Answer 1

UPDATE: thanks to smknstd, JoeCool, MDarrinT and PurplProto.

Script is working again.

You can chose 3 different methods:

# First method, upgrade to 22.04 with the official ubuntu method ( old-releases.ubuntu.com )
# Replace sources.list   
text="deb http://old-releases.ubuntu.com/ubuntu/ hirsute main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ hirsute-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ hirsute-security main restricted universe multiverse"
sudo echo "$text" | sudo tee /etc/apt/sources.list
# Prerequisites
sudo apt-get update
sudo apt-get install update-manager-core update-manager -y
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y 
# Download and run the ubuntu upgrade tool
wget http://archive.ubuntu.com/ubuntu/dists/jammy-updates/main/dist-upgrader-all/current/jammy.tar.gz
tar -xaf jammy.tar.gz 
sudo ./jammy --frontend=DistUpgradeViewText

-------------------------------++++++++++++++++++++++++--------------------------------

# Second method, upgrade to 22.04 replacing the entire sources.list with the jammy repos
# Replace sources.list   
text="deb http://archive.ubuntu.com/ubuntu/ jammy main universe restricted multiverse
deb-src http://archive.ubuntu.com/ubuntu/ jammy main universe restricted multiverse
deb http://security.ubuntu.com/ubuntu jammy-security main universe restricted multiverse
deb-src http://security.ubuntu.com/ubuntu jammy-security main universe restricted multiverse
deb http://archive.ubuntu.com/ubuntu/ jammy-updates main universe restricted multiverse
deb-src http://archive.ubuntu.com/ubuntu/ jammy-updates main universe restricted multiverse"
sudo echo "$text" | sudo tee /etc/apt/sources.list
# Bypass "An upgrade from 'xxx' to 'xxx' is not supported with this tool" error
sudo sed -i 's/continue/pass/g' /usr/lib/python3/dist-packages/UpdateManager/Core/MetaRelease.py
# Start upgrade
sudo apt-get update
sudo do-release-upgrade
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y
sudo apt-get install -f -y
sudo apt-get autoremove --purge -y
       
-------------------------------++++++++++++++++++++++++--------------------------------

# Third method, upgrade to 22.04 replacing the current distro codename with jammy into the sources.list with sed
# Replace sources.list  
sudo sed -i 's/hirsute/jammy/g' /etc/apt/sources.list
# Bypass "An upgrade from 'xxx' to 'xxx' is not supported with this tool" error
sudo sed -i 's/continue/pass/g' /usr/lib/python3/dist-packages/UpdateManager/Core/MetaRelease.py
# Start upgrade
sudo apt-get update
sudo do-release-upgrade
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y
sudo apt-get install -f -y
sudo apt-get autoremove --purge -y

Answer 2

Well, I tried the approach above. It failed.

Going through the script, I decided to check the Ubuntu server for the packages. Strange, there are all these NotFound errors. Guess what? The apt files referenced were missing from the Ubuntu server.

Then I went in and changed all the hirsute labels to jammy in the /etc/apt/sources.list file. Once I did that, apt ran. I could then run the script indicated above and have it find the packages.

Now, it works. A couple of messages about php-fpm not being enabled under Apache HTTP, but since I run nginx, I hope it works.

And it worked. I had to run through the apt upgrade && apt update && apt dist-upgrade && apt autoremove to clean out the detritus, but I have a working install on LTS.

Answer 3

official (unsupported) upgrade path from EOL is described here:

https://help.ubuntu.com/community/EOLUpgrades

and requires pointing apt to old-releases.ubuntu.com mirror

Answer 4

Before running the script, I had to modify my sources.list (/etc/apt/sources.list) and comment-out all lines leaving only these:

## EOL upgrade sources.list
# Required
deb http://old-releases.ubuntu.com/ubuntu/ jammy main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jammy-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jammy-backports main restricted universe multiverse

Then it went first to 'impish' and then to 'jammy' by running the script twice.

Or you can sudo do-release-upgrade after the first script; from 'impish' to 'jammy'.

Thank you and voted-up your answer.
