#linuxcnc-devel Calendar

01:33 AM pere: Tom_L: look like you configured using the wrong branch, ie for buster, not bookworm.
02:37 AM rmu: CaptHindsight[m]: no, not really, it depends, there is no overshoot at really low speeds (600mm/min and lower) and higher speeds (>5000mm/min) also work quite well, but in between, a large acceleration like when doing a 90° corner there is a bit of oscillation (2-3 cyles of +- 1 to 2 encoder counts) that i can't tune out.
03:02 AM pere: are there any plans to build linuxcnc for bullseye, ref my work on the live ISO. I skipped bullseye because there is no linuxcnc packages for it.
03:09 AM CaptHindsight[m]: pere: https://repository.qtpyvcp.com/repo/linuxcnc_debs/
03:10 AM pere: CaptHindsight[m]: thanks. how can you tell they are for bullseye?
03:14 AM CaptHindsight[m]: turboss built them when that po4a problem came up
03:15 AM CaptHindsight[m]: poke him if you want him to add Bullseye to the page info
04:24 AM -!- #linuxcnc-devel mode set to +v by ChanServ
04:36 AM Tom_L: pere, that was during the initial debian buster install i redid
05:01 AM pere: Tom_L: ack.
05:02 AM pere: Tom_L: note, the linuxcnc live build repo was moved and restructured last night.
05:25 AM pere: Tom_L: I suspect the bullseye version of live-build will work out of the box.

03:42 PM CaptHindsight[m]: pere: https://matrix-client.matrix.org/_matrix/media/r0/download/jauriarts.org/iiECMeZwixBzogRepQyGeFzW
03:42 PM pere: debian11 look promising. :)
03:43 PM pere: CaptHindsight[m]: do they also provide an APT source for them?
03:44 PM CaptHindsight[m]: sorry
03:46 PM pere: apt sources is easiest for live-build to handle. will have to look up how to handle local debs.
03:47 PM Tom_L: pere, GPG error: http://buildbot.linuxcnc.org buster InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EF1B07FEE0EE663EThe repository 'http://buildbot.linuxcnc.org buster InRelease' is not signed.
03:47 PM Tom_L: any way around that to access the repos
03:47 PM pere: nope.
03:47 PM CaptHindsight[m]: if only there was someone that managed this
03:47 PM pere: not that I am aware of.
03:47 PM Tom_L: i added the key and still didn't help
03:47 PM Tom_L: why were they moved?
03:48 PM pere: I suspect it need to be added inside the chroot, after it is created, and do not know how to do that.
03:48 PM Tom_L: it prevents me from installing linuxcnc in a way that your iso build won't fail
03:48 PM pere: Tom_L: are you building the buster iso?
03:48 PM pere: the bookworm build had these apt sources removed.
03:49 PM Tom_L: i'm not building anything yet. i installed buster again and trying to install linuxcnc on it
03:49 PM Tom_L: then i -was- going to build bookworm iso
03:49 PM pere: ah. then it is a different problem.
03:50 PM Tom_L: alot must have changed
03:50 PM pere: as http://buildbot.linuxcnc.org/dists/buster/InRelease is signed, apt-key add should be able to add the public key needed for apt update to accept it.
03:50 PM Tom_L: i tried that
03:51 PM pere: where did you find the public key for EF1B07FEE0EE663EThe ?
03:51 PM Tom_L: in the error message :)
03:51 PM pere: EF1B07FEE0EE663E, I mean.
03:51 PM pere: I mean the key file you fed to apt-key add.
03:52 PM Tom_L: i didn't have a file
03:52 PM Tom_L: one sec
03:52 PM pere: I see <URL: http://buildbot.linuxcnc.org/ > got a recipe.
03:52 PM -!- #linuxcnc-devel mode set to +v by ChanServ
03:53 PM Tom_dev: gpg --keyserver hkp://keyserver.ubuntu.com --recv-key EF1B07FEE0EE663E
03:53 PM Tom_dev: i did that
03:53 PM Tom_dev: but i dunno if that was the right thing
03:53 PM pere: look like this should do all of it: sudo apt-key adv --keyserver hkp://keys.openpgp.org --recv-key EF1B07FEE0EE663E
03:53 PM pere: the gpg command only update ~/.gnupg/, not the apt key store.
03:53 PM pere: jepler[m]: hi. :)
03:54 PM jepler[m]: hi, noticed matrix had kicked me out of the channel for inactivity
03:54 PM pere: jepler[m]: we have missed you a lot. :)
03:54 PM jepler[m]: but hi all
03:55 PM Tom_dev: gpg: key EF1B07FEE0EE663E: new key but contains no user ID - skipped
03:55 PM jepler[m]: thanks
03:55 PM pere: Tom_dev: from apt-key?
03:55 PM Tom_dev: yessir
03:55 PM Tom_dev: the line you just posted
03:57 PM pere: testing in a bookworm chroot, here it worked:
03:57 PM pere: # apt-key adv --keyserver hkp://keys.openpgp.org --recv-key EF1B07FEE0EE663E
03:57 PM pere: Executing: /tmp/apt-key-gpghome.gxrjH2Y0ys/gpg.1.sh --keyserver hkp://keys.openpgp.org --recv-key EF1B07FEE0EE663E

