Hey,
as I was running out of diskspace on the systemdisk, I deleted everything in /var/cache - I now know that this was not a good idea...
I manually created /var/cache/openmediavault/ and /var/cache/openmediavault/archives - Afterwards apt-get was working again.
However, the web-gui is not working. I get the following message in the browser:
Error #0:
OMV\Exception: Failed to open file
(filename=/var/cache/openmediavault/cache.omv\controlpanel\login_js.json,
mode=w+). in /usr/share/php/openmediavault/json/file.inc:71
Stack trace:
#0 /usr/share/php/openmediavault/controlpanel/controlpanelabstract.inc(183): OMV\Json\File->open('w+')
#1 /var/www/openmediavault/index.php(46): OMV\ControlPanel\ControlPanelAbstract->render()
#2 {main}
Makes sense as cache.omv does not exist. However, even after creating this manually, the web-gui is not working. Also, the tools under omv-firstaid did not solve anything. I also tried the release-upgrade to version 4 which was available. No luck either.
How can I reinstall the web-gui? (And everything else that was in /var/cache/openmediavault/ that I might have lost...)
Or what folders do I need to setup in /var/cache/ ?
Thanks for the help!
