can't install anything using conda, it hangs in solving environment #8051

Closed solegalli closed 1 year ago

solegalli commented 5 years ago

Hello,

I don't seem to be able to install anything using conda. It hangs in "solving environment".

I tried: conda install -c anaconda pip conda install conda-build conda update conda conda install c- anaconda pandas

The all make conda try and resolve the environment until it crashes.

conda config --show-sources

gives:

channels:

I used to have conda-forge there, but I removed it after reading some threads. Either with or without I have the same problems.

I have conda 4.5.2 on windows.

Can you please help?

Hi, I appear to be having the same issue. conda was working in early December and I have not updated it since.

Steps to reproduce

  1. conda install python
  2. obtain the following error message
(base) C:\Users\nmacr>conda install python
Solving environment: failed

I started having this problem today. To try to fix it, I uninstalled anaconda, and installed miniconda and am still getting the same error message as @NickMacro . E.g., when I try to update or install anything, I get the same error.

I am in Windows 10.

EricThomson commented 5 years ago

As suggested by @solegalli, I was able to fix it by removing the conda-forge channel. To see if you have conda-forge installed, you can open your configuration file in .condarc or just enter conda config --get channels at your conda prompt. I removed the conda-forge line from .condarc, and I'm no longer getting the error. You can also enter conda config --remove channels conda-forge to remove it.

Strangely, after removing the channel, I've added it back and the error has not returned.

Edit: Note I did uninstall anaconda yesterday before trying this today, so there is a chance that was important. But the error did not disappear until I removed the channel.

nickmacro commented 5 years ago

Removing the conda-forge channel appears to remove this behavior and it continues to work after add conda-forge.

The following steps worked to resolve the issue.

  1. conda config --remove channels conda-forge
  2. conda config --add channels conda-forge

No other changes were required to fix this on my system.

Thank you @EricThomson and @solegalli for figuring this out!

soapy1 commented 5 years ago

There were issues with repodata for conda-forge packages yesterday afternoon causing some of the errors above. The issue should be fixed now, so you should be able to install without issues using the conda-forge channel. @solegalli is this still an issue for you?

solegalli commented 5 years ago

My issue is not resolved by adding / removing the conda-forge channel. I will try re-installing anaconda.

ougx commented 5 years ago

It works for me today with conda-forge.

soapy1 commented 5 years ago

@solegalli I'll need a bit more information to get to the bottom of what's going on. Could you give me the output of conda info, as well as the command you are running that is broken and the output of that command.

solegalli commented 5 years ago

I tried: conda install -c anaconda pip conda install conda-build conda update conda conda install c- anaconda pandas

The output of any of this is python crashing. And the install aborting. The conda prompt does not close though.

dschreij commented 5 years ago

I also have this problem. Removing and readding conda-forge does not fix it, sadly. Any updates on the possible cause of this?

assumptionsoup commented 5 years ago

I'm having the same issue. I've reinstalled anaconda. I've removed the conda-forge. Attempting to update from command line conda update conda fails. Conda fails when trying to create any environment, or install any package. Effectively, conda is now completely broken for me.

assumptionsoup commented 5 years ago

Conda lists the following as my default channels:

  - https://repo.anaconda.com/pkgs/main
  - https://repo.anaconda.com/pkgs/free
  - https://repo.anaconda.com/pkgs/r
  - https://repo.anaconda.com/pkgs/pro
  - https://repo.anaconda.com/pkgs/msys2

Changing my .condarc from

channels:
  - conda-forge
  - defaults

to 

channels:
  - conda-forge
  - https://repo.anaconda.com/pkgs/main
  - https://repo.anaconda.com/pkgs/free
  - https://repo.anaconda.com/pkgs/r
  - https://repo.anaconda.com/pkgs/pro

To explicitly remove https://repo.anaconda.com/pkgs/msys2 appears to have fixed the problem for me. Thanks to @soapy1 for the hint!

Up until now, I had the same problem. Running conda update conda or conda install <packagename> my computer was unresponsive almost 1 hour and after that in the stage of solving environment conda was giving, solving environment: killed

I removed conda-forge and the problem solved. Works as expected. I use Linux mint.

In my case, I solved it by setting the variables of the PROXY environment Since Conda did not have internet access to update.

then run

conda update conda

OK, I save my life

I had the same issue and i solved it by copying the following channels in condarc and instead o f defaults. I'm not sure it's the best way but it worked

Reinstalling anaconda didn't help. But starting a new linux account and installing anaconda resolved the issue. So must be something local.

