cannonballSpamapS: I don't know if you saw the followup email, but I was able to get the Quantal version of cups 1.6.1 to build on precise (is that right? 12.04)01:08
cannonballI had to comment on one line of the apparmor profile for the cupsd binary, but then it started up just fine using my old cupsd.conf.  Now the ios 6 devices see the printer instantly.01:09
cannonballI also think that your method looks a LOT simpler than the way that I did it, but I now have a _slightly_ better understanding of what is going on during deb builds.01:09
cannonballJust slightly though...there's still a lot going on in the background (tons and tons of dh* commands rolling by) that I don't yet grok. :-)01:10
cannonballThanks for the feedback, see you at a LUG or maybe SCALE.01:10

cjwatsondoko: already known, reported upstream (http://hackage.haskell.org/trac/ghc/ticket/7316), and not likely to be fixed for 12.10.  I already removed all the out-of-date binaries affected by this.15:17

jamingot caught by a pretty nasty regression when I upgraded from 12.04 to 12.10: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/106632419:36
ubottuLaunchpad bug 1066324 in grub2 (Ubuntu) "core.img too large for embedding with msdos partition style" [Undecided,New]19:36
jaminfor some reason, 12.10's core.img generation results in larger files than 12.04's19:40
jtaylorhad that too :/19:40
jtayloror still have it, but I resized my boot sector to fix it19:41
jaminso, combinations that worked perfectly under 12.04 no longer work under 12.10 and sadly you don't find out (or at least I didn't) until you try to reboot19:41
jtaylorwhen did you setup the partitioning of your machine?19:41
jtaylorif you pay attention during upgrade you do find out19:41
jaminit's changed over time19:41
jaminjtaylor, had no warning during the upgrade...19:41
jtaylorthere should be a message that core.img is to large19:42
jtaylorbut its easy to overlook19:42
jaminif there was, I overlooked it... should be pretty big blocker19:42
jtaylorit kind of sucks that you land in a rescue prompt then instead of grub being left unchanged19:42
jaminas for the partitioning, I migrated the system into purely LVM during its 12.04 lifetime... but had no issues with grub after19:43
jaminyes... if grub had been unchanged it would still have worked... and rescue prompt is rather useless at this point19:43
jaminhad to move the system to a GPT partition table to resolve it19:44
jtaylorjust sizing it to a sane size is enough19:44
jtaylorunfortunately that takes ages19:44
jamineven though there was a full 1M at the start of the drive before the first partition19:44
jtaylorok that is different than what I had19:45
jtaylorsizing it to 1M fixed it for me19:45
jaminit's solved for me now, but I can't image that I'm the only person that has everything residing inside LVM with an MSDOS style partition table19:46
jtaylorcjwatson: you may want to look into that again ^19:46
jtaylorI hit it at the time bug 1051154 was opened, after resizing and the bug being closed I didn't bother about it anymore19:47
jaminwould love to know why the core.img has increased in size from 12.04 though...19:47
ubottuLaunchpad bug 1051154 in grub2 (Ubuntu) "mdraid1x core image too large for minimal MBR?" [High,Fix released] https://launchpad.net/bugs/105115419:47
jtaylorbut my core.img is still larger than 32k19:47
jaminjtaylor, yea, I read that report... seemed like an off by 1 bug based on the feedback... but that doesn't seem to be what I'm running into19:48
jaminjtaylor, what's the exact size of yours now?19:48
jtaylor3329419:48
jaminodd, even larger than mine... so if your's fit, mine should have19:49
jtaylorI now have 2024 sectors at the start19:49
jtaylorit where 64 before19:49
jaminmaybe there wasn't a full 1M free at the start before I moved to GPT...19:50
jtaylorwhat does sudo fdisk -l /dev/boot-device say for the start?19:50
jamincould have sworn there was19:50
jaminI've repartitioned the device now19:50
jaminbooted to a live-cd attached an external drive and pvmoved all the volumes off the internal drive... then repartitioned as GPT and pvmoved them all back19:51
jaminthough I think I saved the partition table layout as a precaution... let me see19:51
jaminjtaylor, looks like it started at 6319:56
jaminfound the backup file... *sigh*19:56
jtaylorI'm going to mark it critical, my machine was not partitioned to long ago (about 1-2 years) so its probably a not to uncommon thing19:57
jtaylorand very hard to fix for inexperienced users19:57
jaminvery19:57
jaminI believe that everything in lvm is one of the automatic partitioning configurations for partman isn't it? or does that one keep /boot out?20:02
jtaylordon't know20:06
