installing ALPINE LINUX on any (old) android device using ssh-droid (tested: NEO G4 MINIX)

note: bit of unix-skills (vi e.g.) is needed (a very good investment for your future)

1. install ssh-droid thru playstore, or download/open its .apk file after googling
2. open ssh-droid
3. on another laptop/computer ssh into your android device
4. type mkdir alpine in your homefolder
5. download the following shellscript below by typing:

wget https://gist.githubusercontent.com/coderofsalvation/43d7d476dc5eeba98926b9437e52bb49/raw/27980cdb3d2dd2c49968549bc696f7e9ac3c17bc/install.sh && chmod 755 install.sh

5. update ARCH= to your architecture (surf to http://nl.alpinelinux.org/alpine to see the supported ones)
6. update INSTALL= to your chroot-folder location (absolute path)
7. run ./install.sh
8. profit!

now run this script (./alpine.sh e.g.) to teleport into your alpine distro!

#!/bin/sh
INSTALL='/data/data/berserker.android.apps.sshdroid/home/alpine'
mount -o bind /dev $INSTALL/dev # access all devices (usb etc) from linux
HOME=/root chroot $INSTALL bash

install.sh

mkdir -p $INSTALL/etc

mount -o remount,rw $(mount | grep '/system' | awk '{ print $1 }') /system

printf "${RED}initing DNS settings"
echo -e "nameserver $(getprop net.dns1)\nnameserver $(getprop net.dns2)" > /etc/resolv.conf
set +e; mkdir $INSTALL/etc; set -e
cp /etc/resolv.conf $INSTALL/etc/.

printf "${RED}Downloading Static installer apk...${NC}\n"
set -x
wget $MIRROR/$VER/main/$ARCH/apk-tools-static-$APKTOOLS.apk
tar -xzf apk-tools-static-*.apk
rm apk-tools-static-*.apk
rm .PKGINFO


printf "\n${RED}Installing Base Alpine...${NC}\n"
./sbin/apk.static -X $MIRROR/$VER/main -U --allow-untrusted --root $INSTALL --initdb add alpine-base
rm -r ./sbin/

printf "\n${RED}Adding Repos to chroot${NC}\n"
echo "$MIRROR/$VER/main" > $INSTALL/etc/apk/repositories
echo "$MIRROR/$VER/community" >> $INSTALL/etc/apk/repositories
echo "http://nl.alpinelinux.org/alpine/edge/testing/" >> $INSTALL/etc/apk/repositories

printf "\n\n${RED} Done! Logging into chroot..${NC}\n"
echo "in the future you can do this using: chroot $INSTALL bash"
chroot $INSTALL apk update

Is this for rooted devices only?

I can't remember, but I think this works for non-rooted as I used the ssh-droid app to SSH into the device (apps dont never run as root).
I've used it to install home assistant, which worked at some point after installing fakeroot (to fake homeassistant into thinking that i was root).

anyway to install it in external sdcard ? i have root if it matter

@abasgames maybe modify INSTALL=... to your desired location? (INSTALL=/sdcard e.g.)

@abasgames maybe modify INSTALL=... to your desired location? (INSTALL=/sdcard e.g.)

android exec limitations in external storage

@abasgames how about trying this on line 15:

mount -o remount,rw,exec /sdcard                    # maybe must be done with root?

Other then that I guess it's trial error

Running sh install.sh remounting /system as writable to write /etc/resolv.confmount: Permission denied

comes out how can i solve it? Need rooting?

My device is samsung SM-G150NK.

I don't have idea about this:

Read-only file system

I want to root my device. But how?

No apt, and apk.

And no sudo

@LEKPHET-KUNSUE It's possible that the script is broken / only works after rooting your specific device
