When I run the do-release-upgrade
command in the terminal, I receive the following error message:
Checking for a new Ubuntu release
Traceback (most recent call last):
File "/usr/bin/do-release-upgrade", line 164, in <module>
if m.new_dist.upgrade_broken:
AttributeError: 'NoneType' object has no attribute 'upgrade_broken'
I have already taken the following steps to troubleshoot the issue:
- Ensured that my package lists are up to date using
sudo apt update
andsudo apt upgrade
. - Cleaned the package cache with
sudo apt clean
.
I am currently running Zorin OS 16.2
