When using the command “$ make install” on the build folder of the desktop client folder as specified by this link: https://github.com/nextcloud/desktop/wiki/How-to-compile-the-desktop-client

I receive this error:

I am using ubuntu to install the client. Any help would be appreciated.

Why are you building from source? You can install Nextcloud from their repo or flatpak from flathub or as appimage or snap.

Thanks for the reply, I’m participating in a class project for my university where we’re trying to add a feature to the desktop client.
