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.

If you experienced an issue during installation and think it is not caused by a corrupted installation media, do not hesitate to report a bug by running the following command from a terminal:

$ ubuntu-bug ubiquity

Thanks for using Ubuntu.
