undefined symbol: curl_url_cleanup

[THZ34]

An error has happened after I running 'conda update --all'
$mamba
Traceback (most recent call last):
File "/software/anaconda3/bin/mamba", line 7, in

[wolfv]

can you show a conda list and what channels you use?

[wolfv]

specifically what version of curl do you have now?

[THZ34]

Thank you for your reply, the following is the information about mamba and curl.
mamba 0.7.1 py38hc157fb9_0 https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge
curl 7.26.0 1 https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free

[wolfv]

That should really not be possible since mamba requires a version of libcurl >=7.71 ... How did you install mamba?
Also, it's advised to not mix packages from anaconda-default channel and conda-forge like this.

Ok, I will update my curl, thanks again.
