[Bug 2072656] [NEW] Missing dependency on libsnappy1v5

[Simon Déziel]

Public bug reported:

On Noble, installing `ceph-common` result in one of the .so to be
missing a dependent .so:


```
$ lxc launch ubuntu-daily:24.04 c1
$ lxc shell c1
root at c1:~# apt-get update && apt-get install -Vy ceph-common
...
root at c1:~# dpkg -L ceph-common  | grep snap
/usr/lib/x86_64-linux-gnu/ceph/compressor/libceph_snappy.so.2.0.0
/usr/lib/x86_64-linux-gnu/ceph/compressor/libceph_snappy.so
/usr/lib/x86_64-linux-gnu/ceph/compressor/libceph_snappy.so.2
```

This `libceph_snappy.so.2.0.0` in turn depends on `libsnappy.so.1` but
it's not found:

```
root at c1:~# ldd /usr/lib/x86_64-linux-gnu/ceph/compressor/libceph_snappy.so.2.0.0
	linux-vdso.so.1 (0x00007ffd72b74000)
	libsnappy.so.1 => not found
	libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007643adce4000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007643adcb7000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007643adaa5000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007643ad9bc000)
	/lib64/ld-linux-x86-64.so.2 (0x00007643adf72000)
```

This `libsnappy.so.1` is normally provided by the `libsnappy1v5` package
and installing it manually fixes it:

```
root at c1:~# apt-get install -y libsnappy1v5
...
root at c1:~# ldd /usr/lib/x86_64-linux-gnu/ceph/compressor/libceph_snappy.so.2.0.0
	linux-vdso.so.1 (0x00007ffdb7b25000)
	libsnappy.so.1 => /lib/x86_64-linux-gnu/libsnappy.so.1 (0x00007537db3ed000)
	libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007537db170000)
	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007537db143000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007537daf31000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007537dae48000)
	/lib64/ld-linux-x86-64.so.2 (0x00007537db409000)
```

For some reason, `ceph-common` had a dependency on `libsnappy1v5` in
Jammy but it was lost afterward, causing this issue.
