual machine.
