I'm trying to install common-lisp-jupyter on Ubuntu 21.10, but Ubuntu won’t install one of the required libraries, namely zeromq.
When I tried to install zeromq using the libczmq-dev package, apt-get reported that there are two unmet dependencies, but apt-get also says that both the missing (?) packages are installed and up to date.
More specifically, when I try this:
sudo apt-get install libczmq-dev
I get this:
The following packages have unmet dependencies:
libsodium-dev : Depends: libsodium23 (= 1.0.18-1build1) but 1.0.18-1+ubuntu16.04.1+deb.sury.org+1 is to be installed
libxml2-dev : Depends: libxml2 (= 2.9.12+dfsg-4ubuntu0.2) but 2.9.13+dfsg-0+ubuntu20.04.1+deb.sury.org+1 is to be installed
But libsodium23 and libxml2 are both installed and up to date. I tried to call apt-get using the -f option and to install libczmq-dev using aptitude, but nothing worked. The output from aptitude says that the package "is not installable," but gives no clues as to why.
Even more baffling is that when I try:
aptitude install libsodium23
It returns
libsodium23 is already installed at the requested version (1.0.18-1+ubuntu16.04.1+deb.sury.org+1).
Doesn't this conflict with the output from apt-get?
The system is running on a Dell desktop machine. It was recently upgraded from 20.04 to 21.10 and everything else seems to be working OK.
Well, any help is appreciated.
UPDATE
apt update produces the following output:

6 packages can be upgraded. Run 'apt list --upgradable' to see them.
The upgradable packages are related to Thunderbird, so I think they’re not relevant to the libczmq installation.
