Downgraded to v3 but why does apt-get install fail?

I got a new WD My Cloud 3TB. It came with v4 firmware pre-installed, so I downgraded it using the “[Tutorial][SSH Method] Downgrade v4 firmware to v3” article.

Next I want to install the debootstrap package, but the system doesn’t let me. Any idea why?

After the downgrade reset, the web interface says “v03.04.01-219”. Then I do through ssh:

# apt-get update
(works ok)
# apt-get --force-yes install debootstrap
Reading package lists... Done
Building dependency tree 
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
sq : Depends: wddispatcher but it is not installable
Depends: wdnotifier but it is not installable
Depends: wdmpserver-sq-release but it is not installable
Depends: comm-manager-armhf-release but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

When I run apt-get -f install, the system offers to uninstall sq. What does that package do anyway? Am I ok to remove it?

# apt-cache show sq

Hmm, I’m guessing my problems stem from this  message while doing the downgrade:

Unpacking replacement sq ...
dpkg: sq: dependency problems, but configuring anyway as you requested:
 sq depends on wddispatcher; however:
  Package wddispatcher is not installed.
 sq depends on wdnotifier; however:
  Package wdnotifier is not installed.
 sq depends on wdmpserver-sq-release; however:
  Package wdmpserver-sq-release is not installed.
 sq depends on comm-manager-armhf-release; however:
  Package comm-manager-armhf-release is not installed.

Anyone know what’s going on here? :slight_smile:

During the downgrade, I also got loads of ‘Killed’ messages on ssh… I’m guessing not good news. Perhaps the firmware version I started off with cannot be downgraded using this method ?
