There is no official Termux APT repository that permanently hosts old versions of packages. Termux removes old package versions from its repositories as soon as new versions are released, primarily due to storage and maintenance reasons. This means you cannot simply install a specific older version of a package unless you have previously saved its .deb file locallyreddit.com+1.

However, there are a few workarounds if you need an old package version:

1. Manual Build from Source: You can use the Termux package build system (termux-packages) to check out a specific commit that contains the version you want, then build and install it manuallyreddit.com+1.
2. Legacy Repositories: For very old Termux versions (such as those for Android 5), there are legacy repositories or archives (e.g., termux-repositories-legacy) that might contain old packages, but these are not updated and are only relevant for specific, outdated Android versionsreddit.com+1.
3. Local Cache: If you previously installed the package, check your local APT cache at /data/data/com.termux/files/usr/var/cache/apt/archives/ for the .deb file.

If you need help with a specific package or version, let me know which one you’re looking for!