jtaylorI too use lvm, probably its somehow related to it20:07
jtaylorwould explain why there aren't more reports of this20:07
jaminit is related to lvm... if you rebuild core.img without the lvm module it's small enough to fit20:09
jaminand looking at the automated recipes, they all appear to have /boot outside the lvm volume20:10
cjwatsonjamin,jtaylor: it'll definitely fit in 1MB.  As for the case where you only have 63 sectors at the start, no Ubuntu installer for the last few years will produce that layout by default, and I'm afraid I have approximately zero likelihood of being able to fix it by release20:46
jtaylorcjwatson: figured as much, as it only appears to affect lvm feel free t reduce the importance or set it won't fix20:47
jamincjwatson, then it's safe to say that a number of people are going to wind up with unbootable boxes20:47
cjwatsonjamin: yes20:47
cjwatsonbut I can't fix it20:47
cjwatsonnot in time anyway20:47
cjwatsonwe'll have to release-note it20:48
jamineven if it's not "fixed" in an automated fashion is it not possible to have it seriously error in an in your face sort of fashion?20:48
cjwatsonnot in time20:48
cjwatsonI mean, that's the only terribly plausible way to "fix" this at all20:48
cjwatsonbut I have sooooooo many things to do20:48
cjwatsonof course people would complain about the resulting upgrade failure too, and it's not like moving partitions around is an easy thing to do20:49
jaminhow about an upfront check?20:49
cjwatsonit would at best defer the upgrade failure20:49
cjwatsonor defer the boot failure20:49
jaminsomething at the start of the upgrade process that checks for only 63 sectors on the drive?20:49
cjwatsonif somebody else wants to attempt that ...20:50
cjwatsonit won't be me20:50
cjwatson(and of course plenty of layouts do still work fine with 63 sectors, particularly after I fixed the off-by-one error in grub-setup)20:50
jaminany reason the core.img increased in size?20:50
cjwatsonno very straightforward way to tell which in advance, without having the upgraded code20:50
cjwatsongrub 1.99 -> 2.00 - various bug fixes which involved bigger code20:50
jaminguessing it's not possible to get it back down to 12.04 size20:51
cjwatsonno single cause20:51
cjwatsonit may be possible but requires serious work; I looked and there was no single obvious smoking gun20:51
cjwatsonjust general drift20:51
jaminI'd think a blanket warning for any 63 sector configuration would be better than waiting to see which can no longer boot20:51
cjwatsonI don't mind if somebody else wants to do that20:51
cjwatsonlike I say, it's simply not physically possible for it to be me at this point, due to lack of hours20:52
jaminyea, understood... just thinking of the fallout if this hits any decent number of users20:52
cjwatsonnearly every boot loader bug is critical for those it hits20:52
jaminagreed, just never seen one from an upgrade like this20:53
cjwatsonyours is likely because of the combination of GPT and LVM; I'm fairly sure MBR and LVM fits20:53
jaminnope... was MBR and LVM that caused it20:54
cjwatsonoh, wait, your grub-install debug output was from after you moved from GPT20:54
jaminmoved to GPT to resolve it20:54
cjwatsonway to file a confusing report :P20:54
jaminyes20:54
jaminsorry... couldn't file from a non-bootable system20:54
cjwatsonbetter not to mention the grub-install debug output then - I'll delete it from the description as it's actively misleading20:55
jaminsounds like I could have stayed with MBR if I'd just moved my partitions down to start at 1MB in20:55
cjwatsonYes20:55
jaminsorry... wanted to show which modules were being used20:55
cjwatsonThat's the default partitioner configuration since 10.0420:55
cjwatsonNow, gparted may be stupid20:56
cjwatsonI mean the actual Ubuntu installer partitioner20:56
jamingparted puts it at 1M20:56
cjwatsonConfusing given jtaylor's comment, unless that was a more recent fix20:56
jtaylorI think I used gparted in default config for my setup20:56
jaminI'd replaced the drive and migrated the installation from rotation to ssd20:56
cjwatsonBear in mind that gparted may have different defaults for SSD20:56
jtaylorbut maybe I also left the boot partition at stock settings20:56
jtaylorits been a while20:57
cjwatsonlibparted typically tries to pick up the topology from the driver20:57
cjwatson*drive20:57
cjwatsonSo this kind of thing basically only affects people who've done by-hand partitioning with non-default tools, or who've upgraded since before 10.0420:57
jaminthink I may have used cfdisk to layout the partition on this SSD originally20:57
cjwatsonYeah, cfdisk is dark-ages stuff20:57
jaminseeing that now... =(20:58
cjwatsonI don't believe it's really kept up with modern alignment requirements and such20:58
