From PostX 0.6 to 0.7 – Upgrading guide.

This guide is for upgrading the PostX Gnu/Linux to 0.7 version. As of 3rd of January 2021 Debian Buster is having some issues with grub-efi and grub.cfg generation. This leads to failures when generating new images. Given the previous, the more manual way of upgrading PostX Gnu/Linux was chosen at this time.


  • Disable secure boot before attempting to install (Bios).
  • Possibly disable legacy boot (Bios).
  • Before proceeding read the section: Know issues – AMD from this document.

To begin get PostX Gnu/Linux 0.6 and install it.

0.6 release notes and guide.

When that is done then proceed with the instructions below. Remember that you do everything with your own responsibility and if things get broken it is your responsibility to fix them. Always backup anything important before proceeding.

Disclaimer: Upgrade changes system structure. Make sure you copy all important configs and customizations before proceeding. If something goes wrong it is user’s responsibility to fix the issues and deal with possible damages.

Notable changes, excluding version upgrades:

– Text editor will change from Metapad to ++Editor.

– ImageViewer is added.

– Quick Terminal is back as primary terminal.

After upgrade, the Openbox menu will be out of date, since programs have changed. See, step 4.

Upgrading steps

1. Enable repository :

sudo nano /etc/apt/sources.list.d/postx.list

#Techtimejourney repo

Quick password based file encryption with ccrypt.

Gnugpg is in many ways the champion of encryption on Linux(personal opinion).

Sometimes there is a need to do quick password based encryption. This can be achieved with ccrypt.

Ccrypt should be available on standard Debian/Ubuntu or Centos8 repository resources.

I use Debian base here, but the steps should be similar on Centos8 or equivalent.

sudo apt-get install ccrypt -y

echo “I am going to be encrypted” >> ./example.txt

ccrypt ./example.txt

At this point a password for the encryption is needed. For this example, I used: hello.

After the encryption, my file will be found as: example.txt.cpt.

If I now try to read this cpt file, there will be nothing that can be understood on the output.

To decrypt and make the file readable again: ccdecrypt ./example.txt.cpt

After decryption, the example.txt is again found as a clear text file.
