Just now i downloaded the Ubuntu 18.04 in my android mobile using termux and then i realise this taken so much space so i wana to delete the data that i had downloade Ubuntu 18.04 , but i dono how to delete , could you tell me how to delete it, i tried so many ways but its not freeing up space, I deleted using rm biut still it is not freeing up space.

1. Use rm -rf ubuntuXX-fs (XX is version number) / rm -rf Ubuntu

2. Download Activity Manager from Play Store and find the Google file manager. Launch the activity that launches the file manager, go-to termux for and delete all the things that have Ubuntu in name!

3. Search for official termux backup tutorial, reinstall termux and restore with the tutorial

I hope that helps
