@girish Ok I'm dumb... I had quotation marks around the LD_PRELOAD variable I added in this file: /etc/default/collectd

Seems to work now. This can be closed, sorry!

@necrevistonnezr Don't upgrade yet, I have a blog post that I will publish later today on how to update. It's a bit different than 16 to 18. That main difference is that the mysql server has to be upgraded as well.

@girish I successfully migrated my Cloudron from one server to another. I followed your directions and updated Cloudron to v 6.0.0 before making my final backup of the old server.

Thank you.

@gml said in SSL error after upgrading to 5.6.0 on ubuntu 16:

That seemed to solve it, even if a server reboot did not solve it. I also got a mail, that this was also visible from other mail-servers (not just from my mail client), as I use DANE for certificate pinning.
Thx girish!

I had the same issue. And the same fix. A reboot didn't work, a service restart did the trick. Thanks!

I am not an expert on AWS, but aren't AWS instances only CPU+RAM ? I thought the disk does not resize. This is for EC2 instances though. Are you using lightsail by any chance?
