Error when creating an env when non sudoer on Ubuntu: filesystem error: status: Permission denied [/etc/pki/tls/certs/ca-bundle.crt]

[arthursw]

I tried to create an environment on Ubuntu 22.04 (I am not sudoer):

$ micromamba create -n envName python==3.10.8 -y

And I got the following error:

conda-forge/noarch                                          Using cache
nodefaults/linux-64                                           No change
nodefaults/noarch                                             No change
critical libmamba Multiple errors occured:
    filesystem error: status: Permission denied [/etc/pki/tls/certs/ca-bundle.crt]

I installed micromamba the manual way:

curl -Ls https://micro.mamba.pm/api/micromamba/linux-64/latest | tar -xvj bin/micromamba
export MAMBA_ROOT_PREFIX=/my/prefix
eval "$(./bin/micromamba shell hook -s posix)"
micromamba config append channels conda-forge
micromamba config append channels nodefaults
micromamba config set channel_priority flexible

Is there something I missed? What can I do?
