# Python version upgrade
|
||
|
|
|
||
|
|
#### Notes
|
||
|
|
Upgrade described in this documentation file can be useful when using a system such as Ubuntu18, which default Python is no longer supported (in this case Python 3.6). The recommended action is to use a newer system instead of upgrading Python.

## Building and installing Python for Linux
|
||
|
|
|
||
|
|
Download Python from Python releases page and extract it:
|
||
|
|
https://www.python.org/downloads/release
|
||
|
|
```bash
|
||
|
|
curl -O https://www.python.org/ftp/python/3.8.13/Python-3.8.13.tgz
|
||
|
|
tar -xf Python-3.8.13.tgz
|
||
|
|
```
|
||
|
|
|
||
|
|
Prepare the build with the `.configure` tool, ensuring that `pip` will be installed:
|
||
|
|
```bash
|
||
|
|
cd Python-3.8.13
|
||
|
|
./configure --with-ensurepip=install
|
||
|
|
```
|
||
|
|
|
||
|
|
Build Python with number of jobs suitable for your machine:
|
||
|
|
```bash
|
||
|
|
make -j 8
|
||
|
|
```
|
||
|
|
|
||
|
|
Install your new Python version, making sure not to overwrite system Python by using `altinstall` target:
|
||
|
|
```bash
|
||
|
|
sudo make altinstall
|
||
|
|
```
|
||
|
|
|
||
|
|
Verify your installation:
|
||
|
|
```bash
|
||
|
|
python3.8 --version
|
||
|
|
> Python 3.8.13
|
||
|
|
```