TheCrimsondev commented 4 years ago

I had the same issue when adding conda-forge channel and i fixed it by changing channel-priority to "flexible"

conda config --describe channel_priority conda config --set channel_priority flexible

After that conda update conda woked fine again. I hope it helps.

Efroymson commented 4 years ago

Tried: conda config --set channel_priority flexible

and got an error. It allowed me to send a message to the maintainers, so perhaps someone will see it.

I am just trying to install the bezier, or r-bezier package, and it fails repeatedly.

LinYunWen commented 4 years ago

I had the same problem. I don't know why and how. It just suddenly happened right after I used it as normal last day. I am unable to conda install anything even cannot do conda update conda. Every time it stops after Collecting package metadata and shows 

Collecting package metadata (current_repodata.json): failed

I search on the internet and find this conda install error. I check conda clean which is just to remove some unused packages and zip/tar files.

So, I try to do conda clean --all and remove all the files which are auto-recommend by conda . Now it works well after that.

den-run-ai commented 4 years ago

I found that my cache of conda packages was corrupt due to my mistake and the re-generation of cache/metadata takes about 1sec per package, so it was very slow and it appears as stalled.

josh-greaves commented 4 years ago

Made sure Anaconda was up to date, and not running in the background. This fixed the issue

javafalcon commented 4 years ago

As suggested by @solegalli, I was able to fix it by removing the conda-forge channel. To see if you have conda-forge installed, you can open your configuration file in .condarc or just enter conda config --get channels at your conda prompt. I removed the conda-forge line from .condarc, and I'm no longer getting the error. You can also enter conda config --remove channels conda-forge to remove it.

Strangely, after removing the channel, I've added it back and the error has not returned.

Edit: Note I did uninstall anaconda yesterday before trying this today, so there is a chance that was important. But the error did not disappear until I removed the channel.

Thank you. I fix my problem by your suggestion.

Thx. I tried conda clean -i, which fix my problem.

KrisThielemans commented 4 years ago

Same problem here on Windows. I've tried conda clean -i, conda clean -all, checked the channel-priority (which was already flexible), no luck. I don't have conda-forge channel, or any others really. conda config --show gives

  - https://repo.anaconda.com/pkgs/main
  - https://repo.anaconda.com/pkgs/r
  - https://repo.anaconda.com/pkgs/msys2

conda update -vvv conda gives me

Seems to have been an OpenSSL issue for me. Trying to use conda search was what gave it away; after installing OpenSSL, it didn't hang anymore.

how did u install openssl?

KrisThielemans commented 4 years ago

how did u install openssl?

Good question! The following hangs

> conda install -c anaconda openssl
Collecting package metadata (repodata.json): /
daddydrac commented 4 years ago

The solution is to update Conda to latest version, then create a Conda env (I know it sounds redundant) and lastly, run:

conda config --set ssl_verify False

You’ll be able to download whatever packages. At some point you may want to re-run as True to regain SSL/TLS verification.

It seems there's something wrong with tsinghua source. And My laptop can access the two resources normally( i.e. https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro/linux-64/current_repodata.json) I don't know what's wrong with the network of my lab's server. (and on that server, conda update conda can install a lot of packages and pip can also install packages, so the usual network should be normal)

At first I have the default authoritised channels and I tried to remove the conda-forge channels, but it doesn't work. And I used condo clean, but after that, I still cannot install the packages. Then I conda update conda, this can update my conda(it installed a lot of packages) but after that I still cannot install hicexplorer. So I checked tsinghua source website to see the newest update, and update my .condarc to

channels:

Then I still cannot install hicexplorer (404 error).

tsinghua source has got the license, right?

Tonyarey commented 4 years ago

I had the same problem. Removing conda-forge cannot solve mine. Thanks to this blog "https://www.jianshu.com/p/2bca744fcd82", I run "conda clean -i" and solved this.

KrisThielemans commented 4 years ago

I've installed latest Anaconda3. a first conda update conda went fine. Then stuck again.

conda clean -idoesn't help me. @joehoeller's trick (create env, activate,conda config --set ssl_verify False`) doesn't help either.

So, I cannot use conda at all.

One thing to note is that at least now a Ctrl-C does abort (with my previous anaconda2 installation I needed to kill conda with the task manager)

FrankwaP commented 4 years ago

After one year without problem, I had the same problem yesterday, with the message:

Solving environment: failed with repodata from current_repodata.json

I fixed it by following @EricThomson advice: removing conda-forge from the root .condarc (inside the user directory).

I haven't tried it but removing then adding it again likely works because it changes the channels priorities.
