Download your config

From TunnelFleet, download the user’s .conf file to your Ubuntu machine.

Issue	Fix
`wg-quick: command not found`	Install the `wireguard` package
Permission errors	Config must be readable by root; mode `600` is recommended
No handshake	Check UDP 51820 outbound and server firewall
Resolving DNS fails	Confirm the `[Interface]` `DNS` line in the profile
