QIIME2 installation failed with filenames like 'q2-****-2020.2' cannot be downloaded

Hello everyone,
I’ve tried many times to install qiime2-2020.2 on my ubuntu according to the Natively installing QIIME 2 document, while every time it failes with the following messages, and I have found that almost every file that has a name like “q2-***-2020.2” cannot be downloaded, how could I solve this problem?

PS:
I have already shut my conda firewall, and change the mirrors using the following command:
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
conda config --add https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --set show_channel_urls yes

Hi @fengzhou -

The error messages are telling you that you are unable to download the QIIME 2 conda packages - which I think makes sense, given that you are adding in mirrors for other conda channels, like conda-forge. Are you able to use a local mirror of the qiime2 conda channel? We don't maintain or operate one, but please share if you know of one.

Thanks!

:qiime2:

HI @thermokarst

I had also tried many times before I change the mirrors, the error messages were just the same like that I put above.

I Google my question and I found people says change conda mirrors may be helpful, so I change my mirrors according to the author’s advice. However, I found it didn’t solve my problems any bit, It’s still all the same.

These mirrors are in my own country, and I think it should be the most fast and should not encounter any connection issues.What happen here?

I am in China, I don’t know which qiime2 conda mirror do you maintain, could you please telling me one?

Hi @fengzhou,

The mirrors you added appear to be working just fine, but, like I mentioned, you didn’t add a mirror for qiime2, so you are missing all of those packages.

I’m sorry, as I mentioned above, we don’t run or know of any qiime2 conda mirrors. You could possibly try a VPN service, but I don’t know what the legal status of a tool like that is in your country.
