UFS Explorer in APT repositories for the Debian Linux family
The Debian Linux family (including Ubuntu, Mint and other distributions) offers centralized software package management by means of APT repositories, available from multiple customizable sources. To ensure seamless integration of UFS Explorer into the standard APT package management infrastructure, we provide a dedicated "third-party" repository that can be used to maintain the software on Debian-based systems.
Once enabled, the repository allows you to install or remove UFS Explorer using standard APT commands, just like any other software package within the distribution. Meanwhile, APT handles dependency resolution and verifies package compatibility prior to installation. This mechanism also makes it possible to update the software through regular package management tools.
Repository selection
UFS Explorer is available through two APT repositories: "deb-curr" and "deb-legacy". The "deb-curr" repository offers UFS Explorer software built with recent versions of development tools, while "deb-legacy" provides broader compatibility with older systems. Note that some software editions, such as UFS Explorer Professional Recovery or UFS Explorer Technician, are not available in the legacy repository.
To choose the appropriate repository, we recommend checking the version of the "libc6" package on your system:
$ apt info libc6 Package: libc6 Version: 2.41-12+deb13u1 Priority: optional
If this library has version 2.27 or higher, we recommend using the "deb-curr" repository. For versions "2.3" to "2.26" (released on or after 2006), only "deb-legacy" is available. Older versions of "libc6" are not supported at all.
Quick registration of the UFS Explorer repository
The "deb-curr" APT repository can be quickly registered using the following command:
# wget http://sdl.ltd/debc.sh | bash # apt update
The "legacy" repository ("deb-legacy") on an older system can be registered with:
# wget http://sdl.ltd/debl.sh | bash # apt-get update
Software installation and removal
Once the source is registered, run the "sudo apt update" command ("sudo apt-get update" on older systems) to refresh the list of available packages.
If no errors are reported, you can install UFS Explorer products using the "apt" (or "apt-get") command, for example:
# apt install ufsxsci
The command above installs UFS Explorer Standard Recovery; the software can be removed later using the "apt purge" command. The list of package code names for different UFS Explorer products is provided below.
List of UFS Explorer package code names
The table below contains the list of binary UFS Explorer software packages. Please note that some software editions, such as UFS Explorer Professional Recovery or UFS Explorer Technician, are only available in the "deb-curr" repository and only for the "amd64" architecture.

Registration of the UFS Explorer repository explained
The repository installation scripts above perform the following operations, which you can also execute manually:
# wget https://www.sysdevlabs.com/download/deb/pgp-key.public -O /usr/share/keyrings/sdl-uk-repo.gpg
- Downloads and installs the GPG certificate of the repository.
# wget https://www.sysdevlabs.com/download/deb/sdl-deb-curr.sources -O /etc/apt/sources.list.d/sdl-deb-curr.sources
- Downloads and installs the APT source.
To undo these changes, you can remove these files:
# rm /usr/share/keyrings/sdl-uk-repo.gpg # rm /etc/apt/sources.list.d/sdl-deb-curr.sources
For the "legacy" repository, similar commands are used:
# wget http://www.sysdevlabs.com/download/deb/pgp-key.public -O /usr/share/keyrings/sdl-uk-repo.gpg # apt-key add /usr/share/keyrings/sdl-uk-repo.gpg
- Downloads and registers the public key certificate.
# wget http://www.sysdevlabs.com/download/deb/sdl-deb-legacy.list -O /etc/apt/sources.list.d/sdl-deb-legacy.list
- Installs the "source".
Once the selected repository is registered, UFS Explorer can be installed, updated or removed like any other APT package.
