Respun ISOs

As examples of using my ‘‘ script I’ve created various ISOs including those suitable for Intel Atom and Intel Apollo Lake devices.

Ubuntu 21.04 (Hirsute Hippo)

Canonical have announced the latest release of Ubuntu 21.04 (Hirsute Hippo):

Atom (-i ubuntu-21.04-desktop-amd64.iso --atom)

Apollo (-i ubuntu-21.04-desktop-amd64.iso --apollo)

Lubuntu 21.04 (Hirsute Hippo)

Canonical have also announced the official 20.04.1 flavours of Ubuntu including Lubuntu:

Atom (-i lubuntu-21.04-desktop-amd64.iso --atom)

Ubuntu 20.04 LTS - 20.04.2 (Focal Fossa)

Canonical have released the second point release of Ubuntu 20.04 Long-Term Support (LTS) as Ubuntu 20.04.2:

Atom (-i ubuntu-20.04.2-desktop-amd64.iso --atom)

Apollo (-i ubuntu-20.04.2-desktop-amd64.iso --apollo)

I've also respun the 'Focal Fossa' desktop ISO with the '--server' option to create a pseudo server ISO suitable for Intel devices with a 32-bit bootloader:

Server (-i ubuntu-20.04.2-desktop-amd64.iso --server)

Lubuntu 20.04 LTS - 20.04.2 (Focal Fossa)

Canonical have also announced the official 20.04.1 flavours of Ubuntu including Lubuntu:

Atom (-i lubuntu-20.04.2-desktop-amd64.iso --atom)

Ubuntu 18.04 LTS - 18.04.5 (Bionic Beaver)

Canonical have released the fifth point release of Ubuntu 18.04 Long-Term Support (LTS) as Ubuntu 18.04.5:

Atom (-i ubuntu-18.04.5-desktop-amd64.iso --atom)

Apollo (-i ubuntu-18.04.5-desktop-amd64.iso --apollo)

Downloading Note

After downloading an ISO file it is recommended to test that the file is correct and safe to use by verifying the integrity of the downloaded file. An error during the download could result in a corrupted file and trigger random issues during the usage of the ISO.

The program 'md5sum' is designed to verify data integrity using the MD5 (Message-Digest algorithm 5) 128-bit cryptographic hash. The MD5 calculation gives a checksum (called a hash value), which must equal the MD5 value of a correct ISO.

First open a terminal and go to the correct directory to check a downloaded ISO. Then run the command 'md5sum <ISO>' for example:

md5sum linuxium-atom-ubuntu-21.04-desktop-amd64.iso

'md5sum' should then print out a single line after calculating the hash:

2a16ded012decf9c5533692b7d0231f9 linuxium-atom-ubuntu-21.04-desktop-amd64.iso

Compare the hash (the alphanumeric string on left) from your output with the corresponding hash below. If both hashes match exactly then the downloaded file is almost certainly intact. However if the hashes do not match then there was a problem with the download and you should download the file again.

Creating a LiveUSB

Once you have verified your ISO it is necessary to write it to an USB to create an installation USB often known as a LiveUSB as not only can you install Ubuntu from it but you can also run Ubuntu for diagnostic, testing and fixing and existing installation.

There are several ways to write the ISO to USB however I recommend using Rufus on Windows or dd on Linux:

dd if=linuxium-atom-ubuntu-20.04.1-desktop-amd64.iso of=/dev/sdX bs=4M

where ‘linuxium-atom-ubuntu-20.04.1-desktop-amd64.iso’ is your ISO and ‘sdX’ is the USB drive using ‘ls -l /dev/disk/by-id/usb* | head -1 | sed "s?.*/??"‘ to determine this.

Respun ISOs Questionnaire

Whilst the latest version of version of '' supports the respinning of the latest Ubuntu and Ubuntu flavoured 20.10 (Groovy Gorilla) ISOs I don't have sufficient space available at the moment to post an example ISOs similar to those posted here.

So I've created a questionnaire to ask which ISOs are required both now and in the future.

There are only three sections:

Types of ISOs

Distro releases

Future ISOs

containing a total of 10 questions requiring a simple 'yes' or 'no' answer and a final open-ended question.

Please complete the questionnaire to ensure your opinion and needs are heard.

If you find the script or ISOs useful please donate using the following link as everything helps with development costs.
