can't install python

davidsi · 14 Apr 2020, 03:54

I'm trying to use python for the first time. I get "python not found" ... so I tried to install it using opkg with the following
python
python2
python3
python-lite
python2-lite
python-3lite

and in every case I get that the package can not be installed. I also tried opkg list and got nothing I could see that would help

Any help wold be greatly appreciated

@davidsi Has your Omega some active Internet connection?
opkg update
should be the first command before you can try to install anything.

@davidsi Did you edit /etc/opkg/distfeeds.conf and uncomment lines 2 and 5, then you can run opkg update. Then try opkg list | grep python to see a list of available python packages

@crispyoz Not needed to edit the /etc/opkg/distfeeds.conf file to install python-light, python or python3-light, python3 - the default distfeeds.conf is perfect.

# for example Omega2 with FW v0.3.2 b239
# the default src/gz omega2_packages http://repo.onioniot.com/omega2/packages/packages contains these packages too

# python-light - 2.7.17-1 - This package is essentially the python-base package plus a few of the rarely used (and big) libraries stripped out into separate packages.
# python - 2.7.17-1 - This package contains the (almost) full Python install. It's python-light + all other packages.

# python3-light - 3.6.10-1 - This package is essentially the python3-base package plus a few of the rarely used (and big) libraries stripped out into separate packages.
# python3 - 3.6.10-1 - This package contains the (almost) full Python install. It's python3-light + all other packages.

@György-Farkas or if you are having an issue with the onion repositories you can uncomment lines 2 and 5 and find the openwrt packages.

davidsi · 15 Apr 2020, 02:06

@György-Farkas yes and yes

davidsi · 15 Apr 2020, 02:08

@crispyoz Hmm, I already changed it for some other issue... right now I have

@davidsi what is the output if you type:

ping repo.onioniot.com
ping google.com

I wonder if you have either a DNS issue or a firewall issue.

György Farkas · 15 Apr 2020, 05:47

@davidsi Let's suppose I have some problem to install python3-light - so I need your help.
First of all I'd give you a few details about my system.

It seems I can reach the Onion Omega2 repos and I have enough room - so I try to install python3-light.

Success! On the Serial Console I can see everything.

davidsi · 16 Apr 2020, 02:24

@György-Farkas Sadly the same command did not work for me.

davidsi · 16 Apr 2020, 02:25

@crispyoz said in can't install python:

ping repo.onioniot.com

thanks, but no that was not it. I can see them both

crispyoz · 16 Apr 2020, 04:09

@davidsi can you post the output of your commands so we can see what is happening

György Farkas · 16 Apr 2020, 06:38

@davidsi Please let us know what is your device, what firmware are you using and the outputs of your commands.

Which one?
(I think your post is too informative - but only for you. Sadly. )

davidsi · 16 Apr 2020, 20:34

@crispyoz sadly no. I broke it last night. Apparently it does NOT like a 24V input ... sigh
