Industrial OS 3.2.3 on IOT2050Adv: No multiarch support?

Hello faschmidt,

The problem you're experiencing is due to conflicting libraries in your current system and the software you're trying to install. When you install the 32-bit software, the apt package manager wants to ensure that the dependencies are met. Since there are conflicting versions of these libraries, apt wants to remove them. That's why it looks like apt is trying to clean up your system.

The issue with the libcurl4:armhf package in particular is likely due to the fact that it depends on libssl1.1:armhf, but libssl1.1:arm64 is already installed and these two are not co-installable.

One workaround could be to install the 32-bit version of the software into a chroot environment. This would isolate any software and its dependencies from the rest of your system, preventing any conflicts with IndOS’ existing packages.

Here's a basic set of instructions on how to perform a minimal workaround:

• Add the armhf architecture to your package manager:

• Download the 32-bit version of libcurl4 and its dependencies without installing them:

• Manually extract and install the downloaded package to a directory:

• Add this directory to the library path when you need to run the 32-bit software:

export LD_LIBRARY_PATH=/usr/armhf/lib/arm-linux-gnueabihf/:$LD_LIBRARY_PATH

./your-32-bit-software

This workaround assumes that your software is a standalone executable that doesn't rely on any system services or additional libraries that might also need to be present in 32-bit form. If your software relies on more system services or libraries, this approach may be more complex and difficult to manage than simply setting up a chroot environment or using containerised applications with Docker.
