sudo apt install python-pip
, and you’re unable to do so. Most likely, it happens due to either an outdated or misconfigured repositories list.
Our summary table about this issue could look something like this:
| Error Message | Possible Cause | Solution |
|---|---|---|
| E: Package python-pip has no installation candidate | Outdated/misconfigured repositories list | Update your sources.list file; Install python-pip via get-pip.py script. |
There may be few solutions around it:
– The first is updating your
sources.list
file since it might have been outdated hence not being able to find relevant packages. For instance, you can try using the following commands for updating package list:
sudo apt-get update
sudo apt-get upgrade
– If the error persists, you can use get-pip.py, a Python script maintained by the official Python Packaging Authority which allows installing pip in Python environment and helpful when the native package manager fails.
Remember, always ensure that the software sources lists are updated regularly to avoid such errors in the future.When a user tries to install Python PIP on their Linux system and encounters the error “
E: Package 'python-pip' has no installation candidate
“, it can be confusing and frustrating. Let’s delve into what this really means.
The message essentially means that the desired package named ‘
python-pip
‘, seems to not exist in the current list of available packages for APT (Advanced Packaging Tool) to install from. Now, the question arises, “Why would the software be missing from the online repositories?”
$ sudo apt-get install python-pip Reading package lists... Done Building dependency tree Reading state information... Done Package python-pip is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'python-pip' has no installation candidate
Here are the possibilities:
– The required software might have been deprecated due to a new version. As older versions sometimes contain security issues, they’re often phased out once newer, more secure versions come in. In our case,
python-pip
has been largely replaced by
python3-pip
as Python2 has reached end-of-life status[^1^].
– Software host servers periodically update their list of packages — this process, however, might unwittingly omit some software.
– It’s also possible that the software was intentionally removed if found to contain a significant number of bugs or security issues.
Whatever is the root cause behind this, let’s focus on the solution. Here is how you can solve this issue:
– Update your repository. This can be achieved with the command:
sudo apt-get update
. This will refresh your local list of available software with the updated list from the server.
– Often resolving the dependencies before installing the software helps.
sudo apt-get build-dep packagename
.
– Replace
python-pip
with
python3-pip
, because the former has been ditched for the latter in recent Ubuntu distributions. Hence the commands would be
sudo apt-get install python3-pip
.
Still facing the same problem? No worries! Try manually installing pip using the Python Installer “get-pip.py”. Here are the steps[^2^]:
1. First, download get-pip.py. Use the following command:
wget https://bootstrap.pypa.io/get-pip.py
2. Then run the following command to install pip for Python:
sudo python3 get-pip.py
And Voila! Pip should now be installed successfully. You can verify its installation via
pip --version
or
pip3 --version
.
Always know that even in coding, “There are many ways to skin a cat” holds meaning. When one method doesn’t work, there’s always an alternative path to reach your goal.
Happy coding!

Sure, when you try to install Python Pip on your Linux and you see the error `E: Package ‘python-pip’ has no installation candidate`, it means that there was no candidate package found for pip in your package list. This issue is quite common in different versions of Linux.
First let’s understand what this message actually means – When you request to install a package using a package manager, such as apt-get or yum, your OS looks for the suitable package in its database (retrieved from the repositories). The term “installation candidate” comes into the picture when there is a newer version of the software available than the one already installed. Your system will consider the new version as an “installation candidate”.
If your system returns the error `Package ‘python-pip’ has no installation candidate`, this could mean:
– The required repository that contains the package isn’t added
– You missed updating the package lists
So what are some solutions?
$ sudo apt update $ sudo apt install python-pip
The above commands signify a good practice before installing any package in Linux. First, update the package list using `sudo apt update` and then attempt to install the desired package. If you’re still seeing the same error message, it indicates that the proper repository is missing in the source list.
Some cases where ‘python-pip’ doesn’t have an installation candidate can be fixed by enabling the universe repository in Ubuntu which contains free and open-source software not maintained officially by Canonical. To do this :
$ sudo add-apt-repository universe $ sudo apt-get update
After updating the repositories, try installing the package again with `sudo apt install python-pip`. (source)
In the event that these measures aren’t enough, it’s possible PIP isn’t included in the default repo. In this case, the best alternative would be to download and install PIP from its official webpage.
One must also keep in mind that ‘Python-pip’ reflects the package name in older distributions of Ubuntu. Post Ubuntu 20.04, ‘pip’ corresponds to Python 2 and ‘pip3’ to Python 3. To successfully install Pip for Python 3, use: `sudo apt install python3-pip`.
Understanding the functionalities of package managers and reflecting on error messages like ‘no installation candidate’ can provide comprehensive insights about software management in Linux. It’s necessary to constantly stay updated with changes in package details specifically when dealing with frequent updates and multiple versions of the same software. Having a detailed understanding of these potential errors ensures efficient problem-solving and better consistency in the functioning of your system.You might encounter the problem “
E: package python-pip has no installation candidate
“, which can be frustrating as a software developer. This issue arises commonly when Linux users are trying to install the Python pip (Package installer for Python) package on their systems. In such scenarios, there could be a range of reasons why this error occurs. By understanding these causes, we can better tackle and resolve them with precision and speed.
* **Obsolete Repository**
Missing or outdated repositories are common triggers for this specific error. When you operate an older version of Ubuntu, for instance, certain packages may not be accessible since they have been removed from the main repository. Alternatively, if updates are required for the local package index, failure to do so will produce similar issues.
sudo apt-get upgrade sudo apt-get update
A prudent action would be to carry out routine checks for any system upgrades or updates. These can ensure that the repositories are current and the package information is accurate, thereby minimizing errors.
* **Incorrect Package Name**
Occasionally, the mistake could stem from using the incorrect name in specifying the package. For example, typing in “python-pip” instead of the correct “python3-pip”. It’s advised to double check the appropriate naming conventions as each operating system requires its specific syntax.
sudo apt-get install python3-pip
* **Unsupported Python Version**
An incompatible Python version can also lead to this error. Should you be on a Python version that doesn’t support pip, or may be deprecated; it will cause problems. It is essential to migrate to versions that support pip. Remember, pip was included by default from Python3.4. So, always know your Python version.
python --version
It’s crucial to frequently assess compatibility factors between the different elements of your tech-stack to maintain seamless operational continuity.
Once you delve into these potential causes, it becomes manageable to identify where the source of the problem lies. Notably, debugging will encompass a mixture of research, comprehension of technical functionalities, and testing.
