当我尝试安装 nRF 命令行工具时。
下载安装文件后nrf-command-line-tools_10.17.0_amd64.deb，我将权限更改为可执行
-rwxrwxrwx 1 r0n9 r0n9 45888940 Aug 3 20:36 nrf-command-line-tools_10.17.0_amd64.deb*
但是当我./nrf-command-line-tools_10.17.0_amd64.deb在终端中运行时，出现错误：
./nrf-command-line-tools_10.17.0_amd64.deb: line 1: syntax error near unexpected token `newline'
./nrf-command-line-tools_10.17.0_amd64.deb: line 1: `!<arch>'
尝试使用 dpkg 安装该包
sudo dpkg -i ./nrf-command-line-tools_10.17.0_amd64.deb，我收到以下错误
