There are two ways to download Ubuntu
Method 1: Direct download
# Check the system to be installed
proot-distro list
# Download and install Ubuntu
proot-distro install ubuntu
Method 2: Install from a compressed package
If direct download is too slow, you can first download the image compressed package from GitHub, specific link: https://github.com/termux/proot-distro/releases/download/v4.18.0/ubuntu-noble-aarch64-pd-v4.18.0.tar.xz
Place the downloaded compressed package file into the phone's a/file directory, then move it to the $PREFIX/var/lib/proot-distro/dlcache directory, and then execute proot-distro install ubuntu. Specific commands:
# Move the compressed package
mv ~/file/ubuntu-noble-aarch64-pd-v4.18.0.tar.xz $PREFIX/var/lib/proot-distro/dlcache
# Execute the download command
proot-distro install ubuntu
After installation is complete, log in to Ubuntu
proot-distro login ubuntu
