I encountered an issue while running sudo apt update on my system. The error message I received is as follows:
sudo apt updateHit:1 https://dl.yarnpkg.com/debian stable InReleaseHit:2 https://deb.nodesource.com/node_20.x nodistro InReleaseHit:3 http://in.archive.ubuntu.com/ubuntu jammy InReleaseHit:4 http://in.archive.ubuntu.com/ubuntu jammy-updates InReleaseHit:5 http://in.archive.ubuntu.com/ubuntu jammy-backports InReleaseHit:6 http://in.archive.ubuntu.com/ubuntu jammy-security InReleaseHit:7 https://download.docker.com/linux/ubuntu jammy InReleasesh: 1: /usr/lib/cnf-update-db: not foundReading package lists...

Additional Information:
Operating System: UbuntuVersion: Jammy (22.04)This issue seems related to the absence of /usr/lib/cnf-update-db.
I tried reinstalling the command-not-found package using the command
sudo apt-get install --reinstall command-not-found
I encountered an error indicating unmet dependencies, prompting the recommendation to try resolving them with:
sudo apt --fix-broken install
However, executing this command led to further issues. Processing of the python3-minimal package encountered errors, resulting in the failure of the dpkg process with an error code (1). Additionally, the needrestart task was skipped due to this failure.
In an attempt to address the problem, I proceeded to remove the python3-minimal package with
sudo apt remove python3-minimal
Yet again, I faced an error concerning unmet dependencies, and the suggestion to resolve them using:
apt --fix-broken install
