I need to install this specific Python version, to prepare a developer environment, because I'm maintaining a system with multiple libraries based on python 3.6.9. I recently installed Ubuntu 22.04 on my laptop, but I had no success trying to install this python version.
I tried to install with apt-get after adding the deadsnake repository, but this python version is not available.
I tried installing from source by compiling, but it did not work. Running sudo make altinstall exited with this error:
Segmentation fault (core dumped)
make: *** [Makefile:1112: altinstall] Erro 139
I have faced the same problems and could make it work by adding some additional flags when running ./configure
Here are my steps:
Step 1 – Prerequsities
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev \
libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev \
libgdbm-dev libnss3-dev libedit-dev libc6-dev
Step 2 – Download Python 3.6
wget https://www.python.org/ftp/python/3.6.15/Python-3.6.15.tgz
tar -xzf Python-3.6.15.tgz
Step 3 – Compile Python Source
cd Python-3.6.15
./configure --enable-optimizations -with-lto --with-pydebug
make -j 8 # adjust for number of your CPU cores
sudo make altinstall
Step 4 – Check the Python Version
python3.6 -V
