Cannot Run TimeMachine on my Machine

[maryammsd]

I cloned the repo on a remote server and tried to run the commands given below to analyze an application.

./exec-single-app.bash ../X.apk 0 droidtest/timemachine:1.0 1800 ../X_output

However, I get the following error:

• true
• echo 'adb not connected!'
  adb not connected!
• adb disconnect 127.0.0.1:6000
• adb connect 127.0.0.1:6000
• timeout 2 adb -s 127.0.0.1:6000 wait-for-device shell exit 0

How can I solve it? What could be the reason behind?

Can you check if your virtualbox has been installed properly? Most likely, it is because the vm does not work well due to versions issues with your operating system and virtualbox.

What you can do is to manually login in a docker container and check out if the created vm works well.

Just posting an earlier (deleted?) solution. Not sure if it is useful.

I have the same problem

insmod: ERROR: missing filename.
WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-dkms package and the appropriate
headers, most likely linux-headers-generic.

 You will not be able to start VMs until this problem is fixed.
Virtual machine 'Android7_1' is created and registered.
UUID: 007f6612-0911-494e-b492-b7fc2540f79c

WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-dkms package and the appropriate

I try to reinstall different version virtual box, but not work.
how can i solve it ？

Later

I solve the problem by this steps:

# close security boot.
sudo apt install virtualbox-dkms
sudo dpkg-reconfigure virtualbox-dkms
sudo dpkg-reconfigure virtualbox
