Hello @matejkriz,

I am experiencing this issue as well. Does this affect the security of the suite software in any significant capacities? I suppose it doesn't since the .AppImage file is still hosted on your website but I rather check before hooking up the device.

Thank you.

Also see this on Debian 11.

Thank you for your reports! This warning is nothing new and we do not use that deprecated API directly in our codebase, but one of our old dependency use it. We do not know about any abuse of this old API.

Here is some explanation of the context of the warning: https://nodesource.com/blog/understanding-the-buffer-deprecation-in-node-js-10/

@mroz22 The warning during app start comes from usage of bytebuffer dependency, can we replace it with something better maintained? https://github.com/trezor/trezor-suite/blob/develop/packages/protobuf/src/encode.ts/#L74

[matejkriz]

BTW it's not linux related, it can be seen on any platform running Suite from command line

[mroz22]

in general, bytebuffer should be replacable. We should do it.
