[Bug 1901308] Re: Install Lubuntu as 2nd Linux OS - installer crash

[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 :-

Oct 24 11:42:55 lubuntu kernel: [  267.425966] SQUASHFS error: zlib decompression failed, data probably corrupt
Oct 24 11:42:55 lubuntu kernel: [  267.425974] SQUASHFS error: squashfs_read_data failed to read block 0x24fec17

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
https://help.ubuntu.com/community/Installation/CDIntegrityCheck  (where
CD refers to your install media, be it CD, DVD, HDD, SSD, thumb-drive
etc)
