Public bug reported:

If you have been redirected to this page, it means that your
installation of Ubuntu or a flavour failed.

If you look in the log file /var/log/syslog, you'll see messages like
the above:

Apr 24 00:01:40 ubuntu kernel: [  329.409695] SQUASHFS error: zlib 
decompression failed, data probably corrupt
Apr 24 00:01:40 ubuntu kernel: [  329.409704] SQUASHFS error: 
squashfs_read_data failed to read block 0x37545

This failure is usually caused by bad ISO download, corrupted install
media, or device failure.

We suggest you verify your ISO download, and note the validation of your
ISO before install to ensure a good download & write.
