python-boto: libssl1.1 dependency problems

[tomtom]

Latest python-boto package for Ubuntu Bionic (18.04) seems to have a dependency problem because of libssl1.1

Hi tomtom,

Thanks for reporting this and making Ubuntu better. I was able to install python-boto 2.44.0-1ubuntu2 successfully with apt. Is this still a problem if you use apt to install from the bionic archive?

Thanks,
Corey

Yes, unfortunately it is still a problem.
There was an update to libssl available today (libssl1.1:amd64) but also after this upgrade I get the same error:

Same problem for me in all my debian 9.6 servers.

[red shaphiro (redshaphiro)]

Solved with:

sudo dpkg -i python-boto_2.44.0-1.1_all.deb
sudo dpkg -i python-boto3_2.44.0-1.1_all.deb

apt-get update
apt-get upgrade

But is it a safe solution?

I'm not sure where libssl1.1 version 1.1.1a-2+ubuntu18.04.1+deb.sury.org+1 is coming from.

Where are you getting libssl1.1 from? What does 'apt policy libssl1.1' show?

Here are the current versios in bionic+ Ubuntu archives:

$ rmadison libssl1.1

My bad, it was installed via the ondrej ppa. I should have noticed that the current versions of libssl is 1.1.0g and not 1.1.1a. I'm sorry for that.

$ apt policy libssl1.1

After downgrading all the packages installed via the ondrej/php installing python-boto was installed successfully.

Ok no problem, and thank you for responding back with details.
