问题分析 #

从日志能定位三个核心问题：

1. 命令参数不兼容：报错明确提示Unknown action 'c'，当前版本的ProtonVPN-CLI不支持短选项c，必须使用完整的connect命令。
2. 旧配置残留：初始报错显示尝试调用/usr/local/bin/protonvpn，说明存在旧service配置残留，或daemon-reload未完全生效。
3. 运行上下文错误：默认systemd服务以root用户运行，而ProtonVPN的登录凭证存储在用户目录下，root身份无法读取用户aleph的VPN配置。

修复方案 #

1. 更新systemd服务配置 #

替换/etc/systemd/system/protonvpn.service内容为：

[Unit]
Description=ProtonVPN-CLI auto-connect
Wants=network-online.target
After=network-online.target
Requires=network.target

[Service]
Type=oneshot
ExecStart=/usr/bin/protonvpn connect -f
Environment=PVPN_WAIT=300
Environment=PVPN_DEBUG=1
User=aleph
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

• 改Type=forking为Type=oneshot：适配protonvpn connect -f的一次性执行特性，配合RemainAfterExit=yes让systemd识别服务为活跃状态。
• 替换c为connect：匹配当前CLI的命令格式。
• 添加User=aleph：让服务以指定用户身份运行，确保能读取用户的VPN凭证。
• 添加Requires=network.target：强制依赖网络服务，避免提前启动导致连接失败。

2. 清理残留并重新加载配置 #

执行以下命令：

# 停止当前服务
sudo systemctl stop protonvpn
# 检查是否存在其他同名服务文件
ls /etc/systemd/system/protonvpn* /usr/lib/systemd/system/protonvpn*
# 若有旧文件则删除，然后重新加载配置
sudo systemctl daemon-reload
# 重新启用并启动服务
sudo systemctl enable --now protonvpn

3. 验证连接状态 #

执行命令确认服务和VPN状态：

sudo systemctl status protonvpn
protonvpn status
