I am using Ubuntu 18.04.4 LTS, and I am attempting to install libgpgme-dev. Here is the command and output.

$ sudo apt install libgpgme-dev

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:
 libgpgme-dev : Depends: libgpgme11 (= 1.10.0-1ubuntu1) but 1.10.0-1ubuntu2 is to be installed
E: Unable to correct problems, you have held broken packages.

I have the dependency libgpgme11 installed, but the version is 1.10.0-1ubuntu2, whereas my desired package requires 1.10.0-1ubuntu1.

$ dpkg --list | grep libgpgme11
ii  libgpgme11:amd64  1.10.0-1ubuntu2  amd64  GPGME - GnuPG Made Easy (library)

How can I install libgpgme-dev given my current state?

I searched the installed reverse dependencies of libgpgme11, and this is what I find.

$ apt-cache rdepends --installed libgpgme11
libgpgme11
Reverse Depends:
  libgpgmepp6
  fwupd
  seahorse
  libvolume-key1
  libgpgmepp6
  fwupd
  libgmime-3.0-0

Here are the outputs of apt-cache policy for the relevant packages.

$ apt-cache policy libgpgme11 libgpgme-dev

    can you add apt-cache policy libgpgme11 libgpgme-dev to your question please? – nobody Aug 11 '21 at 13:14
  • @nobody - i added the output. thanks for the suggestion – jkr Aug 11 '21 at 13:23

    sudo apt install --reinstall libgpgme11=1.10.0-1ubuntu1 Then try again. – nobody Aug 11 '21 at 13:25

    Did you remember to update the local catalog (sudo apt update) before attempting the install? If not (or not sure) please do so now and re-run apt-cache policy libgpgme11 libgpgme-dev – steeldriver Aug 11 '21 at 13:46
  • @steeldriver - yes I ran sudo apt update before all of this. Would installing libgpgme11=1.10.0-1ubuntu1 potentially cause problems? This is a shared computer. – jkr Aug 11 '21 at 15:18
  • If you have concerns you cam make a simulation first. sudo apt -s install --reinstall libgpgme11=1.10.0-1ubuntu1 – nobody Aug 11 '21 at 15:24
  • thanks @nobody - from that simulation, it seems like only libgpgme11 will be modified. if you want to submit this as an answer, i'm happy to accept it – jkr Aug 11 '21 at 15:42

    @jakub it kind of looks like you had the bionic-updates repository in your sources.list when you installed libgpgme11 but now have only bionic ... – steeldriver Aug 11 '21 at 15:44
  • @steeldriver - interesting... it could be. would you suggest adding back bionic-updates? – jkr Aug 11 '21 at 15:47
  • @jakub I would expect that if you add back bionic-updates and re-run sudo apt update then you will see version 1.10.0-1ubuntu2 of both packages – steeldriver Aug 11 '21 at 15:51

  • Wow, nice catch @steeldriver. Indeed bionic-updates was not included, and now when I try to install my desired packages (in simulation), I don't get the hold errors. Thank you very much. – jkr Aug 11 '21 at 18:06
