This is an optional part of the Zero Trace Pen guide. Please only follow the instructions here when you actually need to install further apps. It is not necessary to install additional software because the Pen already has everything you need to be installed.
If those items were not checked, then reboot so that the settings can take effect. If you needed to reboot, enable persistence and assign an administration password again. Start a root terminal (Applications -> System Tools -> Root Terminal) Type the following commands:
apt-get update(this will take a while, probably 5 to 10 minutes) In this example, we are going to install the following package: GPA (The GNU Privacy Assistant – a familiar PGP client) Type the following commands:
apt-get install gpa(enter y to confirm the installation of the package)
cd /live/persistence/TailsData_unlocked
gedit live-additional-software.conf Add the following line to the empty file:
gpa
Save the file and exit gedit.
Normally when you install software on Pen using apt-get, it is erased when you shut down and you have to re-install it the next time you boot.
Using the above apt persistence settings, the downloaded software is saved locally. By listing items in the “live-additional-software.conf” file, the system will automatically unpack and install them on boot.
The packages are unpacked by a separate process so that the boot-up time is not extended too much. A status message will pop up when the system is done installing the software reading
