Operating Systems

Barcode Xpress for Linux runs on 64-bit Linux operating systems:

• Ubuntu 20.04
• Ubuntu 18.04
• CentOS 8
• CentOS 7
• Debian 9
• Debian 10

On CentOS 8 operating system, Barcode Xpress License Manager may not work since some cryptographic protocols are disabled by default. In this case, to install a license on the local computer, required mode can be enabled with the following command (run it as a root):

update-crypto-policies --set LEGACY

After installing the license, default mode can be enabled with the command:

update-crypto-policies --set DEFAULT

See command description:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/security_hardening/using-the-system-wide-cryptographic-policies_security-hardening

Barcode Xpress for Linux will also run on other Linux distributions, as long as those fully satisfy the requirements listed in this section.

We do not recommend using Snap to install Barcode Xpress because necessary external dependencies don't exist in the Snap container.
