Steps
- Read current release notes for distribution and architecture requirements; they change as .NET and UI frameworks advance.
- On Debian/Ubuntu use `sudo apt install ./v2rayN-linux-64.deb`; on Fedora/RHEL use `sudo dnf install ./v2rayN-linux-rhel-x64.rpm`, adjusting the real filename.
- For a ZIP, extract it, run `chmod +x v2rayN`, then `./v2rayN` as a normal user.
- Check desktop session, system-proxy integration and tray support. Configure TUN privileges separately according to official documentation.
Why this matters
The package manager tracks installed files and dependencies; portable builds are useful for testing or systems without a matching package.
How to verify
The app runs as a normal user, persists settings, changes system proxy correctly and can be queried or removed by the package manager.
Things to watch
Do not assume an old distribution remains supported. Upgrade the OS rather than downloading outdated binaries from an unknown source.
