Solved Debian 9/3CXV16 upgrade to Deb 10/V18 fails

[Dominique_CH]

Launched the upgrade process normally from the management console. As after an hour, the system wasn't back up, logged in via SSH.
- OS is still Debian 9
- 3CX services removed

So, where can I find the logs showing the reasons for this failure?.
- Checked /var/log/, but none of the logs present around the upgrade time shows any type of error
- /var/log/apt contains 2 logs, history.log and term.log, but no error either
- /var/log/postgresql shows that postgress upgrade aborted for some unknown reason (see attachment)

Any help is welcome

I guess, I'll have to perform a clean install of v16 'til I can go onsite to install Debian 10 manually. But is this possible with a partially upgraded Debian 9 system ???

Hi,

You can find more information on upgrade failure reasons here https://www.3cx.com/blog/docs/linux-upgrade-troubleshooting-tips/

Just for information in case anybody is interested or facing similar issues: I made a clean install using the 3CX-provided iso and that also fails. For details, check https://www.3cx.com/community/threa...ails-on-unmet-dependencies.84857/#post-397635.

So, my advice would be to upgrade w/ great care and do not blindly believe the "93% success rate"

Hello,

The issue with the upgrades has been resolved a few hours ago and the OS upgrade option has been restored in the Management Console. We have also resolved the issue with the ISO in some cases showing a dependency error, as well as check that installations occur normally on our supported Hosting Platforms and RPi.

If there are any comments that you need share with us, I would ask that they are all gathered in this post:
