QT_QPA_PLATFORMTHEME is not set, and setting it didn't make any difference to this issue. But it doesn't make any difference here (nor does setting it when physically on the server machine result in the issue showing up there). (VirtualBox is not installed on the client, which is not powerful enough to run the VMs in question.) LIBGL_ALWAYS_SOFTWARE=1 is set because it fixed similar issues in other Qt 5 apps. VirtualBox version on the server is 6.0.24 and changing that is not currently an option. When running VirtualBox VMs, there is a lot of display tearing on the VM screen and often the VM screen stops updating.īoth client and server machines are running Xubuntu 20.04. In the VirtualBox manager interface, every visible "section" of the GUI is cut in half and one of each half does not redraw in real time. I can provide as much aditional information as you want.So I'm trying to set up remoting into another machine over ssh -X on the same Wi-Fi LAN so that I can use VirtualBox on the server machine from the client machine. I can create a Ubuntu Server 20.4 image but not a Ubuntu Server 20.4.1. I have tried with the last version of Packer, Packer 1.8.0, and the result is the same. Now, I have tried to create a Virtualbox Ubuntu 20.04.4/.3/.2/.1 guest using packer 1.5.6 but Packer can't create the image because once the installation is done, after rebooting the SSH server does not answer (the packer log error says: SSH handshake err: Timeout during SSH handshake). 'sed -i "s/dhcp4: true/&\n dhcp-identifier: mac/" /target/ etc/netplan/ 00-installer- config. sed -i 's/^#*\(send dhcp-client- identifier\ ).*$/\1 = hardware /' /target/ etc/dhcp/ dhclient. Two years ago I was able to create a Virtualbox Ubuntu 20.04 guest in a Windows 10 host with Packer 1.5.6, using an unattended installation.
