Hi Jim,
Ubuntu 16.04 LTS support has ended already in 2021 so we accordingly
stop supporting this platform. At the moment, we only have packages for
Ubuntu 20.04 TLS. We have updated documentation to reflect this change.
Could you please try this with Ubuntu 20.04 and let us know if this
works?
Regards,
Jaormir

  Hi
 We manage the .co.zw 2LD registry for Zimbabwe and are interested in
 migrating
 to use the FRED registry management system.
 We first installed Ubuntu 16.04 LTS (Xenial Xerus) from scratch, with
 basic
 utilities + sshd server package only, and then followed the
 instructions for
 installation of FRED binaries at:
 
https://fred.nic.cz/documentation/html/AdminManual/Installation/BinsUbuntu.…
 The first problem we found was with this command:
 # sudo apt-key adv --keyserver hkp://keys.gnupg.net:80 --recv-keys
 0x1C0200016A9AC5C6
 The above keyserver has closed down so the site could not be found.
 We then
 used 
keyserver.ubuntu.com instead, ie:
 # sudo apt-key adv --keyserver 
keyserver.ubuntu.com --recv-keys
 0x1C0200016A9AC5C6
 That was successful, with response:
 gpg: key 6A9AC5C6: public key "CZ.NIC Release Automatic Signing Key
 <archive-sign-key(a)nic.cz>" imported
 We then continued with the instructions until the following command:
 # sudo apt-get update
 The response was:
 GPG error: 
http://archive.nic.cz/ubuntu xenial Release: The following
 signatures couldn't be verified because the public key is not
 available:
 NO_PUBKEY E6DD3CAC7844804C
 W: The repository 'http://archive.nic.cz/ubuntu xenial Release' is
 not signed.
 We therefore requested the missing key (not in original notes):
 # apt-key adv --keyserver 
keyserver.ubuntu.com --recv-keys
 E6DD3CAC7844804C
 That was successful, with response:
 gpg: requesting key 7844804C from hkp server 
keyserver.ubuntu.com
 gpg: key C11F5931: public key "CZ.NIC Release Automatic Signing Key
 <archive-sign-key(a)nic.cz>" imported
 We continued with the instructions until we came to installing the
 FRED package
 itself:
 # sudo apt-get --assume-yes install fred
 The response was:
 The following packages have unmet dependencies:
   fred : Depends: fred-pyfred but it is not going to be installed
          Depends: fred-rsifd but it is not going to be installed
          Depends: nagios-pyfred-genzone-plugin but it is not going to
 be
 installed
          Depends: pyfred-filemanager but it is not going to be
 installed
          Depends: pyfred-genzone but it is not going to be installed
          Depends: python-pyfred but it is not going to be installed
 E: Unable to correct problems, you have held broken packages.
 We then tried with aptitude instead, ie:
 # sudo aptitude install fred
 The failed response was:
 The following packages have unmet dependencies:
   python-pyfred : Depends: python-pygresql (>= 1:5.0) but it is not
 going to be
 installed.
   bind9-host : Depends: libbind9-140 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)
 but
 1:9.10.3.dfsg.P4-8ubuntu1.19 is to be installed.
                Depends: libdns162 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)
 but

                Depends: libisc160 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)

                Depends: libisccfg140 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)

                Depends: liblwres141 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)

   dnsutils : Depends: libbind9-140 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)
 but
 1:9.10.3.dfsg.P4-8ubuntu1.19 is to be installed.

              Depends: libisccfg140 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)
 but

              Depends: liblwres141 (= 1:9.10.3.dfsg.P4-8ubuntu1.16)
 but
 1:9.10.3.dfsg.P4-8ubuntu1.19 is to be installed.
   fred-pyfred : Depends: python-pygresql (>= 1:5.0) but it is not
 going to be
 installed.
 However aptitude could not fix the problem.
 We removed the bind9-host and dnsutils packages, then ran "sudo apt-
 get update"
 and "sudo apt-get upgrade", then reinstalled them and tried the
 aptitude
 install again. This time it just reported:
 The following packages have unmet dependencies:
   python-pyfred : Depends: python-pygresql (>= 1:5.0) but it is not
 going to be
 installed.
   fred-pyfred : Depends: python-pygresql (>= 1:5.0) but it is not
 going to be
 installed.
 The following actions will resolve these dependencies:
       Keep the following packages at their current version:
 1)     fred [Not Installed]
 2)     fred-pyfred [Not Installed]
 3)     fred-rsifd [Not Installed]
 4)     nagios-pyfred-genzone-plugin [Not Installed]
 5)     pyfred-filemanager [Not Installed]
 6)     pyfred-genzone [Not Installed]
 7)     python-pyfred [Not Installed]
       Leave the following dependencies unresolved:
 8)     pyfred-filemanager recommends fred-pyfred
 9)     pyfred-genzone recommends fred-pyfred
 Accept this solution? [Y/n/q/?]
 No packages will be installed, upgraded, or removed.
 0 packages upgraded, 0 newly installed, 0 to remove and 0 not
 upgraded.
 Need to get 0 B of archives. After unpacking 0 B will be used.
 Do you have any suggestions as to how to proceed from here?
