## Install
1. Get [Termux](https://f-droid.org/en/packages/com.termux/) from **F-Droid**.
2. Install Debian by running the following.
- Run `termux-setup-storage` to allow storage access, or else code-server won't be able to read from `/sdcard`.\
If you used the Andronix command then you may have to edit the `start-debian.sh` script to mount `/sdcard` just as simple as uncommenting the `command+=" -b /sdcard"` line.
> The following command was extracted from [Andronix](https://andronix.app/) you can also use [proot-distro](https://github.com/termux/proot-distro).
> After Debian is installed the `~ $` will change to `root@localhost`.
```bash
pkg update -y && pkg install wget curl proot tar -y && wget https://raw.githubusercontent.com/AndronixApp/AndronixOrigin/master/Installer/Debian/debian.sh -O debian.sh && chmod +x debian.sh && bash debian.sh
```
3. Run the following commands to setup Debian.
```bash
apt update
apt upgrade -y
apt-get install nano vim sudo curl wget git -y
```
4. Install [NVM](https://github.com/nvm-sh/nvm) by following the install guide in the README, just a curl/wget command.
5. Set up NVM for multi-user. After installing NVM it automatically adds the necessary commands for it to work, but it will only work if you are logged in as root;
- Copy the lines NVM asks you to run after running the install script.
- Run `nano /root/.bashrc` and comment out those lines by adding a `#` at the start.
- Run `nano /etc/profile` and paste those lines at the end and make sure to replace `$HOME` with `/root`
- Now run `exit` and start Debain again.
6. After following the instructions and setting up NVM you can now install the [required node version](https://coder.com/docs/code-server/latest/npm#nodejs-version) using `nvm install version_here`.
7. To install `code-server` run the following.
> To check the install process (Will not actually install code-server)
> If it all looks good, you can install code-server by running the second command
```bash
curl -fsSL https://code-server.dev/install.sh | sh -s -- --dry-run
```
```bash
curl -fsSL https://code-server.dev/install.sh | sh
```
8. You can now start code server by simply running `code-server`.
> Consider using a new user instead of root, read [here](https://www.howtogeek.com/124950/htg-explains-why-you-shouldnt-log-into-your-linux-system-as-root/) why using root is not recommended.\
> Learn how to add a user [here](#create-a-new-user).
## Upgrade
1. Remove all previous installs `rm -rf ~/.local/lib/code-server-*`
2. Run the install script again `curl -fsSL https://code-server.dev/install.sh | sh`
## Known Issues
### Git won't work in `/sdcard`
Issue : Using git in the `/sdcard` directory will fail during cloning/commit/staging/etc...\
Fix : None\
Potential Workaround :
1. Create a soft-link from the debian-fs to your folder in `/sdcard`
2. Use git from termux (preferred)
## Extra
### Create a new user
To create a new user follow these simple steps -
1. Create a new user by running `useradd username -m`.
2. Change the password by running `passwd username`.
3. Give your new user sudo access by runnning `visudo`, scroll down to `User privilege specification` and add the following line after root `username ALL=(ALL:ALL) ALL`.
4. Now edit the `/etc/passwd` file with your commadline editor of choice and at the end of the line that specifies your user change `/bin/sh` to `/bin/bash`.
5. Now switch users, by running `su - username`
- Remember the `-` betweeen `su` and username is required to execute `/etc/profile`,\
since `/etc/profile` may have some necessary things to be executed you should always add a `-`.
### Install Go
> From https://golang.org/doc/install
1. Go to https://golang.org/dl/ and copy the download link for `linux arm` and run the following.
```bash
wget download_link
```
2. Extract the downloaded archive. (This step will erase all previous GO installs, make sure to create a backup if you have previously installed GO)
```bash
rm -rf /usr/local/go && tar -C /usr/local -xzf archive_name
```
3. Run `nano /etc/profile` and add the following line `export PATH=$PATH:/usr/local/go/bin`.
4. Now run `exit` (depending on if you have switched users or not, you may have to run `exit` multiple times to get to normal termux shell) and start Debian again.
5. Check if your install was successful by running `go version`

### Install Python
2021-04-28 20:49:38 +00:00
> Run these commands as root
2021-04-28 20:49:38 +00:00

2021-04-28 20:49:38 +00:00
```bash
sudo apt-get update
sudo apt-get install make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm \
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
```
2. Install [pyenv](https://github.com/pyenv/pyenv/) from [pyenv-installer](https://github.com/pyenv/pyenv-installer) by running.
2021-06-23 18:26:59 +00:00
```bash
curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
```
2021-06-23 18:26:59 +00:00
3. Run `nano /etc/profile` and add the following
2021-04-28 20:49:38 +00:00
```bash
export PYENV_ROOT="/root/.pyenv"
export PATH="/root/.pyenv/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv virtualenv-init -)"
```

4. Exit start Debian again.
5. Run `pyenv versions` to list all installable versions.
6. Run `pyenv install version` to install the desired python version.
> The build process may take some time (an hour or 2 depending on your device).
7. Run `touch /root/.pyenv/version && echo "your_version_here" > /root/.pyenv/version`
8. (You may have to start Debian again) Run `python3 -V` to verify if PATH works or not.
> If `python3` doesn't work but pyenv says that the install was successful in step 6 then try running `$PYENV_ROOT/versions/your_version/bin/python3`.
