Errors during transaction when installing QIIME2-2019.10

Technical Support
1

Hi, I was trying to install the QIIME2-2019.10 by updating my conda environment first.
Running conda update conda however produced an error saying:

The environment is inconsistent, please check the package plan carefully
The following packages are causing the inconsistency:
(A long list of packages, mostly R packages installed via the conda-forge)

I tried many solutions to solve the problem including reinstalling (conda install package.name) and removing (conda remove package.name) the listed packages causing the inconsistency, neither helped though. Finally, I decided to reinstall my miniconda3 and try again. All the packages needed for the QIIME2-2019.10 were successfully installed. However, I encountered new errors again close to the end of installing QIIME2-2019.10 environment, which said:

Hi!
Did you try to run installation command in the terminal again without deleting unsuccessful installation?
I don’t know the issue of this problem but for several latest releases of Qiime2 I wasn’t able to install it without the errors from the first attempt but after repeating without deleting of failed environment it worked fine for me.
I reinstalled anaconda but encountered those errors anyway.

Hi, thanks for the suggestion! I tried the installation again without removing the failed environment but conda doesn’t allow that:

CondaValueError: prefix already exists: /home/nutrition_group/miniconda3/envs/qiime2-2019.10

Hi @yanxianl,

Try

conda remove --name qiime2-2019.10 --all

to remove the environment and then re-install.

Best,
Justine

Hi Justine, I tried your suggested command and it returned an error:

Remove all packages in environment /home/nutrition_group/miniconda3/envs/qiime2-2019.10:
PackagesNotFoundError: The following packages are missing from the target environment: -

The QIIME2 installation guides didn’t help either:

If you receive errors during the installation process, such as gfortran errors, please ensure you are following the installation instructions that are compatible with your platform. Other errors are often resolved by running conda env remove -n qiime2-2019.10 to remove the failed environments, then running conda clean -y --all to clean the local conda installation, and finally re-running the installation instructions above.

6

Sorry for my stupid question - did you restart your computer after miniconda/anaconda installation and before trying to install Qiime2?

7

Just tried restarting the PC before and after installing the miniconda, and tried to install qiime2-2019.10 again. Still, no luck though. Thanks!

Hey @yanxianl,

Based on the first error message, it looks like something went wrong with the TLS handshake, sometimes that’s because a server is misconfigured, your OS isn’t up to date, or there’s a firewall preventing access.

The three URLS being downloaded seem to be coming from different hosts (mostly)

So my guess is it’s a firewall situation. Are you able to click and download those links manually, and do you see anything like a redirect when you do so?

That test doesn’t help us install anything, but it’ll help us figure out the network situation.

Hello,

I am trying to natively install qiime2-2019.7 on my Mac OS High Sierra. I ran the command below:

conda env create -n qiime2-2019.7 --file qiime2-2019.7-py36-osx-conda.yml

The error message I keep getting is as follows

conda env create -n qiime2-2019.7 --file qiime2-2019.7-py36-osx-conda.yml

I have tried deleting and installing miniconda multiple times as well as deleting and downloading the qiime2-2019.7-py36-osx-conda.yml file multiple times to no avail. I have also tried downloading the file not being downloaded and unpacking that by hand, but that does not work either.

Any suggestions would be greatly appreciated!

Thank you.

Hey @ylor,

I believe @yanxianl is having an identical issue right now, so I’m going to merge this thread into that one (noting that your QIIME 2 version is 2019.7 instead of .10)

13

So we have two examples of this error now. It appears that @ylor is able to download those files manually, which suggests it may not be strictly a network problem.

Summarizing some observations:

@ylor is on OS X High Sierra
@yanxianl appears to be on Linux of some variety

The error isn’t the post-link like I thought at first, it’s the source that it can’t find.

Slightly different TLS errors:

Both are from curl, which might be stale (I don’t know if conda uses curl or libcurl directly).

14

Hi Evan, I’m using ubuntu 14.04. I was able to download the first and third package manually by clicking on the links in the terminal. The link of the second package, however, returned a 404 Not Found error.

Based on your suggestion that this could be a firewall problem, I turned off the firewall by running sudo ufw disable and tried installing qiime2-2019.10 again but I got the same error message.

15

Hi all,

I missed yanxianl’s post when I was searching the forum. Thank you for pointing it out, Evan.

I did get an error with the wget command to manually download the .yml file. I was able to download the .yml file by using the --no-check-certificate suggestion and by downloading the .yml file directly by clicking the link provided in the qiime2 docs for if an error is encountered with wget. See below for my wget error.

How would I resolve this source issue? When I look in my ./miniconda3/pkgs/, the bioconductor-genomeinfodbdata-1.2.0-r351_0.tar.bz2 file does exist and is unpacked already, so how can it not find the source?

Thanks.

Hello,

I totally got the same problem with yanxianl. Mine is also Ubuntu 14.04.
Is there any chance to this 2019.10 release can cause the trouble in Ubuntu 14.04?

Thanks for the additional details everyone!

Right now I am thinking this is a client-side issue with certificates. Since @yanxianl and @junkim83 are on Ubuntu 14.04 this isn’t very surprising. Cryptography on the web doesn’t move as fast as some things, but it does tend to improve year over year, so a five year old distribution of Ubuntu is probably missing some things that allow it to complete the TLS handshake. Is updating to Ubuntu 18.04 an option? That is the currently support LTS release.

I suspect @ylor’s situation is somewhat similar in that, while their OS X should be plenty up to date, likely the version of curl being used is stale and/or not looking in the right place in OS X. @ylor, what does:

which curl

tell you?

Hi Evan,

I was wondering about whether it had something to do with the curl version I was currently using also…

which curl gives me /usr/bin/curl

If you’re interested in the specific curl version:
curl -V

curl 7.54.0 (x86_64-apple-darwin17.0) libcurl/7.54.0 LibreSSL/2.0.20 zlib/1.2.11 nghttp2/1.24.0

Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp

Features: AsynchDNS IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz HTTP2 UnixSockets HTTPS-proxy

Hi Evan, upgrading the Ubuntu to 18.04 is not an option at the moment. We’ll have to do that months later. Do you think using an older version of miniconda allows for installation of previous qiime2 version, say qiime2-2019.7?

A quick update: I was able to install and run qiime2-2019.4. Installing newer versions, qiime2-2019.7 and qiime2-2019.10 threw the same error that I posted. For now, I’ll stick with qiime2-2019.4 and update the ubuntu to 18.04 later.
