[master] nfs-common makes upgrade calculation impossible (was: Could not calculate the upgrade)

Could not calculate the upgrade
report bug against update-manager
Hardy Heron Alpha 2

I get this error "Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade. Please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report." I get this when running a partial upgrade as part of the normal update process in hardy heron. I don't know if its helpful or not to throw in my copies of these files so I will.

main.log and term.log also appear in my /var/log/dist-upgrade/ but they have not been modified in 4 days so I would imagine do not have relevant info if otherwise let me know.

Several duplicates. Setting to confirmed

The problem with the dapper->hardy upgrade calculation is that libnfsidmap1 has priority "standard" while libnfsidmap2 has priority "optinal". That makes apt prefer the former one over the later one and that breaks the upgrade.

The alternative to updating the priority would be to add a (empty) transitional libnfsidmap1 package.

Unfortunately this can not be fixed with a quirks rule in update-manager because the apt resolver breaks in cache.upgrade(True) already before any quirk rules can be applied.

I uploaded a new util-linux package that adds a conflicts against libnfsidmap1 to mount. That helps the resolver remove it early. I milestone this as it breaks for a lot of dapper users (with nfs-common installed).

  This package provides the mount(8), umount(8), swapon(8),
  swapoff(8), and losetup(8) commands.

I just verified the fix in my automatic upgrade tester, with the updated package it works, without it it fails.

Accepted into hardy-proposed, please test.

This is not relevant for intrepid, only for dapper->hardy upgrades.

I have verified the fix by following the test case provided. Without dapper-proposed enabled I was unable to calculate the upgrade when nfs-common was installed. After enabling dapper-proposed the upgrade was calculated and started successfully.

Copied to hardy-updates.

It's possibile there are problems with the ntfs-3g? I've problem with myfstab configuration...
