[Bug 1893146] Re: Ubuntu 18.04 crashes during installation in Virtualbox 6.1 on Windows 10 2004

[Chris Guiver]

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 :-

Aug 27 00:44:40 ubuntu kernel: [  154.633103] SQUASHFS error: zlib decompression failed, data probably corrupt
Aug 27 00:44:40 ubuntu kernel: [  154.633108] SQUASHFS error: squashfs_read_data failed to read block 0x43e4b54

Examining the information you have given us, this does not appear to be
a useful bug report so I am closing it, as it appears to be a bad ISO or
faulty device (inc. bad write-to-device). If you believe I'm in error,
please leave a comment explaining why and change the status back to
'New'. 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.

Possibly useful : https://tutorials.ubuntu.com/tutorial/tutorial-how-to-
verify-ubuntu#0 and

CD refers to your install media, be it CD, DVD, HDD, SSD, thumb-drive
etc)
