Octopus Database "Padding is invalid and canot be removed"

I’m setting up octopus server as a container in EKS, and I have an MSSQL Express database setup in RDS. I created an empty database, octodb, in Express, and started up the container with the connectionstring. It blows up when trying to initialize the database. Here is the log output:

A little google came up with results regarding a migration and versions of Octopus being off, but this is a fresh, empty database. Any help would be appreciated.

Hi @eandrus,

Thank you for contacting Octopus Support.

Have you tried allowing Octopus to create the db during the install? If you did and it errored as well, did you get the same error message?

I look forward to hearing back from you.

Regards,
Donny

@donny.bell I actually just got done testing that. I told the container to use a completely different database in its connection string, one that didn’t exist yet. The log output was exactly the same, just with the new database name in it. I found that weird, given that one of the lines was

Database ‘octodb’ already exists on SQL Server at ‘address,1433’, no need to create it.

But with the new database name that I had not created. Any help would be appreciated. One of my team suspects a problem with password encryption, after some googling.

Hi @eandrus,

Thank you for getting back to me.

Could you tell me what version of Octopus Server you are using to create this installation?

Regards,
Donny

@donny.bell I just pulled the :latest octopusdeploy/octopusdeploy image

@donny.bell just an update to my last message, this should be the version I’m pulling:

https://hub.docker.com/layers/octopusdeploy/octopusdeploy/latest/images/sha256-c6f19d8e2d3026d46a8ff9cdb8ec8b4b6134ff4bdb85cf555a61f35eef4e8ce6?context=explore

Hi @eandrus,

Thank you for getting back to me.

If you haven’t already, double-check that C:\Octopus and C:\Programs Files\Octopus Deploy do not exist prior to installing.

Also, are you enabling encryption in RDS? If so, try turning that off to see if you get a different result.

Let me know what you think.

Regards,
Donny

Hi @eandrus,

I set up a test environment to see if I could replicate the issue.

The error you are receiving is a result of a new instance attempting to connect to an existing SQL db without the correct master key in a 2020.3+ installation. I recommend double-checking the parameters in your script to see if something is misconfigured.

If you would like to share a scrubbed version of your script, I would be happy to run it on my end as well to test. Just let me know.

Regards,
Donny

That’s how I’m deploying it.

@donny.bell I attempted to disable encryption on the database as you suggested, and got the following:

image

So not sure why Octopus can’t seem to set the master key.

Hi @eandrus,

I just wanted to update you.

I am still attempting to reproduce this error. I should have more information for you by tomorrow.

Thank you for your patience while we get this figured out.

Donny

Hi @eandrus,

Thank you for your patience. I was able to successfully reproduce your issue. I’m currently attempting to see if a fix that is already in the pipe-line for 2020.3.5 corrects this issue.

I will confirm with our engineering team in Australia to see if that is the case.

To get you unblocked, I would recommend trying 2020.2.18 instead, then wait until 2020.3.5 before upgrading:

octopusdeploy/octopusdeploy:2020.2.18

Let me know if 2020.2.18 works for you.

Regards,
Donny
