I am facing a critical issue while attempting to upgrade my Ubuntu Server from 16.04 to 18.04. I have encountered an error that is preventing me from successfully completing the upgrade process. The error message I'm encountering is as follows:

No such file or directory
dpkg: error processing package shim-signed (--configure):
installed shim-signed package post-installation script subprocess returned error exit status 1
...
SyntaxError: invalid syntax
dpkg: error processing package sosreport (--configure):
installed sosreport package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
shim-signed sosreport

This issue has resulted in a situation where I am unable to access any menus on my Ubuntu Server. As a result, I am reaching out for assistance in resolving this matter and getting my server back up and running.

I have attempted the following solutions to address the problem, but unfortunately, they have not provided a resolution:

Executing the command:

sudo dpkg --configure -a
sudo apt-get install -f

Both attempts yielded the same result, and the issue persists.

If you require any additional information or logs to better understand the problem, please do not hesitate to ask.

Only releases of Ubuntu in *standard* support are on-topic on this site, thus the oldest *supported* release of Ubuntu is Ubuntu 20.04 LTS. You're trying to move from one off-topic or EOSS release (16.04) to another off-topic or EOSS release (18.04) thus are outside of what is on-topic for this site.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
