The following steps summarize basic troubleshooting instructions, which are described in greater detail below. In basic terms:

  1. Non-Qubes-Whonix only: Verify the Whonix virtual machine images if this has step has not previously been completed.
  2. Ensure the virtual machine images have been imported into a supported virtualizer.
  3. Check if Tor Browser works on the host.
  4. Check if other virtual machines have Internet connectivity, such as newly created ones or those from a different vendor.

Information pertaining to these points should be included in any support request or bug report.

Troubleshooting Steps[edit]


It is recommended to first test if the host Internet connection is functional by using ping. [1] On the host, run.


Check the date and time.


The following command should not show any errors. [2]

sudo dpkg-reconfigure -a

The following command should be silent and not show any errors or output at all. [2]

sudo dpkg --configure -a

Next attempt to retrieve all available updates.

sudo apt-get update
sudo apt-get dist-upgrade

Download the Tor Browser Bundle from and test if it is working on the host. To do this, follow one of the methods outlined in Non-Whonix Tor Browser.

If the Tor Browser Bundle is not functional on the host, then Whonix is unlikely to work either. It is recommended to have a recent Tor Browser Bundle version installed at all times. This way users can test if they live in a censored area or not and whether Tor is blocked by the ISP. Further, if (private) (obfuscated) bridges are necessary for Tor Browser Bundle functionality on the host, then Whonix will similarly require them.

Whonix Network Connectivity Problems[edit]

If networking is unavailable inside Whonix, then try:

  1. Installing an operating system in a non-Whonix virtual machine or downloading a regular image without Tor enforcement.
  2. Testing network functionality in a freshly downloaded non-Whonix virtual machine.

If networking is still not functional, then Whonix will not work either. The user must first resolve this issue, which might require re-installation of the virtualizer, followed by a reboot and further connectivity test.

If networking is functional, then users should note that networking is working in non-Whonix VMs as part of the support request or bug report.


Run whonixcheck to verify that the Whonix system is up-to-date and that everything is in proper working order.

Clock Fix[edit]

The first step should be completed on the host to ensure the host clock is set to the correct time.

On the host (Qubes-Whonix: dom0), run the following command to report the time in UTC.

date -u

The output should be similar to the following.

Sun Jul 14 04:30:44 UTC 2018

To set the correct time in Whonix-Gateway (sys-whonix), run the following command with the correct date and time parameters.

sudo date --set "Sun Jul 14 04:30:44 UTC 2018"

Tor should work once correct clock values are set, but that can be manually tested with whonixcheck.

Next restart sdwdate.

sudo service sdwdate restart

If Tor is still not functional, try restarting Tor.

sudo service tor restart

Clearnet Connectivity Test[edit]

Users can check if a non-torified, non-anonyomus, direct connection to is functional. [3]

On Whonix-Gateway, run.

sudo -u clearnet UWT_DEV_PASSTHROUGH=1 curl --tlsv1.2 --proto =https -H 'Host:' -k


Connectivity Issue[edit]

Complete the following steps:

  1. Shut down sys-whonix.
  2. Change the sys-whonix NetVM setting from sys-firewall to sys-net.
  3. Restart sys-whonix.

This procedure might help, but should not be considered a final solution. [4]

Low RAM Issues[edit]

When adequate RAM is unavailable to meet the requirements of the Whonix VMs, issues can develop that can cause VM to become unusable. There are common factors that can contribute to low RAM issues in Whonix VMs.

  • Unnecessary processes running and/or multi-tasking on the host OS.
  • Multiple Browser tabs open.
  • Unnecessary processes running in the Whonix VM.
  • Allocating more RAM to the Whonix VM than what is available.[5]
  • Insufficient RAM allocated to the Whonix VM.
  • Other non-Whonix VMs running.

While insufficient RAM can cause a variety of issues there are certain behaviors that are commonly associated with low memory resources.

  • Applications are slow or unresponsive.
  • The Virtual machine, mouse and/or keyboard may freeze.
  • Window staggers or jumps when scrolling.
  • Issues become worse when opening additional browser tabs or starting new processes.
  • General performance issues.

If additional memory is needed for the virtual machine, users can free up resources and/or add more RAM to the virtual machine.

Free up additional memory resources.

  • Terminate any non-essential processes on the host.
  • Shutdown any non-essential VMs.
  • Shutdown and/or close non-essential processes and browser tabs in Whonix VMs.
  • (Non-Qubes-Whonix only!) If users are experiencing low memory issues in the Whonix-Workstation, additional resources can be freed by reducing RAM in Whonix-Gateway VM by using rads.

Add additional RAM to the Whonix VM.


Note:To add RAM in VirtualBox the VM must first be powered down.

  • Virtual machine -> Menu -> Settings -> Adjust Memory slider -> Hit: OK


1. Shutdown virutal machine.

virsh -c qemu:///system shutdown <vm_name>

2. Increase maximum memory

virsh setmaxmem <vm_name> <memsize> --config

3. Set actual memory

virsh setmem <vm_name> <memsize> --config

4. Restart virtual machine.

virsh -c qemu:///system start <vm_name>


  • Qube Manager -> VM_name -> Qubes settings -> Advanced -> Max memory: mem_size


  1. For example, ping, ping and so on.
  2. 2.0 2.1 This process can be lengthy.
  3. This test only uses TCP and not DNS.
  4. This procedure was useful for Qubes-Whonix R3.2 users, although the Qubes bug report is now resolved:
  5. Adding more memory than what is available will prevent the VM from booting.
