Ubuntu 18.04. I have a pip (2.7) installation that fails for not finding "Python.h". I tried this:

$ sudo apt install python-dev --fix-missing

and got this for output:

Reading package lists... Done
Building dependency tree... 50%

The following package was automatically installed and is no longer required:
  python-all
Use 'sudo apt autoremove' to remove it.
The following additional packages will be installed:
  libpython-dev libpython2.7 libpython2.7-dev python2.7-dev
The following NEW packages will be installed:
  libpython-dev libpython2.7 libpython2.7-dev python-dev python2.7-dev

After this operation, 45.5 MB of additional disk space will be used.

What do I need to do to get python-dev installed?

    Did you remember to sudo apt update first? it looks like your package catalog refers to the 18.04.1 point release – steeldriver Nov 01 '19 at 17:05

sudo sed -i s,//us.archive,//archive,g  /etc/apt/sources.list

or use 

software-properties-gtk

enter image description here

and choose download from main server.

after that

sudo apt update && sudo apt install python-dev

Both ways change the apt sources to main server.

    Their problem is they likely didn't apt update first - and thus are working out of outdated data about the repos. – Thomas Ward Nov 01 '19 at 17:17
  • Well, that's pretty awesome, a word I'm very careful about using. Thanks! (I did run apt update first.) – RadlyEel Nov 01 '19 at 17:46
