I tried to update Zammad from 5.4.1 to version 6.0. Unfortunately, the “zammad” package cannot be installed because it has been held. Guess it’s because Redis is missing.
I also tried to update Ubuntu 16.04 to 18.04, this failed because the “zammad” package was not updated…
Has anyone had the same problem?
Hi @touro8211,
according to New Major Release: Zammad 6.0!, redis is a mandatory dependency now. You need to install it, otherwise it’s not possible to use Zammad 6.0.
Thanks for the answer
What command can I use to install Redis?
I have tried this:
But it doesn’t work:
Unverified + untested: Install Redis on Linux | Redis
Otherwise you might need to use your favorite search engine with e.g. ubuntu 16.04 redis or any other fitting search terms 
Now, I have redis installed. But i cant update zammad. The same message: the “zammad” package cannot be installed because it has been held…
But I have redis installed…
The package on apt based system (at least for debian 10 and 11) would be redis-server.
The package expects redis which normally would also install the server variant. With the first package name you can overcome this.
After the installation a connection to redis locally should be possible. If not that and enable it manually.
Redis works!
And then by updating zammad:
Yeah so why has Zammad been hold back. Can’t tell or see the reason.
Frozen maybe?
I don’t know, zammad runs normally…
Backup zammad 5.4.1 – Install zammad on new system (debian 11 or Ubuntu 22.04) – Import Backup to Version 6.0
Is this solution workable?
Your package manger holds it back, at least that’s what the message tells you. I can’t tell the reasoning.
Technically yes.
See:
https://docs.zammad.org/en/latest/appendix/backup-and-restore/index.html
Make sure to set FULL_FS_DUMP to no for less pain during that operation.
(Backup configuration — Zammad System Documentation documentation)
Im guessing you ran the apt-get upgrade, or simillar, command? That will not work, since apt only upgrades the software if all dependencies are installed beforehand. You have to run apt-get install instead, that will install all dependencies and then the latest vesrion of zammad.
So remove redis that you installed manually, and then run the above.
I experience the same problem with updating ZAMMAD from 5.4.1 to 6.0.
Your advice to apt-get install ZAMMAD did not work for me but ended with the same message, that installing ZAMMAD is held because of the REDIS dependency.
I sincerly hope, that there will be a way to update, that does not involve deploying a backup.
So when you ran apt-get install zammad you still got that zammad had been held back because of dependencies? Can you show the output?
There are two other things you can try : apt-get --with-new-pkgs upgrade zammad, try this first, or a more dangerous route would be apt-get dist-upgrade
Thank you so much for your reply. I tried sudo apt-get update and sudo apt-get --with-new-pkgs upgrade zammad and got this Error:
user@zammad:~$ sudo apt-get --with-new-pkgs upgrade zammad

It is the same Error i got before, saying that zammad is depentent on redis.
Even using sudo apt-get dist-upgrade and afterwards sudo apt-get update and apt-get --with-new-pkgs upgrade zammad brought the same Error i had before.
Edit:
My Ubuntu Version is 16.04.7 LTS
My Zammad Version is 5.4.1-1681293771
Corrupted packages is the thing you may want to fix before trying anything else.
I was trying to correct the problem, but even dpkg --list | grep ^rc did not show any corrupted packages.
I’ve got stuck at the same point. Zammad 5.4.1 on Ubuntu 16.04LTS. I installed the redis-server, it is working, but the zammad package doesn’t find it.

Can the name “redis-server” the problem because zammad 6 (apt) looks for “redis”?
If you’re using Ubuntu, it should check for redis-server.
