Problem Connecting to Test

Hi I got new error this morning:

@howardkitto , I just wanted to let you know that we've seen the error and are scratching our heads. It's not something we've seen before. You seem to be having a lot of adventures; sorry about that. We'll get back to you after some analysis. (You happened to post this error right while I was in the middle of merging pull requests in some repos that sovrin depends on, and doing corresponding pypi publication. That should not have affected anything, but depending on how you installed your code, there's a tiny chance that something glitched. Anything interesting about your environment or about the steps that you took just before the error?)

@howardkitto This error comes if you do not have the file pool_transactions_sandbox in your ~/.sovrin. If that is the case , when you start the cli you should not see this printed Node registry loaded.. Can you confirm if you see this message and some other information about nodes, like this

Node registry loaded.

@dhh1128 Thanks for the swift response.

@lovesh
Here is the output when I start the cli:

$ sudo sovrin

Here is what's in ~/.sovrin

$ ls ~/.sovrin/

I did

$ sudo pip install -U --no-cache-dir sovrin

just in case, but that didn't fix it

[dhh1128]

@howardkitto I don't think you want to run sovrin via sudo. At least, I never have run it that way, and I'm guessing it might create some problems. Certainly it will change the meaning of ~/, which would explain this particular problem. If you have done this (sudo sovrin) once, it may create some state files that are confusing to the install; maybe @lovesh can tell you if you need to do anything special to clean up for experimenting without sudo.

[howardkitto]

Ok, laziness on my part ;)

I changed the permissions to this:

drwxr-xr-x 20 howardkitto staff 680 26 Oct 06:42 /Users/howardkitto/.sovrin
Maybe that's not correct because when I connect to test I still get

Error while running coroutine shell: IndexError('tuple index out of range',)

[dhh1128]

Those permissions look okay, but it's still going to be a problem to run sovrin with sudo, because sudo changes ~/ to mean "the home directory of the root user" instead of "the home directory of howardkitto". Did you try running sovrin without sudo now?

[lovesh]

@howardkitto Installing a package in your system wide packages is not a good idea as it can lead to conflicts among different package versions. We recommend using a virtual environment. The instructions for using a virtual environment are mentioned here. Please try it in a virtual environment, it should be good then.

[howardkitto]

@dhh1128 Yes it runs without sudo now but I still get the same error.

@lovesh I'll have a go at the virtual environment

[lovesh]

@howardkitto

Yes it runs without sudo now but I still get the same error.

This is weird. Can you try copying your ~/.sovrin/ to the root user's home, it might be that its looking at the home of the owner of sovrin which i guess in your case is root

[dhh1128]

@howardkitto did this get resolved?

[howardkitto]

No I'm afraid not

[lovesh]

@howardkitto The file pool_transactions_sandbox in your .sovrin is empty. I know you said you did sudo pip install -U --no-cache-dir sovrin but can you do pip install -U --no-cache-dir sovrin in your virtual environment. That should resolve the issue since the correct genesis files will be copied in your .sovrin

[howardkitto]

@lovesh I'm now running on an Ubuntu VM

I ran:

pip install -U --no-cache-dir sovrin

I get this:

@howardkitto Is your VM using bridged networking, or NAT? If NAT, I recommend that you try bridged. I'm not sure that this is necessary, but it eliminates one possible translation layer that might have gotchas.

Hi @howardkitto
We updated test cluster. It should be OK now. I recommend you to do the following:
0. Remove current sovrin setup from system if it is not in python virtualenv.

1. Setup python virtual environment
2. Install sovrin to it
3. Try Faber test from "Sovrin Getting Started" to check it.

BTW: I've instantly reproduced your problem with empty pool_transactions_sandbox file. But it was once in docker image. In virtual environment it works fine.
Now WSECUC has a correct IP address in that file, so sovrin is able to connect to it.
