Package format doesn’t guarantee distribution compatibility
DEB and RPM are two different package formats. Check the system’s built-in installer or package manager before choosing. Even distributions that use the same format can differ in system libraries, dependencies, or target environment, which may prevent installation. For RPM packages with a target environment in the file name, follow the dependency results reported by the package installer. Don’t force an installation by ignoring missing dependencies.
The x64 packages are for common 64-bit desktop processors; file names may use amd64 or x86_64. arm64 packages may use aarch64. These terms describe processor architecture, not package format. Match the architecture first, then the distribution’s package management system, to avoid choosing a package that installs but can’t run.
Desktop environment and proxy settings
v2rayN is a graphical client that requires an available desktop session and compatible graphical runtime. A server with only a terminal isn’t suitable just because it can install the package. After installation, launch the app from the application menu, check that your configuration directory is writable, and import an existing subscription. Don’t run the entire client with elevated privileges long-term to work around directory permissions.
Desktop environments and apps may handle system proxy settings differently. After setting a system proxy in the client, check browsers, terminal programs, and other apps individually; they may not use the same proxy. If you need TUN, see the permissions and routing guidance in Advanced Configuration. Don’t troubleshoot the desktop proxy, environment variables, and TUN as if they were one setting.
