**** BEGIN LOGGING AT Wed Aug 07 03:02:32 2019 Aug 07 15:21:49 Hello everyone, there's something wrong when i sudo apt-get update. Aug 07 15:22:29 it says:Temporary failure.....and Failed to fetch http://..... Aug 07 15:23:04 Some index files failed to download. They have been ignored, or old ones used instead. Aug 07 15:36:24 IVK: probably your beaglebone doesn't have an internet connection Aug 07 15:37:36 that would at least be my guess based on the tiny bits and pieces you've copy-pasted (the full output might give more clarity. but please don't paste multi-line stuff into chat, instead use a paste service like pastebin.com ) Aug 07 16:20:45 hi guys, when i connected my beaglebone black to my pc with usb, it can't update, but with router it works, anyone knows why? thanks Aug 07 16:21:23 because connecting the beaglebone to your pc via usb only gives your pc access to the beaglebone, but it does not grant internet access to your beaglebone Aug 07 16:21:36 please do not send private messages Aug 07 16:23:04 giving the beaglebone internet access when it is connected to your pc is possible in principle, but it can be a bit tricky to set up (it required sharing internet access from your pc to your beaglebone, and changing network settings on the beaglebone to make it able to use of it) Aug 07 16:23:23 clear, thanks mate Aug 07 17:25:01 https://pastebin.com/tQesWpv2 Aug 07 17:26:33 hello guys, the python-can can not be installed Aug 07 17:41:59 use pip3, not pip Aug 07 17:42:31 for backwards compatibility reasons, "python" is still a synonym for python2, and likewise "pip" is a synonym for pip2 Aug 07 17:42:38 also, don't be logged in as root Aug 07 17:42:40 and don't use sudo Aug 07 17:42:48 log in as normal user (debian) Aug 07 17:43:28 (likewise use "python3" instead of "python", since "python" is still the obsolete python2) Aug 07 17:44:54 "pip3 install python-can" while logged in as debian worked for me => https://pastebin.com/4bep6mHw Aug 07 17:44:55 thanks a lot! Aug 07 17:45:35 Hello Aug 07 17:48:02 Amitava: if you have a question you want to ask, just ask it (and have patience, it can take a while to get any response). don't expect any reply to "hello" Aug 07 17:48:58 Where can i order Beagleboard for AI Aug 07 17:50:58 this is not a sales channel. in case of the beaglebone-AI however there's an easy answer: nowhere yet, it's not yet released. https://beagleboard.org/ai has a form to subscribe to more information Aug 07 17:51:25 i use python to creat a can communication but it says no module named can Aug 07 17:51:45 https://pastebin.com/3pzTC9iJ Aug 07 17:52:24 here is the python code Aug 07 17:52:29 https://pastebin.com/Jtt444Tz Aug 07 17:52:40 IVK: it helps if you actually *read* what I say when you ask questions Aug 07 17:53:08 19:43 <@zmatt> (likewise use "python3" instead of "python", since "python" is still the obsolete python2) Aug 07 17:54:49 :') sorry man, python3 works! Aug 07 17:55:27 looks like your code is currently not quite python3-compatible but it probably requires only very minor modifications (e.g. use parentheses around the argument(s) of print) Aug 07 17:56:53 thanks for the helf man, i'm new with python:') Aug 07 17:58:07 yeah it's unfortunate that debian stretch still defaults to python2 even though it's obsolete Aug 07 18:00:59 (y) Aug 07 18:05:12 debian is currently working on removing python2 entirely Aug 07 18:16:29 cool, gonna use python3 since now Aug 07 18:23:09 good idea :) python2 has not been actively developed for many years now, and end-of-life maintenance will finally end as of 1 Jan 2020. dozens of important python projects/libraries have pledged to drop support for python2 this year or next year Aug 07 22:06:48 Good advice zmatt python 2 will not be updated as of January 2020 by the python people. Aug 07 22:33:26 I find I feel the same way about when qt4 was unceremoniously purged from software repositories. Aug 07 22:33:59 "updates stopped, Kill It With Fire ASAP!" Aug 07 22:34:10 "it never existed!" "hurrah! Aug 07 22:34:23 "erm, csuse me, I was *using* that?!" Aug 07 22:35:03 /soapbox Aug 07 23:12:13 lol Aug 07 23:12:23 veremitz: end-of-life for python2 has been known for a long time though Aug 07 23:14:31 and it has already been extended, the original planned EOL was 2015 Aug 07 23:14:41 it was moved to 2020 under pressure Aug 07 23:20:44 Honestly although it seemed like a long time, I would hazard to say the 10 years was about right for it. Most of what was python 2 has migrated to python 3 or was obsoleted. Aug 07 23:21:50 dunno, it might just have made people lazy about moving their code to python 3 Aug 07 23:22:32 regardless, I feel like the characterization veremitz just gave really doesn't apply in this case Aug 07 23:23:08 this wasn't sudden. the fact that python 2.7 would be the final major 2.x release was known since 2011 Aug 07 23:23:55 or at least officially published in a PEP in 2011 (PEP-0404) Aug 07 23:52:07 Many people procrastinate on things. However the advantage of such a long period of time with programmers is their projects are so short lived by comparison is most new things ended up started in python 3 because 2 was going out. That is my thinking anyhow. Most of the old stuff was maintained a while and anything that really was worth porting was. Aug 07 23:55:47 except the lack of urgency to move to python3 left python2 so pervasive that new users kept using it Aug 08 00:02:34 true enough, that I think was the linux distribution and installs for python fault. IE instead of using 3 (which their aren't many differences in truth) they tended to install 2 by default. Aug 08 00:03:18 anyway, it seems the end of this mess might finally be in sight :P Aug 08 00:03:57 until then I accept that I'll periodically have to tell people to use python3 instead of python2 **** ENDING LOGGING AT Thu Aug 08 02:59:57 2019