03:57 PM Tom_dev: W: GPG error: http://buildbot.linuxcnc.org buster InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EF1B07FEE0EE663E
03:58 PM Tom_dev: i'm very new to this
03:59 PM pere: Tom_dev: I am starting to believe you have very high bogon flux field around you.
03:59 PM Tom_dev: naw not me !
04:00 PM Tom_dev: i think it broke when the repos were moved or whatever happened in the last couple days
04:00 PM pere: the git repo? can not break the apt repo.
04:02 PM Tom_dev: i can still dl the debs i suppose but get an error due to the absence of gtksourceview2 or whatever it was called
04:03 PM pere: do 'apt-key list|grep LinuxCNC' show "uid [ unknown] LinuxCNC Buildbot <nomail@linuxcnc.org>"? Mine does.
04:03 PM pere: jepler[m]: any chance you got time to comment on or accept some pull requests today?
04:04 PM Tom_dev: apt-key output should not be parsed (stdout is not a terminal)
04:05 PM pere: yeah, that is a hint to not expect its output to be stable. safe to ignore.
04:06 PM Tom_dev: i don't see it there
04:07 PM pere: does it help to move ~/.gnupg out of the way, could it be messing with apt-key?
04:08 PM pere: I am intriged by the errors you can trigger that I can not.
04:08 PM Tom_dev: heh
04:08 PM Tom_dev: this is a fresh (as of this afternoon) buster install
04:09 PM pere: I'm building a buster chroot to test it myself. will take 15-20 minutes
04:09 PM pere: your gpg command created ~/.gnupg/ and added a key to it. my idea is that this confuses apt-key, and doing mv ~/.gnupg ~/.gnupg-dontuse or something like that might help
04:10 PM Tom_dev: way above my pay grade
04:12 PM pere: nah, it is not that well paid. :P
04:12 PM Tom_dev: same result with the old buildbot key
04:14 PM pere: what do you mean by the old buildbot key? Where do you see a new one. As far as I can tell, there is only one key
04:15 PM Tom_dev: 3cb9fd148f374fef
04:15 PM Tom_dev: that was the one we used with buildbot previously
04:16 PM pere: ok. not shown on <URL: http://buildbot.linuxcnc.org/ >, did not know about it.
04:16 PM Tom_dev: i got it from JT-Cave but not sure where it originated
04:16 PM pere: my test buster live-build run was able to use the apt repo from the buildbot, telling me it is properly signed, at least.
04:19 PM Tom_dev: i will just build it from source
04:20 PM Tom_dev: i was just wanting to test the iso build
04:25 PM Tom_dev: you must have removed the buster-live-build
04:25 PM pere: I did not, but it was renamed to linuxcnc-live-build
04:25 PM pere: and will soon contain build rules for both buster and bookworm.
04:26 PM Tom_dev: i'll wait til it gets sorted out
04:29 PM pere: Tom_dev: I get the same error on buster that you got when doing 'apt-key remove E0EE663E;apt-key adv --keyserver hkp://keys.openpgp.org --recv-key EF1B07FEE0EE663E'.
04:31 PM pere: Tom_dev: this one work: apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key EF1B07FEE0EE663E
04:32 PM pere: Tom_dev: I guess the key uploaded to hkp://keys.openpgp.org lack username, while the one on ubuntus keyserver got it...
04:32 PM Tom_dev: i've used ubuntu's before successfully
04:33 PM Tom_dev: that also worked here
04:33 PM Tom_dev: :)
04:33 PM pere: someone ( seb_kuzminsky ? ) should change the proposal on buildbot.linuxcnc.org...
04:34 PM pere: or I uploaded the ubuntu key to keys.opengpg.org, but the user ID did not make it there intact. perhaps they are filtering it out?
04:35 PM Tom_dev: ok i think that allowed the buster 2.8 sources
04:36 PM Tom_dev: yes, thank you
04:37 PM Tom_dev: gtksourceview2 is still a sore spot
04:37 PM Tom_dev: gmocapy and another gui use it
04:39 PM pere: have no idea what that story is about.
04:39 PM Tom_dev: not available in buster iirc
04:39 PM Tom_dev: and possibly stretch
04:40 PM pere: <URL: https://tracker.debian.org/pkg/gtksourceview2 >
04:41 PM pere: unmaintained library, removed from unstable yesterday.
04:42 PM pere: s/yesterday/last year/
04:53 PM pere: jepler[m]: is Mark Vandoesburg still around? I suspect he implemented the code failing in <URL: https://github.com/LinuxCNC/linuxcnc/pull/1869 >.
