hi
what is the problem?
( ubuntu 14.04)

robertferanec , 05-29-2021, 03:17 AM

Please, what is the version of your Ubuntu? Did you use the same version as I did? I see you are saying 14.04 - but the picture looks different from what I used.

I got tired.
I have neck pain!
but I never give up.

M. Namvar , 06-02-2021, 10:32 PM

I Fixed that.
1-Upgrade to ubuntu 14.04.7

then use this :
$sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt update
$ sudo apt install python3.6

robertferanec , 06-05-2021, 02:44 AM

@M. Namvar does it work now? I could try it, but I tried it couple of months ago and it was working. Maybe something has changed - if you can't figure out what the problem is, I will try to install it on my computer.

M. Namvar , 06-05-2021, 04:15 AM

@robertferanec Hi
I can not run Repo init because of the Python version and HTTPS SSL error.
I tried and tried to install the SSL package. no luck!
then I upgraded ubuntu to 14.04.7.
SSL problem solved but installing Python became my new problem.
after all the above methods worked.

M. Namvar , 06-06-2021, 06:16 AM

if you are behind a proxy server, like me, the repo sync may fail. So use these commands to solve it.

Setting the proxy for Git

1. Open a command prompt
2. Run the following commands replacing USERNAME, PASSWORD, PROXY_ADDRESS, and PROXY_PORT with your network's information:
   1. git config --global --add http.proxy http://USERNAME:PASSWORD@PROXY_ADDRESS:PROXY_PORT
   2. git config --global --add https.proxy http://USERNAME:PASSWORD@PROXY_ADDRESS:PROXY_PORT
3. Run the following commands to prevent SSH problems:
   1. git config --global url."https://".insteadOf git://
   2. git config --global url."https://github.com/".insteadOf git@github.com: (don't remove the final colon)
4. If your computer is within a corporate network that uses personal network drives, ensure identical copies of your .gitconfig file exist on both the network drive and your local drive's user profile (e.g. F:\ and C:\Users\USERNAME).

meta-fsl-arm-extraerror: Cannot fetch poky from https://git.yoctoproject.org/git/poky

robertferanec , 06-14-2021, 07:24 AM

I had a look into the git:


Maybe try:


Please let me know if that helped. Thank you

robertferanec , 06-16-2021, 12:16 AM

I will try to build it when I am at home.

PS: Maybe have a look into the manifest file and update link to poky?

robertferanec , 06-16-2021, 10:01 AM

I just tested it. Only what I had to do was update to python 3.6 ( exactly as you described in https://designhelp.fedevel.com/forum...7762#post17762 except pint 1) and then it just worked:



I have not seen any problems with HTTPS and anything else what you were describing in the other posts. After I installed python 3.6, it just worked.

Maybe it is something with your Ubuntu installation? Did you try to download the Ubuntu which I created? The link is under the lesson video in Links & Download TAB.

qdrives , 06-18-2021, 01:11 PM

Do not ask me about Yocto, but python 2.x and 3.x are not compatible to each other!

"Do not use Bitbake as root.", any ideas?

robertferanec , 07-01-2021, 01:05 AM

Please, where in the course you are? Which lesson and what minute?

M. Namvar , 08-01-2021, 11:14 PM

Hi Robert
Can you help me?
Yocto lesson 3

robertferanec , 08-02-2021, 02:34 AM

Please double check the changes you made ... maybe an error in the conf file? See the messages at the top of the screen.

M. Namvar , 08-04-2021, 11:44 PM

Related to the above explanation

M. Namvar , 08-07-2021, 01:45 AM

Hi again
there is no u-boot.imx in the git directory.
Where did I go wrong؟

robertferanec , 08-09-2021, 03:16 AM

Maybe try to have a look into u-boot-fslc directory ... maybe the uboot you are building has a different commit number?

M. Namvar , 08-09-2021, 08:42 PM

it is empty

M. Namvar , 08-09-2021, 08:49 PM

Ah, Solved!

Clement , 01-13-2022, 07:21 AM

I checked my network setting, it seems I didn't setup any proxy server. Is that mean i need to setup the proxy server before I can run the command,
"repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b jethro"?

robertferanec , 01-14-2022, 08:08 AM

@Clement please just confirm, you are behind a proxy, right?

robertferanec , 01-15-2022, 01:15 PM

@Clement I repeated all the steps from the course and now I passed the point where your installation failed, it is working oki in my virtual machine. I am not really sure why you are having the problems. Maybe try again ... everything I had to do extra was running the commands as @M. Navar described: $sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt update
$ sudo apt install python3.6

I had to run them because "repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b jethro" failed with error:
"repo: error: Python 2 is no longer supported; Please upgrade to Python 3.5+."

robertferanec , 01-15-2022, 02:09 PM

However, it looks like they have changed something again. When I run repo sync, I am getting errors like:
"fatal: unable to access 'https://git.yoctoproject.org/git/poky/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none"

I will check how to fix this problem. If you can't find the solution, please send me an email and I will return your payment.

robertferanec , 01-17-2022, 05:00 AM

@Clement I am still working on the certificate issue. I contacted Lubomir, he is an expert for YOCTO and he may be even doing another YOCTO course. He may be able to help with this. I will let you know when I have some updates.

