方式二：压缩包安装

直接下载太慢的话，可以在github上先把镜像压缩包下载下来，具体链接：https://github.com/termux/proot-distro/releases/download/v4.18.0/ubuntu-noble-aarch64-pd-v4.18.0.tar.xz

将下载的压缩包文件放到手机的a/file目录，再移动到$PREFIX/var/lib/proot-distro/dlcache目录下，再执行proot-distro install ubuntu。具体命令：

1

#移动压缩包
mv ~/file/ubuntu-noble-aarch64-pd-v4.18.0.tar.xz $PREFIX/var/lib/proot-distro/dlcache
#执行下载命令
proot-distro install ubuntu

安装完成后，登录ubuntu
