**** BEGIN LOGGING AT Sun Jul 28 02:59:57 2019 Jul 28 08:37:33 i currently have this kernel 4.15.0-1031-raspi2 , how can i upgrade to https://launchpad.net/ubuntu/+source/linux-raspi2/4.15.0-1041.44 Jul 28 09:05:16 waheedi, "sudo apt update; sudo apt upgrade" should bring it in Jul 28 09:05:28 it didn't Jul 28 09:05:40 ogra: i even tried dist-upgrade Jul 28 09:05:47 everything is up to date Jul 28 09:06:10 not true :) Jul 28 09:06:48 try full-upgrade (though normally upgrade should be sufficient , check if you have security and updates enabled in your /etc/apt/sources.list) Jul 28 09:10:58 yes ogra, enabled Jul 28 09:11:03 I will try full-upgrade Jul 28 09:11:23 same Jul 28 09:12:03 what kernel is installed ? Jul 28 09:13:21 4.15.0-1031-raspi2 Jul 28 09:20:14 and thats a regular armh 18.04 install ?

Jul 28 09:21:41 (in your sources.list) Jul 28 11:29:42 thanks ogra: I do have them in my apt sources Jul 28 11:29:56 its not armhf its arm64 Jul 28 11:35:13 ogra: could this be the reason i don't see it ? sudo apt remove flash-kernel initramfs-tools Jul 28 11:40:41 waheedi: what's the name of the kernel pakcga eyou have installed exactly? dpkg -l | grep ^i...linux-image' Jul 28 11:40:54 waheedi: what's the name of the kernel pakcga eyou have installed exactly? dpkg -l | grep '^i...linux-image' Jul 28 11:41:04 ^typo fixed Jul 28 11:41:18 u can remove the quotes :) Jul 28 11:41:26 linux-image-4.15.0-1031-raspi2 Jul 28 11:41:30 yes, but not have a single only Jul 28 11:41:34 sure Jul 28 11:41:35 :) Jul 28 11:41:47 yeah i do have 4.15.0-1041.44 Jul 28 11:41:55 4.15.0.1041.39 Jul 28 11:42:30 do you have linux-image-raspi2 installed? Jul 28 11:43:03 yes Jul 28 11:43:06 both ii Jul 28 11:43:36 but why name -a still shows i: linux-image-4.15.0-1031 Jul 28 11:43:58 uname* Jul 28 11:44:14 right, linux-image-raspi2 is version 4.15.0.1041.39 for arm64 and depends onlinux-image-4.15.0-1041-raspi2 https://packages.ubuntu.com/bionic-updates/linux-image-raspi2 Jul 28 11:44:57 you will need to reboot, and ensure your boot loader will load the newer kernel image Jul 28 11:45:09 i did reboot and hard shutdown too Jul 28 11:45:21 i'm not sure which boot loader arm32 uses Jul 28 11:45:26 *arm64 Jul 28 11:45:58 is it gummiboot or something? Jul 28 11:47:51 U-Boot apparently Jul 28 11:48:02 in my config.txt i see kernel=kernel8.bin Jul 28 11:48:59 i'm afraid i know nothing at all about how arm64 boots really, nor what this config.txt is or where it is located, or how it is used. Jul 28 11:50:11 thanks tomreyn Jul 28 11:50:16 i appreciate the help :) Jul 28 11:50:21 using arm64 on a Pi is quite a waste (64bit arm binaries allocate 64bit registers in ram but will only use 32bit variables in it ... you just waste ram that way for o benefit) Jul 28 11:52:09 apparently "flash-kernel" is the equivalent to update-grub / grub-install on arm64. Jul 28 11:52:20 ... arm64 makes only sense if you actually have more than 4GB ... these pi images we offer on cdimage are great for develping arm64 stuff for big iron machines ... but thats about it Jul 28 11:52:44 yes, flash-kernel should set up u-boot to actually pick the right kernel after install Jul 28 11:52:58 https://help.ubuntu.com/lts/installation-guide/arm64/ch06s03.html#di-make-bootable Jul 28 11:53:41 waheedi: see above Jul 28 11:54:48 note that the postinst of the linux-raspi2 package calls flash kernel, so it should be all set-up Jul 28 11:55:12 (additionally the installer calls it too during installation) Jul 28 11:55:56 thanks ogra Jul 28 11:56:18 well, i just stated what "should" happen ... :) Jul 28 11:56:24 seems it doesnt or you for some reason Jul 28 11:58:14 i sadly havent touched the classic preinstalled images in ages (i' maintaining ubuntu-core for the pi though, but that boots fron snap packages and does not use flash-kernel) Jul 28 12:00:23 typically the proprietary botloader would load u-boot which then in turn loads your kernel and initrd based on uEnv.txt ... uEnv.txt should be the file flash-kernel modifies to point to a new kernel binary Jul 28 12:00:45 can you "ls -al /boot" and post that to paste.ubuntu.com ? Jul 28 12:01:24 (or is it /boot/ubot on classic ? i forgot ... the one that does contain the start.elf file and friends) Jul 28 12:14:24 you can install the pastebinit package and pipe into it if you dont use a serial console you can copy/paste from Jul 28 19:35:46 ogra: thanks, a lot Jul 28 19:35:56 I managed to manually upgrade the kernel Jul 28 19:36:07 now name -a shows 4.15.0.1041 Jul 28 19:36:10 uname* Jul 28 19:45:33 I'm going through this bluetooth notes :) https://bugs.launchpad.net/snappy/+bug/1674509 Jul 28 19:45:45 ogra: thanks a lot for that too :) Jul 28 19:48:00 im surprised i still see this "Cannot open directory '/etc/firmware': No such file or directory" **** ENDING LOGGING AT Mon Jul 29 03:00:13 2019
