Everything runs smoothly when I execute sudo apt update, displaying the message "27 packages can be upgraded." However, issues arise when I proceed with sudo apt upgrade, as a few errors are encountered, as shown below:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
I attempted to resolve the issue by following the error message and running sudo apt update --fix-missing, but unfortunately, the error message remained unchanged.
I have listed all the methods I found online and attempted to debug the problem, but the error persists. If you have any additional suggestions or solutions, I would greatly appreciate your assistance in resolving this matter.
<Attempt 1>
"Failed to fetch security undetermined error ... | askUbuntu":
sudo nano /etc/apt/sources.list
I added the following lines to the file editor:
deb http:// archive.ubuntu.com/ubuntu focal main universe multiverse restricted
deb http:// security.ubuntu.com/ubuntu/ focal-security main multiverse universe restricted
deb http:// archive.ubuntu.com/ubuntu focal-updates main multiverse universe restricted
sudo apt clean && sudo apt autoclean
sudo apt update
There was no error on running these codes. However, I still received the same error when I attempted to run sudo apt upgrade.
<Attempt 2>
"apt-get update" always failed to fetch | askUbuntu":
sudo apt-get clean
sudo rm -rf /var/lib/apt/lists/*
sudo-get clean
sudo-get update
sudo-get upgrade
No errors occurred until sudo-get upgrade, and the error remained identical to the one mentioned earlier.
<Attempt 3>
"Install openjdk-8-jdk":
sudo apt update
sudo apt install openjdk-8-jdk-headless
When executing sudo apt install openjdk-8-jdk-headless, the same error as mentioned above occurred.
<Attempt 4>
"Could not get lock ...":
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock*
sudo dpkg --configure -a
sudo apt update
<Attempt 5>
"Fail to install openjdk-8-jdk | Ubuntu":
sudo apt update
sudo apt clean
sudo apt -y full-upgrade
sudo apt -y install openjdk-8-jdk
sudo apt-get -f install
wget http://security.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jdk-headless_8u312-b07-0ubuntu1~18.04_amd64.deb
Based on the information provided by ChatGPT, it is probable that the issue could be related to network stability. Nonetheless, my network functions smoothly, and I can install other packages without encountering any difficulties. Hence, I don't believe network stability is the reason for the problem. Additionally, I followed the suggestion to wait for a day, as it mentioned that server issues or network problems might be temporary and can sometimes resolve themselves after a few days.
As a newcomer to Linux, I am encountering difficulties dealing with these errors. If you have any additional suggestions or solutions, I would greatly appreciate your assistance in resolving this matter.
