Support Status of the DBLab Distributions

All of the base systems of the DBLab distributions have reached end of life (Ubuntu 13.10: July 2014, Ubuntu 12.04 LTS: April 2017, Ubuntu 14.04 LTS: April 2019). Security updates are no longer published for them, and their package repositories have been moved to old-releases.ubuntu.com.

When a DBLab distribution is used, run the following commands to switch the repository to the archive server. Otherwise, apt-get fails to download packages.

sudo sed -i -e 's|archive.ubuntu.com|old-releases.ubuntu.com|g' -e 's|security.ubuntu.com|old-releases.ubuntu.com|g' /etc/apt/sources.list
sudo apt-get update

For a machine that is connected to the Internet, install a currently supported release (for example, Ubuntu 26.04 LTS, released in April 2026) and install the software packages listed on this Web page with apt. The DBLab ISO image files are kept available for offline use, for reproducing past experiments, and for virtual machines that are isolated from the network.

Overview, System Settings, Boot Procedure, and Software List

Summary

DBLab is remixed system derived from the Linux operating system

The DBLab distributions are remixed systems derived from the Linux operating system (OS). Each remixed system consists of system settings, software packages, and additional software that is not contained in the base system (they are listed below in this Web page). The remixed system derived from Linux OS is set up as follows:

  1. Install Linux OS.
  2. Update Linux OS.
  3. Set up private repositories to install additional software packages.
  4. Install additional software packages.
  5. Install other freeware that is not packaged.
  6. Remove unredistributable software from the remixed system. The original Linux OS may include unredistributable software.
  7. Adjust the system settings, such as Internet connection, language, and keyboard.
  8. Adjust the desktop settings, such as the login screen, desktop layout, and desktop window manager settings

The goal of the DBLab distributions is to provide an all-in-one desktop system based on the Linux OS with database software and other related software tools and programming libraries. The DBLab distributions contain database management system software (SQLite 3, Redis server and client, MySQL client library), a database software tool (SQLiteman), text editors (Leafpad and GNU Emacs), a binary editor (GHex), terminal software, additional programming languages (C, C++, Fortran, Java, JavaScript, jQuery, Python, Tcl/Tk, Ruby, CoffeeScript, Octave, R, PSPP, etc), software development tools, libraries for programs, system administration tools, forensic and security tools, graphics/photography/image/sound/video tools, internet tools, office tools, science tools, CD/DVD/ISO tools, emulators, and accessories.

The total disk usage of the system is approximately 21 GB when a distribution is installed in a hard disk drive, and the number of total software packages installed in Step 4 above is approximately 3,000. The freeware installed in Step 5 above consists primarily of programming languages and development environment software, including Eclipse 4.3.2, Octave 3.8.2, MatlabFns, RStudio, redis-2.8.19, CloudCompare 2.6.1, OpenCV 2.4.10, gmic-1.5.8.2, ffmpeg-2.5.2, juman-7.0, dlib-18.12, XML-XML2JSON 0.06, jQuery UI 1.11.0, linq.js 2.2.0.2, Plot Digitizer.

List of DBLab distributions

The DBLab distributions are based on the following desktop Linux OS. They are variations of the Ubuntu OS.

The Lubuntu project no longer maintains lubuntu.net. The official Web site is https://lubuntu.me/.

System Settings

The system settings (Step 7 above) include the following items. The default settings for the system language and keyboard assume the US. Please change the system setting by yourself. The current settings are described below.

Tips

boot procedure using DVD-R/DVD-RW

  1. download an ISO image file from the Download Web page
  2. burn the ISO image file on a DVD-R/DVD-RW to make a live DVD.
  3. insert the live DVD into your PC, restart your PC, and configure BIOS to boot from DVD drive.
  4. boot from the live DVD.

You can install to a hard disk.

boot procedure using USB key

  1. download an ISO image file from the Download Web page
  2. Make a USB key from the ISO image file using a USB key generation tool, such as "Rufus", "balenaEtcher", or "UNetbootin". LinuxLive USB Creator (LiLi) has not been updated since 2015, so one of the above tools is used instead.
  3. insert the live USB key into your PC, restart your PC, and configure BIOS to boot from the USB key.
  4. boot from the USB Key.

There are three methods by which to run the system.

  1. (method 1) Run the ISO image file or the USB key as a virtual machine on another host OS.
  2. (method 2) Boot from a USB key after configuring the BIOS to allow booting from the USB key (described above).
  3. (method 3) Install the system from a USB key to a hard disk, and boot from the hard disk.

There is difference between the above three methods. Method 1 has the lowest disk and graphics performance, and the guest OS is isolated from the host OS by the virtual machine. Method 2 is faster than method 1, and it requires a BIOS (or UEFI) setting change. Method 3 is the fastest and can handle large data files, and it requires an installation to a hard disk. In methods 1 and 2, files are kept after a reboot only when a virtual disk image or a persistence area on the USB key is prepared. The size of the persistence area determines the size of the database that can be stored.

Software List

The following software list is not exhaustive. Some of the software in the list is not installed in some of the DBLab distributions in order to save disk space.
