cant install 19.04 says dirty cd/dvd or hard disk problem

[Kevin Rooyakkers]

I was reinstalling ubuntu 19.04 from a flash drive. I installed it once and the libre officer packages failed to install and it also installed my boot loader onto the wrong disk so it was not booting up. i installed it with the install ubuntu and erase disk option. The second time I installed manually, put the bootloader on the right drive and then started the installation. I got this error.

I got this same error attempting to install 19.04 earlier with a different flash drive so i dont know what to do now if something is wrong with my ssd drive.

You probably had a bad write to your media. If you have problems in the future please try the option to check the integrity of the image from the installer boot menu, and if this confirms that the media is corrupt, try re-writing it.

I'm closing this bug report due to the time that has elapsed since it was raised. Also Ubuntu 19.04 is now out of support.
