Maint scripts exit status and apt.
I ran `dselect', and picked `ssh', along with a slew of other
packages, then pushed Install. When it popped up the `debconf'
interface for `Open-ssh', I answered No by mistake (Is the button red
or blue when it's active?). Here's what it said.
ssh preinst: Aborting because ssh/upgrade_to_openssh = false
dpkg: error processing /var/cache/apt/archives/ssh_1%3a1.2pre17-1_i386.deb (--unpack):
subprocess pre-installation script returned error exit status 1
Errors were encountered while processing:
E: Sub-process returned an error code (1)
Some errors occurred while unpacking. I'm going to configure the
packages that were installed. This may result in duplicate errors
or errors caused by missing dependencies. This is OK, only the errors
above this message are important. Please fix them and run [I]nstall again
Press enter to continue.
It then went and ran configures on what had been unpacked, and
dropped me back to the `dselect' main menu.
Here's the relevant portion of the "/var/lib/dpkg/info/ssh.preinst":
if [ "$RET" = "false" ]; then
echo "ssh preinst: Aborting because ssh/upgrade_to_openssh = false" >&2
You can see it exits with code 1.
I don't think that `apt' should have aborted there; it ought to have
continued on its way. We need to define some standard exit status
numbers for those scripts.
