full harddisk, skript crashes

[AndiG]

1) 0,5 GB free disk space
2) update && upgrade is close but less 0,5 GB
3) post install script crashes anyway (no space on disk left)

maybe the upgrade disk usage speculation should be more accurate or conservative, so the user provides more disk space by deleting files, or something like that.
