Frequently Asked Questions

Why doesn’t SDA work after I reboot my machine?

If you have disk encryption enabled, the password is unfortunately required to decrypt the disk. In this case, you can login to your machine for the first time by declining the SDA request, and typing your password in manually.

To check if you have disk encryption enabled, type:

ls -A /home | grep ecryptfs
If the directory .ecryptfs exists, you do have disk encryption enabled.

Why does my Bluetooth keeping turning off and on?

There is some strange thing that arises when the phone and the computer are paired. The only fix that we are currently aware of is to unpair the phone. To do this, first kill the SDA service:

sudo service sda-delegate stop
Then unpair the device in your Bluetooth Settings,

and restart the SDA service:

sudo service sda-delegate start

Why isn’t SDA working when I type sudo or try to unlock my machine?

This is likely because you have not selected a username, or usernames, to associate with SDA. Please configure this using our GUI, as shown below:

Why can’t I install SDA from apt-get?

If you are getting the following error:

The following packages have unmet dependencies:
 sda : Depends: sda-delegate-service but it is not going to be installed
       Depends: sda-pam-module but it is not going to be installed
       Depends: sda-websocket-service but it is not going to be installed
       Depends: sda-gui-config but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
it is because we require some packages from the universe/multiverse repositories. You can fix this by typing the following:

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"

Why isn’t Bluetooth working?

If you just installed SDA on 18.04, it’s possible that the bluetooth service simply needs to be restarted:

service bluetooth restart
