[libc++1 dependency] (Version: 19.2.0)

Start by comparing the generated dependency metadata for stellar-core 19.1.0 and 19.2.0, then check the available libc++ packages on Debian 10. The issue is done when stellar-core 19.2.0 can be installed or upgraded on Debian 10 without unmet libc++ dependencies.

Issue Description

We are going to upgrade stellar-core from v19.1.0 to v19.2.0. We found that the libc++ dependencies have been changed from libc++1-8 to libc++1-10:

root@stellar-1:~$ apt info stellar-core=19.1.0-943.e801fd93b.bionic
Package: stellar-core
Version: 19.1.0-943.e801fd93b.bionic
Priority: optional
Section: web
Maintainer: Package Maintainer <packages@stellar.org>
Installed-Size: 9209 kB
Depends: libsqlite3-0 (>= 3.11.0), stellar-core-utils, **libc++1-8**, **libc++abi1-8**, libc6 (>= 2.25), libgcc1 (>= 1:3.0), libpq5

root@stellar-1:~$ apt info stellar-core=19.2.0-966.d18d54aa3.bionic
Package: stellar-core
Version: 19.2.0-966.d18d54aa3.bionic
Priority: optional
Section: web
Maintainer: Package Maintainer <packages@stellar.org>
Installed-Size: 9020 kB
Depends: libsqlite3-0 (>= 3.11.0), stellar-core-utils, **libc++1-10**, **libc++abi1-10**, libc6 (>= 2.25), libgcc1 (>= 1:3.0), libpq5

However, there is no libc++1-10 available on debian (but libc++1-11 as shown below).

root@stellar-1:~$ cat /etc/debian_version 
10.12
root@stellar-1:~$ uname -a
Linux stellar-1 4.19.0-20-cloud-amd64 stellar/stellar-core#1 SMP Debian 4.19.235-1 (2022-03-17) x86_64 GNU/Linux
root@stellar-1:~$ apt list libc++1\* -a
Listing... Done
libc++1-11/oldstable 1:11.0.1-2~deb10u1 amd64
libc++1-11/buster-backports,buster-backports 1:11.0.1-2~bpo10+1 amd64

libc++1-7/oldstable 1:7.0.1-8+deb10u2 amd64

libc++1-8/buster-backports,buster-backports,now 1:8.0.1-3~bpo10+1 amd64 [installed,automatic]

Steps to Reproduce

root@stellar-1:~$ apt install stellar-core

Reading state information...
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:
 stellar-core : Depends: libc++1-10 but it is not installable
                Depends: libc++abi1-10 but it is not installable

Expected Result

It is expected that stellar-core can be installed on debian 10 with dependencies on available libc++ packages on the linux distribution

Actual Result

stellar-core 19.2.0 cannot be installed/upgraded
