Comment 18 for bug 1912389

Performing the verification for Hirsute:

First, reproducing the bug with the version currently available:

# apt policy snmpd
snmpd:
  Installed: 5.9+dfsg-3ubuntu1
  Candidate: 5.9+dfsg-3ubuntu1
  Version table:
 *** 5.9+dfsg-3ubuntu1 500
        500 http://archive.ubuntu.com/ubuntu hirsute/main amd64 Packages
        100 /var/lib/dpkg/status
# snmpd -DALL
...

Segmentation fault (core dumped)

Now, updating the package to the version available in -proposed and making sure that the bug is fixed:

# apt policy snmpd
snmpd:
  Installed: 5.9+dfsg-3ubuntu1.21.04.1
  Candidate: 5.9+dfsg-3ubuntu1.21.04.1
  Version table:

        100 /var/lib/dpkg/status
