[Kernel-packages] [Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
This seems to be fixed in the latest released kernel for ubuntu 14.04: $ uname -rvp 3.13.0-83-generic #127-Ubuntu SMP Fri Mar 11 00:25:37 UTC 2016 x86_64 In both this desktop and another laptop running this kernel version, scangearmp can now detect the MG7150 Canon scanner over wifi. I don't know what's changed to fix this but you can now close this bug if you wish.

Canon have come back with: "Unfortunately you need to wait for scangearmp to update so that it then supports ubuntu version 14.04. We are not yet aware of a scheduled time of release for this update, the only thing I can recommend is that you keep an eye on the website to see when the scangear is updated to support this." And I notice now at the download link for scangearmp v2.20 it says under System Requirements: Fedora 18(32bit/64bit) Ubuntu 13.04(32bit/64bit) So, maybe when Canon update scangearmp to support 14.04 they'll take a look at this bug... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1529232 Title: Scanner not detected over wifi since after 3.13.0-68 Status in linux package in Ubuntu: Fix Released Bug description: Please see http://ubuntuforums.org/showthread.php?t=2306464 for details.

[Kernel-packages] [Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
Hi. Sorry, I just don't have the time to locate the commit that fixes the issue. My machine is old and slow, so even building the kernel once would probably take ages. Frankly, it would be less effort to boot into Windows every time I wanted to scan something! Ideally we could get Canon interested in finding the good commit and in testing each kernel build. I raised a support request yesterday and gave them the link to this bug. But I haven't got much meaningful back from them so far. They said this: "Thank you for providing Canon with your feedback regarding this particular issue when trying to scan with scangearmp with your Ubuntu 14.04 system. I can confirm that the scangearmp functions normally on an Ubuntu 13.04 system, however you will have to wait for the next update. For more information I would like to direct you to our download page. http://www.canon.co.uk/support/consumer_products/products/fax__multifunctionals/inkjet/pixma_mg_series/pixma_mg7150.aspx?type=drivers&driverdetailid=tcm:14-1094039&os=Linux%20(64-bit)&language=EN" - it's not clear to me by "you will have to wait for the next update" whether they are referring to an update of ubuntu or an update of scangearmp. I've asked them to clarify. I'll update this bug if they come back with any useful comments or suggestions. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1529232 Title: Scanner not detected over wifi since after 3.13.0-68 Status in linux package in Ubuntu: Fix Released Bug description: Please see http://ubuntuforums.org/showthread.php?t=2306464 for details.

[Kernel-packages] [Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
Lucas Patridge, I am closing this report because as per https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1529232/comments/23 the bug has been fixed in the latest development version of Ubuntu. This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, the next step is to fully reverse commit bisect from kernel 4.2 to 4.3 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting. After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed.

[Kernel-packages] [Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
Hi. I would prefer a backport to 14.04 if that's not to much trouble, please. I have no plans to upgrade to 16.04 until at least 6 months after it's released. Plus 14.04 is supposed to be supported for 5 years. Until this is fixed I have to boot into Windows or an older ubuntu kernel to use the scanner, which is obviously not very convenient. To be honest I'm surprised no other Canon scanner users of 14.04 have reported this issue. Maybe very few talk to the scanner over wifi. Do you have any idea what's caused the problem? All we seem to have established is that it's fixed in 16.04 and a recent kernel! This has worked, broken in the past, and then worked again before breaking yet again; so something keeps changing which breaks the wireless-detection functionality. Even if I waited for 16.04 I'm not reassured that it won't break again, given the chequered history of this issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1529232 Title: Scanner not detected over wifi since after 3.13.0-68 Status in linux package in Ubuntu: Incomplete Bug description: Please see http://ubuntuforums.org/showthread.php?t=2306464 for details.

[Kernel-packages] [Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
Ok, I tested xenial-desktop-i386.iso (sha1sum d066f5a8f8502c623501857b1464713be9940c79) from today's daily build. I put it on a USB stick and booted into it. (For my own notes: press F11 to enter boot menu on startup, then press Tab and 'live' to boot into live ubuntu.) I entered my wifi password then installed scangearmp from Canon's website (scangearmp-mg-7100series-2.20-1-deb). It *was* able to find my Canon scanner and perform a scan successfully. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1529232 Title: Scanner not detected over wifi since after 3.13.0-68 Status in linux package in Ubuntu: Incomplete Bug description: Please see http://ubuntuforums.org/showthread.php?t=2306464 for details.

[Kernel-packages] [Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
@penalvch: I've never tested an upstream kernel before so thanks for the instructions! I'm nervous about ruining my system, so please can you confirm my understanding is correct before I go ahead with this: 1) I've downloaded these files into their own folder: linux-headers-4.4.0-040400rc7_4.4.0-040400rc7.201512272230_all.deb linux-headers-4.4.0-040400rc7-generic_4.4.0-040400rc7.201512272230_amd64.deb linux-image-4.4.0-040400rc7-generic_4.4.0-040400rc7.201512272230_amd64.deb 2) If I run 'sudo dpkg -i *.deb' in that folder in a terminal I should get a new entry in my GRUB menu. 3) I can then attempt to boot into that kernel from GRUB at boot time (and run scangearmp to see if it detects the scanner). 4) If the OS fails to boot for whatever reason I can simply reboot my PC and choose my original kernel from GRUB (i.e., 3.13.0-74-generic). Is it true that my system will be unharmed so long as I don't boot into the upstream kernel? If you can't be 99-100% sure about this I'll have to buy an external drive and clone my drive to it; which will take some days...

[Kernel-packages] [Bug 1529232] Re: Scanner not detected over wifi since after 3.13.0-68
Lucas Partridge, at your earliest convenience, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.
