Cannot deploy Shadow manager on a GG device with GG v1 installed

Question

I have only 3 components in my deployment at the moment, log manager, Legacy Subscriptions, and shadow manager. Any time I start the deployment it fails and rolls back to the previous deployment with only log manager, and legacy subscriptions. My device has both Greengrass v1 installed and greengrass v2.

I've tried deleting the component folder within v2/work  after the failed deployment, but it does not seem to change anything
The following is the error within the greengrass log file after deploying:

Answer

Hello,

As a workaround suggested by the expert you could try the shutting down the GreenGrass v2 using the below command,
```
sudo systemctl stop greengrass 
```
Further, delete all the files of the shadow manager component by following the below command,
```
sudo rm -rf /greengrass/v2/work/aws.greengrass.ShadowManager
```
Lastly, restart the GreenGrass, to check if the issue was mitigated
```
sudo systemctl start greengrass
```
