nenadzi · 2018-11-29T17:33:05Z

Hi everyone,
I've already installed anaconda and start up anaconda prompt, but I cant start jupyter notebook in any way.
Also, I can't initiated anaconda navigator, anaconda prompt has recognised only
OS is W10.
Firewall is turn off.

Many thanks

I have no proper idea to suggest, but try updating the notebook with conda install notebook in the cmd prompt.

nenadzi · 2018-11-30T10:45:04Z

Hi Thomas

Hi Thomas
Thanks for suggestion, but unfortunately nothing happened.
I've tried the same instruction in the Anaconda Prompt, also

Yassica · 2018-12-06T22:55:34Z

Nenadzi, have you managed to solve this problem? I have the same problem with running jupyter notebook. I used to have all up and running, both anaconda 2 and anaconda 3 installed and then I have decided to re-install all and work only with anaconda 3 and now I can not make jupyter notebook work again . Log is bellow. Can somebody or you help? Thnx

pedjaziv · 2018-12-11T10:22:28Z

Ok, I have the exact message (except the user name part)... I've tried what you've suggested over here, but nothing helped :(

Is anyone found solution by now?

Thank in advance

PaleNeutron · 2019-01-21T04:46:16Z

@pedjaziv , look into my comment here.

@pedjaziv
I manage to solve this problem by removing the:
if certs: self.load_verify_locations(cadata=certs)
from file "C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\lib\ssl.py", lines 470 and 471

Thanks @r4m0 . This actually solved my problem.
I can verify that this problem is caused with certs from Serbian authorities.

Nicknames of people having a same problem indicates that this was an issue related to Balkan region, and now I'm 100% positive that those certs was a problem, because I had same problem on two machines where I have installed mentioned certs, and I had no issues on the other ones....

So once again, thank you and I want to thank @PaleNeutron also. I assume his method also works, but at the moment I need to keep those certs and cannot delete them.

Kind regards,
Pedja

r4m0 · 2019-02-18T12:16:20Z

I can verify that this problem is caused with certs from Serbian authorities.

@pedjaziv Exactly. I am from Serbia, Belgrade. I also did not want to delete those certs, so at the moment this was the only acceptable solution for me.

if certs: self.load_verify_locations(cadata=certs)
from file "C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\lib\ssl.py", lines 470 and 471

Hi @r4m0 @pedjaziv ,
I wasn't completely comfortable by removing completely the complete verification, so I added line at line 467:
if "MUP Republike Srbije" not in str(cert):
basically I instructed the function to ignore the certificates issued my MUP Rebuplike Srbije.

Now my _load_windows_store_certs function looks like this now (lines 460-473):
file: "C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\lib\ssl.py"
`

def _load_windows_store_certs(self, storename, purpose):
    certs = bytearray()
    try:
        for cert, encoding, trust in enum_certificates(storename):
            # CA certs are never PKCS#7 encoded
            if encoding == "x509_asn":
                if trust is True or purpose.oid in trust:
                    if "MUP Republike Srbije" not in str(cert): 
                        certs.extend(cert)
    except PermissionError:
        warnings.warn("unable to enumerate Windows certificate store")
    if certs:
        self.load_verify_locations(cadata=certs)
    return certs`

But then again, I am not really an expert in this, and I didn't know much about ssl or CA before this, so I would welcome any feedback on what I did here, and what impact it could have.

Thanks,
Boris

Thanks Boris !
Your ssl.py mod works. Craziest python error I ran into so far :)

rupurut · 2019-08-28T11:24:54Z

Hi,
I had the same issue and I solved it by uninstalling "Čitač elektronske lične karte" from Windows 10. :)
I was inspired with your answers and remember what was the last app I installed from MUP and that was it :) Thanks.

priyaranjan-tokachichu · 2019-10-21T03:30:35Z

I had the same issue. Copying the following dlls (libcrypto-1_1-x64.dll, libssl-1_1-x64.dll) from C:\ProgramData\Anaconda3\Library\bin to C:\ProgramData\Anaconda3\DLLs solved my issue. This is on Windows 10 with Anaconda3 64-bit.

This issue has been mentioned on Jupyter Community Forum. There might be relevant details there:

Hi @vera942,

The error seems like a general issue when handling the file for reading or writing. The file is locked for some reason and that may be causing an issue. I might recommend completely uninstalling Anaconda and then reinstalling it somewhere other then C:\Users\Vera\anaconda3, even maybe on some other drive. If that doesn't solve the issue, there may be some other issue with your system.

vera942 · 2020-09-20T20:28:31Z

i solved it. reinstall the OS. thanks anyway :) Vera Dimitrievska https://www.kaggle.com/vdimitrievska/notebooks https://github.com/vera942?tab=repositories www.verevere.wordpress.com T in NL: +31644801757 T in MKD: + 389 77 503699 skype name:veravera942

So far, deleting
if cert:
self.load_verify_locations(cadata=certs)
solved my problem.
On the other hand, adding up
if "MUP Republike Srbije" not in str(cert):
did not work for me

Alexander-Serov · 2021-10-13T10:00:38Z

If someone has solved this problem (after package update, very annoying), could you please share your fix?

Iz looks to me the same issue people are facing in Serbia and some other countries due to issue with SSL certificates. I followed instructions for some "solutions" with no result. Finally, I had to install jupyter on the computer without SSL certificates.

#4245 (comment)

Couldn't be more precise from this. This actually solved my problem without deleting certs.

goranad77 · 2021-10-14T09:46:22Z

Deleting
if cert:
self.load_verify_locations(cadata=certs)
solved my problem for short period of time. The problem occurred again and I changed PC. Can not be more precise. It happened a year ago.

vedraan · 2022-04-03T19:28:44Z

For Anaconda3-2021.11 and Serbian "MUP Republike Srbije" cert this issue can be solved by editing anaconda3\Lib\ssl.py just below this line (561 in current anaconda version, but best use search):

                    if trust is True or purpose.oid in trust:

add one additional line below it, so it looks like this:

                    if trust is True or purpose.oid in trust:
                        if "MUP Republike Srbije" not in str(cert):
                            certs.extend(cert)

This pretty much fixed it for me, all credits go to: https://algora.petlja.org/t/python-instalacija-windows/999/8

i encounted the same problem on lauching pyspider in conda 23.5.2 on Win10. Removing ssl.py line 588 and 589 true works for me. Besides i've tried to add a certificate by "conda install certifi" and give its path to ssl_verify, however it doesn't work.

vesnahrnjaksivcev · 2024-10-04T02:46:01Z

Posle više dana, rešenje je bilo sledeće: uninstalirala sam čitač elektronske karte sa računara i automatski sam ponovo pokrenula Jupyter iz Anaconde. Ne mogu da verujem da je čitač pravio problem.

DLumi · 2024-12-16T08:47:29Z

Just to add to what @BorisStricky have advised:
If you happen to use ASSECO 24x7 banking app, then you need to exclude those certificates as well, cause they seem to have the same issue.

if "24x7.co.yu" not in str(cert):