Is there anything new on your side? Have you been able to move ahead?

robertferanec , 01-18-2022, 04:32 AM

@Clement I updated the Lesson 1 description, this should help:

Install the new version of Python
$sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt update
$ sudo apt install python3.6

Disable certificates
export GIT_SSL_NO_VERIFY=1

If you keep having problems with certificates:
sudo dpkg-reconfigure ca-certificates
sudo update-ca-certificates

Update curl
sudo nano /etc/apt/sources.list

Into sources.list insert
deb http://security.ubuntu.com/ubuntu xenial-security main
deb http://cz.archive.ubuntu.com/ubuntu xenial main universe

and then run
sudo apt-get update
sudo apt-get install curl

Let me know.

rutrilla , 01-20-2022, 12:03 PM

Hi all!

I've followed without problem all the instructions in the video of Lesson 1 up to minute 43:25. At which point I get the same error @robertferanec previously reported: "repo: error: Python 2 is no longer supported; Please upgrade to Python 3.5+."

However, I'm not able to install python3.6 following the above instructions (#29). Specifically, I run the first two commands with no problem. After that, the /etc/apt/sources.list.d/deadsnakes-ppa-trusty.list file is created with the following lines:

deb http://ppa.launchpad.net/deadsnakes/ppa/ubuntu trusty main
# deb-src http://ppa.launchpad.net/deadsnakes/ppa/ubuntu trusty main

But when I run the last command (sudo apt install python3.6) I get:

E: Unable to locate package python3.6
E: Couldn't find any package by regex 'python3.6'

I've also tried the instructions of "Disable certificates" and "Update curl", but got the same results.

I finally managed to install python3.6 by downloading and installing it manually, as explained in Method 2 on this website: http://devopspy.com/python/install-p...-6-ubuntu-lts/

After this, "repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b jethro" failed with error:

Downloading Repo source from https://gerrit.googlesource.com/git-repo
fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error unknown url type: https
fatal: cloning the git-repo repository failed, will remove '.repo/repo'

My repo version (repo --version) outputs:

<repo not installed>
repo launcher version 2.17
(from /home/rutrilla/bin/repo)
git 1.9.1
Python 3.6.3 (default, Jan 20 2022, 19:01:11)
[GCC 4.8.4]
OS Linux 4.2.0-42-generic (#49~14.04.1-Ubuntu SMP Wed Jun 29 20:22:11 UTC 2016)
CPU x86_64 (x86_64)
Bug reports: https://bugs.chromium.org/p/gerrit/i...epo+tool+issue

I've searched for this error (https://groups.google.com/g/android-...aPe4vP_8?pli=1) and I'm afraid the problem must come from python being built without the necessary features.

Does anyone have any idea how to unlock this situation?

Thanks in advance!

robertferanec , 01-20-2022, 12:18 PM

I am testing it again. What Ubuntu did you download? This one? http://old-releases.ubuntu.com/relea...ktop-amd64.iso

robertferanec , 01-20-2022, 03:59 PM

So, the problem with the python installation above is, that there is no openssl. I had to do this:

Install openssl:

$ wget http://www.openssl.org/source/openssl-1.0.2e.tar.gz
$ tar -xvzf openssl-1.0.2e.tar.gz
$ cd openssl-1.0.2e.tar.gz
$ sudo ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl
$ sudo make
$ sudo make install

Then install the python:
$ wget https://www.python.org/ftp/python/3....thon-3.6.3.tgz
$ tar -xvf Python-3.6.3.tgz
$ cd Python-3.6.3

Edit config, open
$nano Modules/Setup.dist

Search for "ssl" and uncomment and update:

_socket socketmodule.c

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:

SSL=/usr/local/openssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto

Then, save the file and run:

$ sudo ./configure
$ sudo make
$ sudo make install

To test python and ssl run python3 and write there import ssl, it should look like this:
fedevel@fedevel-VirtualBox:~/fsl-community-bsp/Python-3.6.3$ python3
Python 3.6.3 (default, Jan 20 2022, 23:45:09)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
>>>
fedevel@fedevel-VirtualBox:~/fsl-community-bsp/Python-3.6.3$

Then go back to to fsl-community-bsp directory and try again:
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b jethro

I hope this helps. Midnight, time to go to bed ....

rutrilla , 01-21-2022, 07:11 AM

Well, I reinstalled Ubuntu and follow all the instructions step-by-step.

I got the following problem with "$ wget http://www.openssl.org/source/openssl-1.0.2e.tar.gz", but I downloaded the file from Firefox as a workaround.



Then, I was able to properly install openssl and python3.6, but I still have problems with the repo init command.



I've tried the rest of your instructions and some others I've found googling the error (export PYTHONHTTPSVERIFY=0 and others), but no lucky...

robertferanec , 01-21-2022, 08:50 AM

After you have python working, try to re-run all these, that is what I did and it worked:

Disable certificates
export GIT_SSL_NO_VERIFY=1

If you keep having problems with certificates:
sudo dpkg-reconfigure ca-certificates
sudo update-ca-certificates

Update curl
sudo nano /etc/apt/sources.list

Into sources.list insert
deb http://security.ubuntu.com/ubuntu xenial-security main
deb http://cz.archive.ubuntu.com/ubuntu xenial main universe

and then run
sudo apt-get update
sudo apt-get install curl

PS: Here is a different way to go around the python problem (I have not tested it yet, but this should also work):
export GIT_SSL_NO_VERIFY=1
cd ~
mkdir ~/bin
git clone https://gerrit.googlesource.com/git-repo
cd git-repo
git checkout 27da4ddeb9159573e0207f71e4d9b3ae286b5275
cp repo ../bin
chmod a+x ~/bin/repo
PATH=${PATH}:~/bin

robertferanec , 01-21-2022, 10:32 AM

@rutrilla fantastic! Please keep me posted.
@Clement please let me know if it helped to you too. Thank you.
