Anyone know the issue? I cannot install libjpeg62-turbo because:

root@support:/opt/librenms# apt install libjpeg62-turbo
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package libjpeg62-turbo is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘libjpeg62-turbo’ has no installation candidate

Help would be appreciated!

i think it’s still using your old php version, what does php -v say?

the turbo thing i don’t think will make much difference but it looks like it can resolved as follows: https://askubuntu.com/questions/921555/how-to-install-libjpeg62-turbo-on-ubuntu-16-04-2-lts-xenial/921822

The error I see is:

Missing PHP extensions. Please install and enable them on your LibreNMS server.

murrant · 8 February 2019 20:43

That is an odd error. What version of bash are you using?

Do you get the same result with /bin/bash daily.sh ?

Did you try to install the missing extension?

Did you disable your old php entirely? e.g https://www.rosehosting.com/blog/how-to-install-php-7-2-on-ubuntu-16-04/

Bottomline is that php7.2-gd will not install due to libjpeg62-turbo.

Do I need libjpeg62-turbo?
How do I remove it?
Maybe upgrade to 7.3?

I have spend many hours filling my LibreNMS and now it is unavailable

Chas · 9 February 2019 16:51

Yeh I don’t know if you need it but i’m guessing so,

How did you install 7.2 ? it’s possible your packages might be messed up , check what repo’s your using,

you could try, but i think you have already

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.2-gd

if all fails i would uninstall 7.2 completely, and try re-installing with a good php repo for ubuntu16

Serverion · 9 February 2019 17:57

Yup, I have tried them all unfortunately… I think upgrading to 18.x will be an option or otherwise install CentOS 7.x and suppose all problems are gone…

Chas · 9 February 2019 18:05

yeh probably worth a try. it seems on 18.04 you will use universe repo: https://docs.librenms.org/Installation/Installation-Ubuntu-1804-Nginx/

Some others experienced some issues when upgrading just for info Upgrade ubuntu 16.04 to 18.04 - DB Issue

Serverion · 9 February 2019 19:02

I have finally fixed it …

I removed all PHP versions and installed the old libjpeg62-turbo using dpkg… PHP7.2 installed fine and my Libre is back up. (Debian -- Package Download Selection -- libjpeg62-turbo_2.1.5-2+b2_amd64.deb)

Chas and Murrant, again thanks for the help again have a good night!
