sigh....Python3 upgrade - curl problem?
Dariusz Piatkowski:
So this whole 'upgrade to python3' is by now a well traversed path, I did my reading, took to the CLI approach of executing: 'yum install python3 python2.7', which gave me the following results:
--- Code: ---[G:\]yum install python3 python2.7

Therefore, my next logical (and maybe this was a mistake???) step was to upgrade all the pythonx stuff to python3, which I went to ANPM for:
1) python3-dateutil - this seems to have gone fine

Sure enough, ANPM is no longer able to pull anything up, reports a pipe error, although from CLI I get the following:
--- Code: ---[G:\]yum list python* |less
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named pycurl
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.18 (default, Dec 27 2021, 15:11:56)
[GCC 9.2.0 20190812 (OS/2 RPM build 9.2.0-5.oc00)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
--- End code ---
So it would appear that installing python3-pycurl obsoleted python-pycurl (which I would have expected is the correct thing to do), but for some reason ANPM continues to see python 2.7.18 as the version it is executing.
From any CLI when checking for the installed Python3 version I get the following:
--- Code: ---[G:\]python --version
Python 3.9.17
--- End code ---
...so clearly I'm running Python3, but ANPM is still using 2.7.18, is that by design?
Either way, any ideas how I can get back to a working YUM/RPM/ANPM config?...and what (if anything) do I do about the remaining pythonx RPM packages (do I upgrade, or leave alone)?
OH, BTW: a system reboot was executed to rule out any other impacts, results are the same
Dave Yeo:
Hmm, I never forced any Python upgrades besides the python2.7/python3 one and see I have python2-pycurl and python3-pycurl installed. Lots of things are python2 including ANPM.
If yum itself works, install python2-curl or perhaps download the zip and install the 8 files manually to get ANPM working then install the package.
JTA:
From the perspective of a new install of ArcaOS, there seems to be a difficulty in applying ALL outstanding ANPM updates at once, as the python issue pops up (2.x and 3.x aren't in place all the way yet?).
There are supposedly help articles on AN support pages to get you around this, but I just basically did a few specific updates by hand (in ANPM), and got it going again. IIRC, it was something like:
- update only the base 2.x python
- then update only the base 3.x python
Can't quite remember which one of the two I did first, but I think the trick was doing them separately ... after getting both of those to succeed, the last step is a mass ANPM update of anything else remaining, which also then worked for me.
I just stumbled through that, so didn't document each and every step, and assumed that what was on AN's support pages was a much better write-up.
Hope this helps ...

I wish I know more about python, like understanding more on how to run scripts.
I had an issue with ANPM on a recently installed copy of ArcaOS 5.1 that ANPM will not run an update all and will stuck on python. Error: "0003523: Can not update to python 3"
To fix the problem was basically:
- In ANPM went to "Available - RPM"
- Select"python2.7", "python3", "python-unversioned-command" and run "Install".
This is a package issue rather than an ANPM issue (the same problem occurs at the command line) according to what Lewis told me on the ticket.

Hi Dave,
Thanks for the quick response.
--- Quote from: Dave Yeo on December 10, 2023, 07:05:28 pm ---Hmm, I never forced any Python upgrades besides the python2.7/python3 one and see I have python2-pycurl and python3-pycurl installed. Lots of things are python2 including ANPM.

--- End quote ---
Alright...so I continued to troubleshoot the issue in the meantime, as in reviewing the scripts ANPM uses and concluded that it's a Python2 dependent implementation.
Therefore, precisely as you pointed out it made sense to bring back the pycurl RPM in order for the current YUM/ANPM to get back into working status.
To that end, I now see the following:
--- Code: ---[G:\]rpm -i /test/python-pycurl-7.19.5.1-2.oc00.pentium4.rpm
error: Failed dependencies:
python-pycurl < 7.44.1-3.oc00 is obsoleted by (installed) python3-pycurl-7.44.1-3.oc00.pentium4
--- End code ---
...clearly the python-pycurl and python3-pycurl are incompatible with each other, and in hindsight it seems like I should NOT have attempted to upgrade anything beyond just the core Python itself (at which point in time this becomes a little nonsensical / counterintuitive, after all, if the Python runtime is now at 3.x and if I happen to be using other python utils, shouldn't I be updating them all to make sure I am using the matching python stuff???).
Anyways, OK, so it looks like I'm going to force RPM to install python-pycurl regardless:
--- Code: ---[G:\]rpm -ivh --nodeps /test/python-pycurl-7.19.5.1-2.oc00.pentium4.rpm
Preparing... ################################# [100%]
Updating / installing...

--- End code ---
Yup, all good now: YUM at CLI works, as does ANPM.
