I'm trying to install Lazarus 4.2 on Astra Linux 1.7.
Unfortunately, there's no way to choose the Linux distribution or version (specifically, Astra 1.7). I have to use what's provided. So...
The "standard" Astra Linux 1.7 repositories include Lazarus, but it's a very old version, 2.0. I want to install the latest version.
I downloaded the official deb files. The first two (fpc-src and fpc-src) installed without errors. An error occurred on lazarus-project_4.2.0-0_amd64.deb:
The archive "lazarus-project_4.2.0-0_amd64.deb" uses an unknown compression method for control.tar.zst. Aborting.
Google searches revealed that the culprit is the outdated dpkg package manager, which I have at version 1.19.8, but should be at least 1.21.
Unfortunately, I'm new to Linux and can't solve this problem. Please help.
