Error connecting to MCP server

[Rachel Leach]

Hi, 

I used the manual install instructions (which are great, by the way!) to install the newest Archivematica release on Ubuntu 18.04. I have the dashboard and the storage service running on the same server. Everything went smoothly, but I hit a snag connecting the storage service. 

On the top right of my dashboard, I see "Error trying to connect to MCP server. Trying again..." 

The MCP server is running, but when I run "systemctl status archivematica-mcp-server', I see the following error: 

● archivematica-mcp-server.service - Archivematica MCPServer

   Loaded: loaded (/lib/systemd/system/archivematica-mcp-server.service; enabled; vendor preset: enabled)

Any advice on how to get these connected? Thank you!

In case anyone else runs into this issue, I was able to resolve it by installing additional language packs for my region and then resetting my locale.

Hi, I got the same problem, the UBUNTU 18 server I am using was installed in Brazilian Portuguese.

And what I did was:

By installing MCPServer and Dashboard, I got the warning: "setlocale: LC_ALL: cannot change locale (en_US.UTF-8)"

So, followed the instructions here, but instead of doing it for Portuguese, I did for English.

1.Type:

locale -a

--> Notice it didn´t listed "en_US.UTF-8"

2. Then type:
sudo nano /etc/locale.gen

-->find the line "en_US.UTF-8", =delete the "#" in front of it (uncomment) and save it.

3. Type:
sudo locale-gen

4. Then type again:
locale -a

--> Notice the "en_US.UTF-8" listed

Hope that helps.
