+Support for both app and packages was dropped for Android `5` and `6` on [2020-01-01](https://www.reddit.com/r/termux/comments/dnzdbs/end_of_android56_support_on_20200101/) at `v0.83`, however it was re-added just for the app *without any support for package updates* on [2022-05-24](https://github.com/termux/termux-app/pull/2740) via the [GitHub](#github) sources. Check [here](https://github.com/termux/termux-app/wiki/Termux-on-android-5-or-6) for the details.
 
 The APK files of different sources are signed with different signature keys. The `Termux` app and all its plugins use the same [`sharedUserId`](https://developer.android.com/guide/topics/manifest/manifest-element) `com.termux` and so all their APKs installed on a device must have been signed with the same signature key to work together and so they must all be installed from the same source. Do not attempt to mix them together, i.e do not try to install an app or plugin from `F-Droid` and another one from a different source like `GitHub`. Android Package Manager will also normally not allow installation of APKs with different signatures and you will get errors on installation like `App not installed`, `Failed to install due to an unknown error`, `INSTALL_FAILED_UPDATE_INCOMPATIBLE`, `INSTALL_FAILED_SHARED_USER_INCOMPATIBLE`, `signatures do not match previously installed version`, etc. This restriction can be bypassed with root or with custom roms.
