Where can I get the old repositories for Ubuntu versions? In my case, it's 9.04 Jaunty?
I found all the official repositories and their mirrors have been removed. I am wondering where I can get the repository list for this version?
Your system is End-of-Line (EOL), therefore not officially supported. Unless you have a good reason for sticking with 9.04, upgrade to a newer version. 18.04 is the next long-term supported release for Ubuntu, which will continue to receive updates.
To access old Ubuntu repositories, take a look at http://old-releases.ubuntu.com/.
There is also an official Ubuntu documentation for EOL upgrades
They say you should be able to access your packages by putting the following into
/etc/apt/sources.list. Important: Change
CODENAME to your distribution's code name, e.g.
## EOL upgrade sources.list # Required deb http://old-releases.ubuntu.com/ubuntu/ CODENAME main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-updates main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-security main restricted universe multiverse # Optional #deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-backports main restricted universe multiverse
apt-get update and you can use them.
