5 months ago The error message you're seeing indicates that the repository for the deadsnakes PPA does not have a release file for Ubuntu 23.04 (Lunar Lobster). This is why the apt command is failing to add it.
The deadsnakes PPA may not support Ubuntu 23.04 yet, or the repository URL might not be set up correctly for this version. Here are a few steps you can take to resolve the issue:
-
Check the
deadsnakesPPA page: Sometimes, the repository might not be available for the latest Ubuntu release immediately. Check the deadsnakes PPA page to see if there's an update or any information regarding support for Ubuntu 23.04. -
Use an older Ubuntu version's PPA: If the
deadsnakesPPA isn't available for Ubuntu 23.04, you can try using the PPA for an older version of Ubuntu that is supported by thedeadsnakesPPA. For example, you can try using the repository for Ubuntu 22.04 (Jammy Jellyfish).
To do this, manually add the repository entry for jammy:
sudo add-apt-repository -y ppa:deadsnakes/ppa
sudo sed -i 's/lunar/jammy/g' /etc/apt/sources.list.d/deadsnakes-ubuntu-ppa-lunar.list
sudo apt updateThis manually edits the sources list to point to the jammy repository instead of lunar.
-
Check for alternative repositories: Sometimes there are other PPAs or repositories that can be used to install the desired Python versions. For instance, Ubuntu's official repositories might already have the Python version you need.
-
Build from source: If the desired Python version is not available through any repository, you might consider building Python from source. This can be more time-consuming but ensures you can get the specific version you need.
Here’s how to build Python from source:
sudo apt update
sudo apt install -y build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev curl libbz2-dev
# Download the source code for the desired Python version
curl -O https://www.python.org/ftp/python/3.11.4/Python-3.11.4.tgz
tar -xf Python-3.11.4.tgz
cd Python-3.11.4
# Configure and install
./configure --enable-optimizations
make -j $(nproc)
sudo make altinstallThis will install Python 3.11.4 as python3.11 without interfering with the system's default Python version.
By trying one of these solutions, you should be able to resolve the issue and install the desired Python version on your Ubuntu 23.04 system.
For further questions or need help use the discord forum instead.
Thank you!
