------------------------------------------------------------------

This is not an issue in install_prereq or Asterisk itself, but a package dependency problem in Ubuntu, as described on ASTERISK-25977:

Although I verified this, the issue isn't Asterisk related other than the Asterisk install_prereq script requires libsnmp-dev. In an install from CD, this package's default conflict resolution solution is to uninstall network-manager, openssh-server, git, perl and a whole bunch of other packages instead of upgrading them. The work-around is to do a 'apt-get update' followed by an 'apt-get upgrade' BEFORE running install_prereq. Once this is done, a subsequent install of libsnmp-dev completes successfully.
