Public bug reported:
Longtime user, first time reporter (apologies if I make any etiquette
mistakes in this bug report).
when I attempt to install python3.7-dev on a stock 19.10 install, I get
the following:
py@om:~$ sudo apt-get install python3.7-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
python3.7-dev : Depends: python3.7 (= 3.7.5~rc1-2) but 3.7.5-2~19.10 is to be
installed
Depends: libpython3.7-dev (= 3.7.5~rc1-2) but it is not going
to be installed
Depends: libpython3.7 (= 3.7.5~rc1-2) but 3.7.5-2~19.10 is to
be installed
E: Unable to correct problems, you have held broken packages.
It appears that the current version of libpython3.7 released in this
distro is 3.7.5-2~19.10.
If I attempt to downgrade python3.7 to the version that has an
associated -dev package, the results seem... undesirable:
py@om:~$ sudo apt-get install --allow-downgrades python3.7-minimal=3.7.5~rc1-2
python3.7=3.7.5~rc1-2 libpython3.7-stdlib=3.7.5~rc1-2
libpython3.7-minimal=3.7.5~rc1-2

Do you want to continue? [Y/n] ^C
Please package a version of python3.7-dev that is compatible with the
rest of the operating system. I would love to use those headers :)
Thank you!
