I am trying to image Ubuntu onto an SD card on my Mac for use with my Raspberry Pi 4 using thew new official imager tool from Raspberry Pi (found here: https://www.raspberrypi.org/downloads/). For whatever reason, every time I try to image any version of Ubuntu that is pre-selected from the Ubuntu OS Menu (v18.04.4 32 & 64 bit, v19.10.1 32 & 64 bit, and Ubuntu Core 18 32 & 64 bit), it completes the install, but at the verify stage it fails once it reaches 100%. Specifically, the error message reads
"Verifying write failed. Contents of SD card is different then(than?)
what was written to it." I know that the imager does work. I got it to install Raspbian without issue.
Moreover, I have tried downloading the
.xz file directly from Ubuntu (v18.04.4 LTS - https://ubuntu.com/download/raspberry-pi) and using the RPi imager with that file. It gives the same error message. I have also tried unzipping the file and using the
.img file with the imager and it gives a different error saying
Error writing file to disk.
So, the question is why won't it install Ubuntu? Since this installer is under 2 weeks old, I have not found much information elsewhere.
The steps I have taken:
- Download the imager from RPi (https://www.raspberrypi.org/downloads/)
- Erase and format SD card from imager option
- Select a version of Ubuntu from the OS menu, select SD card, select
- Imager writes 100% of the way, verifies up to 100% and then fails.
- Repeat steps 2-4 for all versions of Ubuntu with no luck.
If there is any more useful information I can provide, please let me know.
