Known bugs[edit]

VirtualBox Specific[edit]

ATA Freeze[edit]

If you see the following error and freezing.

433.348893] mptscsih: ioc0: attempting target reset! (sc=ffff81021b950940)
433.348896] sd 0:0:0:0: [sda] CDB: ATA command pass through(16): 85 08

433.605026] mptscsih: ioc0: target reset: SUCCESS (sc=ffff81021b950940

It's a known issue.
VirtualBox upstream bug report: https://www.virtualbox.org/ticket/10031
Cannot be fixed by the Whonix team. Patches required. Hardware specific.
It has been reported that running form internal hdd works better than running from external devices.
A workaround might be "avoid high load on your host operating system". If this bug causes a lot issues to you, your only option is to switch to another platform.


Non-Qubes-Whonix means all Whonix platforms except Qubes-Whonix. That includes KVM, VirtualBox and Physical Isolation.

Suspend / Hibernate Issues[edit]

Short: Better do not suspend or hilbernate your computer or Whonix VMs while Whonix is running.

Long: Network Time Syncing, Troubleshooting#Clock Fix. [1]

Mounting (CD/DVD) Devices[edit]

Device auto mounter is broken.

See if Start menu -> System Settings -> Removable Media helps.

You can use the following workaround.

sudo mkdir /mnt/cdrom
sudo mount -o ro /dev/cdrom /mnt/cdrom/

Using the ro flag will mount the CD/DVD read-only. If you are not mounting a CD/DVD, then you can drop the "-o ro" parameter.

Forum discussion:

Help fixing this bug is welcome! (ticket)

VLC / Video Player Crash[edit]

You can use this workaround.

VLC -> Tools -> Preferences -> Video -> Output -> X11 -> Save

Proxychains Tor Browser Issue[edit]

If you want to use Tor Browser in conjunction with proxychains for the connection scheme user -> Tor -> proxy -> internet,
this currently won't work. For more information, see here.

"apt-get source package" will show "dpkg-source: warning: failed to verify signature"[edit]

This is not a security issue, but only a warning. See here for more information and read the entire thread.

You can get remove this warning message with the following workaround below.

1. Modify /etc/dpkg/origins/default

sudo unlink /etc/dpkg/origins/default
sudo ln -s /etc/dpkg/origins/debian /etc/dpkg/origins/default

2. Download the Source Package

apt-get source package

3. Undo Afterwards to Prevent Unexpected Issues

sudo unlink /etc/dpkg/origins/default

sudo ln -s /etc/dpkg/origins/whonix /etc/dpkg/origins/default

  2. Whonix doesn't use network manager to either manage eth0 or eth1. We do not want to port to network manager at this point, because there is no reason besides this issue. For one reason, because ifupdown works well with Whonix for a long time and is well tested. It is unclear if network manager, specifically cli, is ready for prime time yet. What network manager reports is that it does not manage these devices. It's not an error. Just an information. What we would like to do would be hiding that systray item by default. Or suppress that information. Or not starting that systray by default. Because that would cause less confusion. Network manager is installed to make it easier for users setting up VPNs using its graphical user interface.
    All attempts so far fixing it have failed. Help required for fixing it.
    Long standing known issue.
