Change Python version from 3.5.3 to 3.5.2

Question

I need to downgrade my python3.5 from 3.5.3 to 3.5.2 because of some asyncio features. I installed python3.5 using next commands:

sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.5

But there was no options like selecting needed version. Is it possible to downgrade to 3.5.2?

Answer 1

The first thing you should make sure is whether 3.5.2 version is available in your repository. You can check that by running apt-cache policy python3.5. Check all the available candidate versions.

If 3.5.2 is available then install it using apt-get install python3.5=3.5.2

If not then add the respective ppa which hosts the 3.5.2 version and apt-get update and install it using the above command.

WARNING: Downgrading the package from external repositories might break the system. It's always recommended to use the distribution provided repository which are well tested before releasing.Use with caution!

Answer 2

Here is the solution. But also it will delete all modules you have.

sudo apt-get install libssl-dev openssl
wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz
tar xzvf Python-3.5.2.tgz
cd Python-3.5.2
./configure
make
sudo make install
