The deb post-install script script will now copy the key file over if
apt-key
fails. This was released a while back, but we forgot to close the issue. Thank you for the suggestion Mike!

On Ubuntu 20.04.1 LTS 64-bit i get the followin error while installing:
dpkg: error processing package screen-desktop (--configure):
installed screen-desktop package post-installation script subprocess returned error exit status 1
I did try to uninstall completely and install from scratch downloading the .deb file.

Mike Dalessio: Thanks again for the help!
Federico Biccheddu: Let us know if you're still having issues after following the steps Mike gave here. We'll also be working to incorporate a fix into the script so we no longer run into this issue, although this workaround should help you get up and running asap.

J Sherwani (Pop Team): unfortunately cannot install 3.0.2 even trying Mike Dalessio's solution.
Can I help in some way?

I had a similar problem with earlier versions, and the issue was with unrelated gpg keys. Similar symptoms, and fix, here: https://askubuntu.com/questions/1246031/gpg-invalid-key-resource-url-following-docker-official-guide

Hi! Thank you for your quick response.
v2.1.4 exhibits the same error message for me.
I went back and tried to install older versions of screen that previously installed cleanly -- back to v1.2.10 and v2.1.0 -- and they are also now exhibiting this error. My conclusion is that something has changed on my machine recently, but I don't know what that would be without digging into the configuration scripts.
I'd be happy to try to debug if you can help me by pointing at the config/installation scripts.

Mike Dalessio: Here are the scripts we use:
Deb:
https://packagecloud.io/install/repositories/screen/screen/script.deb.sh
RPM:
https://packagecloud.io/install/repositories/screen/screen/script.rpm.sh
Let us know if you find the issue.

J Sherwani (Pop Team): Thanks, will look today.

I also just released an update (v2.1.4) built with a slightly different build environment. Could you test to see if that works?
J Sherwani (Pop Team)
Thanks for reporting this!
I just installed Mint 20 in a VM (tried with each of Cinnamon, Mate and Xfce, via https://www.linuxmint.com/download.php) and
sudo apt install screen-desktop_2.1.3_amd64.deb
worked for me. Are you able to reproduce this in a fresh install?M
Mike Dalessio
J Sherwani (Pop Team): OK, I dug into this a bit this morning. I believe the problem occurs during the
postinst
script, which I think explains why the package is "Status: install ok half-configured" (see https://www.debian.org/doc/debian-policy/ch-maintainerscripts.html#details-of-configuration).Specifically, the cron job that's installed returns a non-zero exit code for me on my machine. More specifically, the function
install_key
is returning 1
because apt-key add
is returning 1

OK - looks like I had a bad key configured from another project, and that was causing
apt-key add
to exit with code 1
. See https://askubuntu.com/questions/1246031/gpg-invalid-key-resource-url-following-docker-official-guide for similar problem and solution.I
think
this is why current best practice is to avoid using apt-key add
to add your project's key, and instead (from the apt-key man page):> a keyring should be placed directly in the /etc/apt/trusted.gpg.d/ directory with a descriptive name and either "gpg" or "asc" as file extension.
Hope this helps?

Mike Dalessio: Wow, this is very helpful — thank you so much!
@mustafa-hashmi: let's get this into the install script asap!
