update manager fails 8.04 -> 10.04 when /tmp is mounted noexec

Ubuntu 8.04 is fully up to date :

sudo apt-get dist-upgrade

Running update manager as a user fails silently:

update-manager --devel-release

authenticate 'lucid.tar.gz' against 'lucid.tar.gz.gpg'

Running as root yields:

Bodhi, can you please attach the log files /var/log/dist-upgrade/ to the report. Thanks in advance.

I have tried upgrading a clean, fully upgraded install of 8.04.3 to 10.04, and have had no issues whatsoever during the process.

Bodhi, as a hunch, can you please post your fstab listing.

Knowing you, you may have some weird security mount settings in place that is preventing upgrade from taking place, ie: /tmp is mounted as noexec.

Regards
Iain

Oh , so that's why I was getting permission denied.

/tmp was mounted noexec

Never had a problem with that before w/ update manager

At any rate the upgrade is proceeding now, it reports it will take 5 hours or so, I will update you all tomorrow.

Thanks Iain =)

[Iain Buclaw (iainb)]

No problem Bodhi, as they say, it takes one to know one. And I doubt I would have suggested it if you were a complete stranger to me.

The update went through, I had two errors flash by during the upgrade, one on flashplugin-nonfree and the other on apparmor.

I *did* have a few custom apparmor scripts and will have to look at both of these problems in more depth as time allows.

Thank you once again Iain

Thanks for this report.

I'm setting the status to 'triaged' since /tmp mounted as noexec is blocking the upgrade. If that's not a bug in update-manager it requires at least some documentation.

[Iain Buclaw (iainb)]

If that is the direction forward we want from this, it is probably in best interest to hint that mounting as 'user' automatically implies noexec too.
