Description

When executing the «Let’s install dependencies code», an error message related to the python-dev occurs: the package is not found. This results in no dependencies being installed at all.

System: Ubuntu 22.04 LTS fresh install (oh, the joys of forgetting to update a non-LTS version of Ubuntu in time. ).

Screenshots

When executing the «Let’s install dependencies code», the following error occurs:

Package python-dev 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 However the following packages replace it: python2-dev:i386 python2:i386 python2-dev python2 python-dev-is-python3 E: Package 'python-dev' has no installation candidate 

Potential solutions
I’ve seen a screenshot of a recent WSL install where it could not find this package either, but replaced it by python-dev-is-python2 . (Which made me wonder if python-dev-is-python3 would not make more sense?)

I took another approach to test if I could just omit python-dev (knowing that python3-dev package is installed), which seems to work.

I haven’t thoroughly tested, but I could continue setup up until and including the jupyter part without problems. Will update this issue if I encounter any problems later on.

How can I install python-dev off apt-get?

I have tried this and this and this and this None of those install python-dev, I got my amd64 system, 14.04 up and running, as I try to install wagtail, a django cms, I get the error:

 pysass.c:4:20: fatal error: Python.h: No such file or directory #include ^ compilation terminated. error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 ---------------------------------------- Cleaning up. Command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/ libsass/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace ('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-ojWg1O-record/install- record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/libsass Storing debug log for failure in /home/payload/.pip/pip.log 

How can I fix this and install the package? It’s because of the missing Python.h c header which is included in the python-dev package. When I tried the above links, it says: apt-get install python-dev

Package python-dev 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 However the following packages replace it: python E: Package 'python-dev' has no installation candidate 

Package python2.7-dev 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 'python2.7-dev' has no installation candidate 

I have researched on the debian archives and found a package for python 2.7.8-1 but that couldn’t be installed. Tried this on launchpad too but doesn’t work.
