I did some more testing on libcec

On a fresh install of raspbian -
sudo apt install libcec-dev
Fails with this error
libcec-dev : Depends: libcec4 (= 4.0.1+dfsg1-1+rpi1) but 4.0.2.3~stretch
is to be installed

I don't know why it wants to install a different version of the
dependency, but doing the following instead works:
sudo apt install libcec4=4.0.1+dfsg1-1+rpi1
sudo apt install libcec-dev

There may be two versions of the dependency available in the repository,
but that does not explain why it wants to install the wrong version of
the dependency.

It seems something is set up wrongly for it to fail this way. You should
be able to depend on an out of date version without it breaking.

Further to this - after installing the old version of libcec4 and the
libcec-dev as above, I ran an update and it happily upgraded the libcec4
to the newer version without complaining that libcec4-dev was dependent
on the older version.

Hi Peter,

The library has changed names during the lifetime of stretch.
There was a period that it was libcec4-dev.

A ticket was opened about this, and I did some investigation
and actually the libcec-dev package is the newest package

I'm on

# lsb_release
No LSB modules are available.
root@raspberrypi:~# lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description: Raspbian GNU/Linux 9.6 (stretch)
Release: 9.6
Codename: stretch

with these repo's enabled (the default AFAICT)

# apt policy
Package files:
100 /var/lib/dpkg/status
release a=now
500 http://mirrordirector.raspbian.org/raspbian stretch/rpi armhf Packages

release o=Raspbian,a=stable,n=stretch,l=Raspbian,c=main,b=armhf
origin mirrordirector.raspbian.org

<lightbulb>.....

Looking again at the pull request that was submitted about this
https://github.com/MythTV/ansible/pull/2

That user had 2 archive repositories enabled, which are actually
debian repos, not raspbian repos.

So I would try uninstalling libcec4, disable the 2 archive repos,
and re-run


Regards
Stuart
