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 is 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[edit]

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

Suspend / Hibernate Issues[edit]

Short: Avoid suspending or hilbernating the computer or Whonix VMs while Whonix is running.

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

Mounting (CD / DVD) Devices[edit]

If the device auto mounter is broken, see if Start menu -> System Settings -> Removable Media helps.

The following workaround can be used.

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

Using the ro flag will mount the CD / DVD in read-only mode. If a CD / DVD is not being mounted, then drop the "-o ro" parameter.

Help fixing this bug is welcome! (ticket)

VLC / Video Player Crash[edit]

The following workaround can be used.

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

Network Manager Systray Unmanaged Devices[edit]

Proxychains Tor Browser Issue[edit]

Using Tor Browser in conjunction with proxychains for the connection scheme: User -> Tor -> Proxy -> Internet
doesn't currently 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. Read the entire thread here for more information.

This warning message can be removed 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
  1. https://github.com/QubesOS/qubes-issues/issues/1764
  2. Whonix doesn't use network manager to manage either eth0 or eth1. It is unnecessary to port to network manager at this point, because there is no reason besides this issue. Ifupdown has functioned admirably in Whonix for a long time and is well tested. It is unclear if network manager, specifically cli, is ready for prime time yet. Network manager is simply reporting information that it does not manage these devices; this is not an error. To reduce confusion, the ideal Whonix default would either: prevent the systray item starting, hide the systray item, or suppress the information being presented. Network manager is installed so users can easily setup VPNs with its intuitive graphical user interface.
    All attempts to fix this long-standing issue have failed. Help is welcome to fix it.
