A complete operation from Microsoft SharePoint 2013 or Microsoft SharePoint 2010 will fail and you will immediately see the following COMException error message logged in the ULS associated with the SharePoint LogViewer:

Reason

This usually happens after the supervisor logs into the server for online visit with a service account and then logs off. For example, an administrator can log into a front-end Web server (WFE) with someone else’s farm account and then log off. This action dumps the registry keys to this bank account profile. This state makes the keys unavailable.for future use.

Resolution

Method 1

Do not log in to positively serve interactive sessions using a service account.

Method 2

Disable the Windows User Profile Service feature. To stick with this, follow these steps:

1. Open the Group Policy Writer (Gpedit.msc) on the affected server.

2. Open the UserProfiles folder in the following path:

   Computer Configuration> Administrative Templates >> System User Profiles

3. 

   Find some settings. Do not force the user’s Windows registry to be unloaded when the user logs off.

4. Return the parameter to On.

My damaged shell was at first in an account without administrator rights. After reading these articles, I logged in as an administrator and started the Ubuntu shell. The post first talked about reformatting the file, which allowed the shell instance to function normally.
However, I uninstalled Ubuntu from Applications / Services and then accepted my non-admin account again, combined with reopening Ubuntu. All perfectly.

My damaged shell was associated with a non-admin account. After reading articles like this, I logged in as an administrator and also started the Ubuntu shell. The post was mainly related to a file reformat that allowed my shell instance to work fine.
However, I still locked Ubuntu for apps / services and then logged in to my non-admin account and reopened Ubuntu. All perfectly.
