"starttoinstall" fails

[situssoft]

Fails when unpacking the installer @ 74.4% regardless of how many times I download and which version of macOS I attempt to install.

Preparing 74.4% An error occurred validating the installer data. The download is either damaged or incomplete.

I've attempted this a few times now, I don't generally have any issues with my network or downloading fro the web.

Any help appreciated.

[situssoft]

Well, I tried a few more times, without deleting any of the downloaded files and eventually I've managed to get through to the install.

Sorry, no idea why this has been unreliable.

Could not reproduce. Closing until further details are provided.

Even I am facing the same issue.Mine stuck as 73.6% with the same message as above

Hi. Can you provide the md5sum for the *.part* files on the script's working directory on the host, the md5sum for the InstallESD.dmg file on the guest, upload the install.log file from the guest and VBox.log from the host?

---

The virtual machine log VBox.log is found in the VirtualBox VM log directory.

---

Installer log can be uploaded from the guest machine with the following Terminal command after the installer fails:

curl -F 'f:1=@/var/log/install.log' ix.io

---

Checksum of InstallESD.dmg can be computed on the guest machine with the following Terminal command:

md5 /Install*/Contents/SharedSupport/InstallESD.dmg

---

Checksums for the files split from InstallESD.dmg on the host machine can be computed by executing the following command at the script's working directory:

for part in *.part*; do md5sum "${part}"; done

My installer is consistently failing at 77.8%.

@kklopfenstein hi, thanks for the detailed bug report. The md5 checksums for the Catalina InstallESD.dmg version 10.15.5.0.0.1591330708 do not match.

These are the correct md5 checksums for the Catalina installer version 10.15.5.0.0.1591330708:

As you can see all the parts are correct but the complete Catalina_InstallESDDmg.pkg is damaged. There might have been an error concatenating the files.

Currently investigating the logs.

[myspaghetti]

All the VBox logs look good on first glance. Investigating the startosinstall logs

[kklopfenstein]

I've retried several times (with and without deleting temporary files). I get different checksums from InstallESD.dmg every time which seems in line with your concatenating theory.

[myspaghetti]

@kklopfenstein sorry, can't troubleshoot it any further.

The VirtualBox configuration and script configuration are good, except the unsupported display resolution which is unlikely to be related.

You might have found a memory paging bug in VirtualBox.

[kklopfenstein]

I reinstalled VirtualBox and retried the script with default settings (2 cpu, 4gb memory, 1280x800 etc). It worked the first time.
