OS: Ubuntu 20.04.2 LTS
Version: AMP Release "Ganymede" v2.1.0.2, built 03/02/2021 00:32

Problem Description:
When trying to change the port of an instance, you get this message (https://i.imgur.com/RdpowSw.png). When looking in the instance logs you can find this (https://pastebin.com/snS7Mq0t).

Steps to reproduce:
Well I actually don't know how to reproduce the problem, since we have a fresh installation of AMP.

Actions taken to resolve so far: None, since I don't actually have any idea how to fix this issue.

I can also confirm this issue is happening with v2.1.0.2 (upgrade from 2.1) on Ubuntu 20.04.2 LTS - this is a fresh install of Ubuntu. I am using Docker in my case.

I use AMP without Docker because I was thinking that Docker might be the problem.

Same problem here. Ubuntu 20.04 server, no docker. Have this problem with 3 minecraft instances. Also, managing instances only work when opening in a new tab and having to login again.

Problems started after upgrade to 2.1.0.2

Please fix this asap. Seems to be a huge gap in release bug testing.

I can't currently reproduce this, but I will look into it.

If you want to, I can give you temp access to my server to look into the problem.

Are you using controller/target setups, or standalone mode?

PlazzmiK posted this 05 February 2021

Standalone, single server. Multiple instances on same machine.

Managed to track the issue down, ironically fixing the issue that caused port updates not to get synced between targets caused this. Nightly will have a fix from tonight onwards (if you're brave), otherwise it'll be in an update next week.

Where can I upgrade to nightly, and turn it back to stable in a week? Currently having a server that's offline due to a port issue. Or can I change it manualy somehow?

PlazzmiK posted this 06 February 2021

Updated my instance to nightly using the following command:

ampinstmgr switch INSTANCENAME Nightly

Still hasn't fixed the problem.

Did you upgrade the instances after switching? You can upgrade all the instances using:

ampinstmgr --nocache upgradeall

That'll upgrade them all. Though, my guess is that you'll possibly only need to upgrade the ADS as it may be compatible with existing stable instances:

ampinstmgr --nocache ADS01

Obviously, if you haven't already, you'll need to switch the ADS to Nightly:

ampinstmgr switch ADS01 Nightly

That fixed it! Thanks.

Would you mind sharing the steps to switch back to the stable release later on?

AbhorrentJoel posted this 06 February 2021

It should be possible to just wait for the next stable release and just hop back onto that release cycle:

ampinstmgr switch INSTANCENAME MainLine True

And obviously update that instance that you switched back to stable release. Or all of the instances, if you changed all back to stable.

I am not sure if something bad could happen as a result to switching back, but as long as the stable release is newer than the Nightly then the features/changes should already be incorporated. Though, the risk is not quite zero.

Looks like this has been fixed now. I've given it a quick test and chaning the ports for instances now works without throwing an error.
