[Bug 1857553] Re: 18.04 Live Failed to install

[Paul White]

Thank you for taking the time to report this issue and helping to make
Ubuntu better.

This package failure looks like it was caused by bad ISO download,
corrupted install media, or device failure. eg. look in the logs and
you'll see messages like these :-

>>Dec 25 18:34:25 ubuntu kernel: [  579.456379] SQUASHFS error: zlib decompression failed, data probably corrupt
>Dec 25 18:34:25 ubuntu kernel: [  579.456383] SQUASHFS error: squashfs_read_data failed to read block 0x116c2df

I suggest you verify your ISO download, and use the 'check disc for
defects' option to validate your media before install to ensure a good
download & write.

verify-ubuntu#0 and

refers to whatever install media you use, inc. usb thumb-drive)
