Error while installing Jitsi

Question

I am not very knowledgeable when it comes to Ubuntu. I wanted to install Jitsi because I didn't know there's a web application. While installing I came across an error which I tried to resolve but didn't managed to. And because I was told it was accessible via browser I ignored it. Now I want to customize my terminal but when trying to install new packages there is the following error:

The given hostname does not exist in the config
dpkg: error processing package jitsi-meet-prosody (--configure):

dpkg: dependency problems prevent configuration of jitsi-meet:

Answer 1

Try doing a complete uninstall using:

apt-get purge jigasi jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet-turnserver jitsi-meet-web jicofo jitsi-videobridge2

Then, so a reinstall, using the instructions here:

https://jitsi.org/downloads/ubuntu-debian-installations-instructions/

Specifically:

sudo apt-get -y install jitsi-meet

from a terminal window.

IMPORTANT: when prompted to input your FQDN for DNS configuration, using something like meet.jit.si, not localhost.

Here's the URL of the page where I saw this:

https://github.com/jitsi/jitsi-meet/issues/5053/

Test your installation by loading your browser (e.g., Chrome or Safari) and joining an existing jitsi meeting, or go to meet.jit.si to create a new one.

Answer 2

Try:

apt autoremove

Then:

apt-get --purge remove jitsi-meet jitsi-meet-web jitsi-meet-prosody jitsi-meet-web-config jicofo jitsi-videobridge

This will remove the packages of jitsi, that you do not want to use.

Answer 3

If you tried change prosody config, it is not removed automatically.

1. Delete package about jitsi

sudo apt purge jigasi jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet- turnserver jitsi-meet-web jicofo jitsi-videobridge2

2. Delete dependency package.

apt autoremove

2. Delete below two directories.

/etc/prosody and /etc/jitsi

3. reinstall jitsi package

apt-get -y install jitsi-meet

Answer 4

This is a tentative answer intended to be informative and might lead to a solution. This answer is in the context of my attempts to install the Desktop GUI for Jitsi which seems to have its own problems:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package jitsi

notably, this error is for jitsi (client) rather than jitsi-meet (server).

Although even that error isn't fully established.

My speculation is that perhaps the above potential problem has a direct, or even indirect, bearing on the stated problem with installing (or removing) jitsi-meet with apt as above.

The linked answer is:

Jitsi's documentation appears to be (currently?) inaccurate. Today the Packages file downloaded from http://download.jitsi.org/stable/Packages in the end provides only theses packages (in multiple versions and architectures):

$ grep-dctrl -F Package -s Package --regex '.*' < Packages | uniq
Package: jibri
Package: jicofo
Package: jigasi
Package: jitsi-archive-keyring
Package: jitsi-meet-prosody
Package: jitsi-meet-tokens
Package: jitsi-meet-turnserver
Package: jitsi-meet-web-config
Package: jitsi-meet-web
Package: jitsi-meet
Package: jitsi-upload-integrations
Package: jitsi-videobridge2
Package: jitsi-videobridge

There's no jitsi package.

However the jitsi package does exist in the nightly builds (reached by replacing the word stable with unstable in the sources.list file).

To be thorough, in April 2020 there was a snapshot made by archive.org of the stable repository, which did include the jitsi version 2.10.5550-1 package, dated from 2017. So I can only conclude that it was removed for some unknown reason from the stable repository.

This former missing 2.10 stable package is still available through this other Jitsi web page and the linked URL:

https://desktop.jitsi.org/Main/Download.html

https://github.com/jitsi/jitsi/releases/download/Jitsi-2.10/jitsi_2.10.5550-1_amd64.deb

Or else you can add the jitsi nightly builds to get the 2.11.x versions:

sudo sh -c "echo 'deb https://download.jitsi.org unstable/' > /etc/apt/sources.list.d/jitsi-unstable.list"

(as the package jitsi-archive-keyring is the same in the unstable repository and would also install /etc/apt/sources.list.d/jitsi-stable.list with the stable version url, it makes sense to use a different file to avoid it being overwritten)

There appears to be some inconsistency between the different methods available.

which is provided in the event that, as pointed out, the original answer gets deleted or otherwise lost in the shuffle.
