Install fail on Crucial M.2 from SD card via reader

[Dgorst]

Failure of package instaaller around halfway through copying files. Can't send if it's anything specific to Ubuntu or my hardware in the logs. Looks like zlib is failing but not sure if on read or write :

[ 189.071310] SQUASHFS error: zlib decompression failed, data probably corrupt

Trying with a different install media (currently using a 32GB SD card via USB reader for the Ubuntu image). Will try a different card.

Works perfectly on a small (8GB) USB stick, so either something to do with
Sandisk SD card or the reader (tried multiple SD cards).

The following messages can be found in UbiquitySyslog.txt which was automatically attached to this bug report:

Probably a bad write to your 32Gb SD card.
Closing as report is now almost 2 years old and the 18.10 release is now EOL.
