[07:56] <ara> good morning all!
[08:13] <ara> mvo, morning!
[08:23] <mvo> hey ara, good morning
[08:39] <ara> hey mvo, upgrading question: O:-)
[08:40] <mvo> ara: sure
[08:40] <ara> mvo, yesterday, I upgraded a mini9 running UNE (i had just installed it, so very clean) to 10.10 (Unity) and it took 6 hours!
[08:40] <ara> is that normal?
[08:41] <ara> well, a mini9 does not have a core i7, but still...
[08:41] <mvo> 6h - woah
[08:41] <mvo> that is a *long* time
[08:42] <mvo> ara: most of this time was dpkg running, I assume? not the download?
[08:42] <ara> yes, and it wasn't downloading time, I promise :-)
[08:42] <ara> mvo, :D
[08:42] <ara> mvo, dpkg running
[08:42] <mvo> I have one atom machine that I can test today and debug
[08:42] <mvo> ara: how much memory? 1gb I assume?
[08:42] <ara> yes
[08:43] <mvo> ssd ? or normal hdd?
[08:43] <ara> hdd
[08:43] <mvo> thanks :)
[08:44] <mvo> that should be enough info so that I can reproduce
[08:44] <ara> mmm, maybe ssd, let me double check
[08:44] <ara> mvo, do you want me to file a bug so you can track progress?
[08:44] <mvo> please
[08:44] <ara> against update-manager?
[08:44] <mvo> yes
[08:44] <mvo> if ssd it would be even more disturbing, but my first guess would be that its hitting swap a lot
[08:45] <jibel> ara, is it slow if you simply use dpkg ?
[08:45] <jibel> ara, which type of fs ?
[08:46] <mvo> good morning jibel
[08:47] <jibel> good morning mvo ! how are you ?
[08:47] <ara> jibel, ext4
[08:49] <mvo> jibel: good, thanks! how are you? crazy amounts of sru? a bit more quiet? I think I got most of software-center ready now, I'm quite happy about that
[08:50] <jibel> mvo, pitti is busy on other things, so that's rather quiet :-)
[08:50] <mvo> ara: perfect timming btw, I got a spare notebook hdd just yesterday for this kind of testing
[08:50] <mvo> jibel: haha :)
[08:50] <mvo> jibel: excellent, we should keep him busy
[08:50] <ara> mvo, nice :)
[08:55] <ara> mvo, it is an SSD
[09:00] <jibel> ara, that's probably bug 570805
[09:00] <ubot4> Launchpad bug 570805 in dpkg (Ubuntu Lucid) (and 3 other projects) "[regression] dpkg's fsync causes massive regression in Ubuntu Server and Alternate installation times (affects: 18) (dups: 1) (heat: 154)" [High,Fix released] https://launchpad.net/bugs/570805
[09:01] <jibel> ara, but this was fixed by changing to a global sync, so 6h is way too much.
[09:02] <ara> jibel, yes, but I didn't update Lucid before upgrading
[09:02] <ara> mvo, bug 646638
[09:02] <ubot4> Launchpad bug 646638 in update-manager (Ubuntu) "Upgrading from UNE 10.04 to 10.10 (Unity) took about 6 hours (affects: 1) (heat: 6)" [Undecided,New] https://launchpad.net/bugs/646638
[09:02] <jibel> ara, oh. what was the version of dpkg before the upgrade ?
[09:02] <ara> jibel, might be
[09:02] <ara> jibel, I don't know
[09:03] <ara> jibel, but it is stocked 10.04.1, so we can see on the release notes
[09:03] <ara> jibel, if it is previous that one, I will try again
[09:03] <ara> today updating before
[09:04] <jibel> ara, it was  dpkg 1.15.5.6ubuntu4
[09:04] <jibel> ara,  and the fix is in  dpkg 1.15.5.6ubuntu4.1
[09:05] <jibel> ara, are you able to install 10.04.1, upgrade dpkg to  1.15.5.6ubuntu4.1 or 4.3 and upgrade to maverick ?
[09:05] <ara> jibel, yes, I will do that today
[09:11] <jibel> ara, that's weird that 1.15.5.6ubuntu4 was installed with 10.04.1 because 1.15.5.6ubuntu4.1 is on the iso (at least desktop-i386)
[11:48] <ara> jibel, mvo: I am trying again, but now, I have the latest dpkg (I only updated that package) and it is still  very slow (it says 7 hours remaining...)
[11:49] <ara> is there any other package I should update?
[11:51] <jibel> ara, I don't think of any. Can you add the output of dmesg to your report ?
[11:51] <ara> jibel, sure, one it finishes I will
[11:51] <ara> (in about 5 hours) :D
[11:54] <jibel> ara, what's interesting is how the current kernel sees your drive and fs, so save the output before rebooting. You confirm that you use ext4 and not btrfs ?
[11:54] <ara> ext4
[11:54] <jibel> ara, so lets wait for 5 hours :)
