我在 Windows 10 上安装 Ubuntu 时遇到了一些错误。我刚刚进入“Ubuntu 世界”，真的需要一些帮助。
执行 apt 更新后，我收到以下错误。
"6 packages can be upgraded. Run 'apt list --upgradable' to see them.
N: Download is performed unsandboxed as root as file '/var/cache/apt-build/repository/dists/apt-build/InRelease' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)"
After doing the apt upgrade I am receiving this message.
