Error Installing Ubuntu on Pi5

Using the Pi image writer I wrote the Ubuntu Desktop 24 LTS onto a flash drive. The pi booted with Ubuntu and I went through the initial setup. Then, upon completing filling the username and password, the setup halted displaying an error. Error displayed ‘The installer encounterd an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again.’ Upon clicking ok on the error message the system rebooted. While shutting down to reboot, I saw in the process a line ‘Failed to start pd-mapper’, though not sure if it is relevant. However, upon reboot, Ubuntu does not accept my previously configured username and password. I am neither able to ssh into it though I had enabled it in the image writer settings nor does the usual recovery option work on the pi. How should I proceed?

Do you have a link to the Ubuntu Desktop 24 LTS?

Used the image writer’s inbuilt option by selecting other OS
