upgrade from OMV4 to OMV5, error with mbstring

roeboat · Jun 30th 2021

I'm attempting to upgrade from OMV4 to OMV5. I began with dliedert's script, which fails with:

PHP Fatal error: Uncaught Error: Call to undefined function mb_strtolower() in /usr/share/php/openmediavault/autoloader.inc:28

The failure is at line 8454 in the attached log dated 2021-06-30-075916.

After that, I find my OMV server has buster installed, so dliedert's script won't continue. Apache is running, so the rest of the server seems okay. After doing some reading and searching, I tried uninstalling and re-installing mb-7.3string, but that didn't change anything. After the above failure using dliedert's script, I could only execute 'omv-update' and it continually fails with the same error. Thanks for any help.

Hi there,

I have the same error and I followed this update script. I cannot execute any apt-get command without a failure. For example:

I read somewhere that this shall be avoided. Can I fix this somehow?

yes, would have come to the same conclusion.

Quote from Silenzium

I don't know where they come from

usually other applications have been installed directly without placing them in a docker container, screwing OMV up.

1.backup
2. uninstall all other applications but watch out for "dependent packages" uninstall to not include openmediavault

Silenzium, mi-hol

Apologies for not updating this, but I came to much the same conclusion. With a mix of php installs, I could no longer tease apart what I needed to get OMV5 functional. I gave up and then did a clean install. Good luck with it.

Silenzium · Jul 26th 2021

Thanks for your responses.

2. uninstall all other applications but watch out for "dependent packages" uninstall to not include openmediavault

OK, but where should I start?

If that does not work and a clean installation is unavoidable, I have two questions:

1. Is OMV 6 stable enough to use it in production and to avoid the future upgrade from 5 to 6?

2. Are there any recommendations to bring as much as possible from my OMV 4 configuration to OMV 5 or 6?

Edit:

A third way could be to restore the images from omvbackup and to try the update again. But I've no idea which type of backup I did choose. I guess this look like rsync?

I booted into a live distribution and restored my omv backup with rsync folder by folder. I used this guide:

https://averagelinuxuser.com/b…-linux-system-with-rsync/

Now I'll try to upgrade again.
