For those who have this issue, I found the solution for Ubuntu 20.04, these are the steps:
1. Comment the 4 lines of
/etc/apt/source.list.d/zimbra.list
2. Remove these packets.
Code: Select all
sudo apt-get remove zimbra-openjdk zimbra-jetty-distribution zimbra-core-components zimbra-ldap-components
3.
Code: Select all
sudo apt clean all
sudo apt-get update
4. Uncomment the three first lines of
/etc/apt/source.list.d/zimbra.list, so, the deb-source will be the only one commented.
5.
6. Install these versions of the packets
Code: Select all
sudo apt-get install zimbra-openjdk=13.0.1-1zimbra8.8b1.20.04 zimbra-core-components=3.0.11-1zimbra8.8b1.20.04 zimbra-jetty-distribution=9.4.18.v20190429-2.u20 zimbra-ldap-components=2.0.5-1zimbra8.8b1.20.04
7.
Worked for me on three different servers.
