Installation fails on Debian 10

[debian]

I am using Debian 10 and having some issues with Python/PIP.

I’ve managed to somehow stumble my way up to this point, after somehow finally installing virtualenv: pip install privacyidea

However, it fails to install the crypto dependencies, and I can’t proceed from here. This is the exact error at the end:

Building wheels for collected packages: cryptography, argon2-cffi, bcrypt

Failed to build cryptography argon2-cffi bcrypt
ERROR: Could not build wheels for cryptography, argon2-cffi, bcrypt which use PEP 517 and cannot be installed directly

I searched around and didn’t really get anywhere with this. Am I doing something wrong here?

Hi and welcome to the forum,
it looks like You don’t have a C-compiler (gcc) installed. Some Python packages require libraries which are compiled at install time.
Please check if the installation works after installing gcc.
Also according to the log You are using Python 2.7 which is deprecated. If possible switch to Python 3.

[debian]

OK, I think that helped. I installed GCC and found I already had Python 3, just needed to use python3 instead of python. With all that done, I started the process anew.

I think I’ve made progress, but I’m still getting a similar error here:

Failed to build cryptography
ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly
(privacyidea) root@mfa:/opt/privacyidea#

It has some successes after all the errors, but otherwise this appears to be what happened the other day. Are there any other build dependencies besides GCC? I don’t see any looking through the documentation.
Thanks!

[plettich]

Well, it is missing the openssl development package.
But usually it should not be necessary to build the packages, they should be available as wheels:

What Are Python Wheels and Why Should You Care? – Real Python

How do You install the virtual environment and privacyIDEA? Are You using an exotic OS or architecture?

[debian]

No, I’m running Debian 10 on a regular x86 machine as far as I know.

I installed PIP the regular way so it looks like I should have the wheel and not the system version (I did not specify --no-binary)

I installed virtualenv I believe by doing something like python3 -pip virtualenv [command] - it was something like that. I remember I had to specify pip before virtualenv or it would not work.

I’ve been following along using the links linked in the Privacy Idea documentation, using only the official recommended instructions. This seems to the best way, as I’m not using Ubuntu so there is no package available.

[plettich]

Here are the steps i did:

• install virtualenv:
  • apt-get install virtualenv python3-virtualenv
• create virtualenv:
  • virtualenv -p /usr/bin/python3 venv
• activate virtualenv:
  • . venv/bin/activate
• install stuff:
  • (venv) pip install cryptography

All packages installed as wheels:

Thank you! I tried following those exact steps, but I seem to be getting the same error.
Is it possible there are other dependencies for the cryptography package it won’t automatically install?

Typically Debian will install dependencies like that if desired but I’m not as familiar with PIP.
Thanks again!

Such errors usually indicate that you are missing the headers file, i.e. development packages.

[plettich]

@debian

Typically Debian will install dependencies like that if desired but I’m not as familiar with PIP.

basically PIP should do the same, it is a package manager for Python packages.
The issue here is that it is unable to download/install binary packages on Your system and thus wants to rebuild all the necessary Python extension (which fails because the required development packages are missing on the system).
Could You post the complete output of pip debug -v here to see which binary tags are compatible to Your system?

[debian]

Sorry for the delay, here is pip -v:

OK, I’ve made progress. Thank you!

For some reason, the wheel didn’t seem to do the trick. once I did apt-get install libssl I think it was, the pip cryptography install succeeded and the regular install succeeded too:

There is an error about it not being able to install the soupsieve packages for some reason. I can’t think what would be special there. But it seems like privacyidea itself was successfully installed and so I can try to proceed from here - or should I retry the installation until soupsieve also works? It seems like it didn’t get created:

[plettich]

First, the pip output is from the (default) Python 2.7. You should run the pip command in the activated Python 3 virtualenv.
Also it looks like You are running this on a 32 bit machine. The cryptography package only supplies wheels for 64 bit, so building the packages is the only option here.
The soupsieve package is needed for import/export of tokens via (XML) files. Maybe try re-installing it directly.

[Last_auth_standing]

i have a Running Cluster with Galery 4 on Debian 10. if there´s help needed with the set up i can help… it definitely works and is just a little bit more Work than on Ubuntu (you can even use the Ubuntu repository for Freeradius if you dont want to modify the files)

[debian]

Hey, thanks for the note!

Are you saying that if we used the Ubuntu repo, that would work as a drop in compatability package on Debian, with no other tweaks needed?
As in:

add-apt-repository ppa:privacyidea/privacyidea
apt-get install privacyidea

is all that would be needed?

I might decide to go that route then, assuming that’s stable.

Given the note about somehow having x86, and some IT upgrades that have been going on, I’ll be setting up a new server using a virtual machine rather than directly on bare metal. I’m partial to Debian 10 rather than clunky Ubuntu GUIs and from a server stability standpoint would prefer to go that route as well.

[cornelinux]

The ppa repo is deprecated. Use it, if you want to use old software!
Check the install chapter of the documentation at readthedocs!

“clunky Ubuntu GUIs”? Who on earth would install privacyIDEA on a Ubuntu desktop?
You wouldn’t install it on a Debian desktop, either?

~~

@Last_auth_standing said you could use privacyidea-radius (since this is only perl code). You can not use the privacyidea package. Might break a lot.
