Describe your issue

The deprecation warning for profile.d/mamba.sh suggests to call

mamba shell init -s posix

mamba/micromamba/etc/profile.d/mamba.sh.in

Line 12 in 26785a6

echo "WARNING: - rerun 'mamba shell init -s posix' to get the correct value"

However, this creates an error for me:

critical libmamba Support for other shells not yet implemented.

Maybe related - there seem to be two issues in the realized profile.d/mamba.sh file.

cat $MAMBA_ROOT_PREFIX/etc/profile.d/mamba.sh

...

if [ -z "" ]; then
    ...
fi

__mamba_setup="$("/home/mathause/.mambabase//mamba" shell hook --shell posix 2> /dev/null)"
...

1. ${MAMBA_ROOT_PREFIX} is missing (mabye because it was expanded at creation time?)
   

   mamba/micromamba/etc/profile.d/mamba.sh.in

   Line 5 in 26785a6

   if [ -z "${MAMBA_ROOT_PREFIX}" ]; then

2. bin is missing from the path. Is CMAKE_INSTALL_BINDIR not set?
   

   mamba/micromamba/etc/profile.d/mamba.sh.in

   Line 20 in 26785a6

   __mamba_setup="$("@CMAKE_INSTALL_PREFIX@/@CMAKE_INSTALL_BINDIR@/mamba" shell hook --shell posix 2> /dev/null)"

   So CMAKE_INSTALL_DIR is defined in setup.py but no CMAKE_INSTALL_BINDIR is set.
   

   mamba/libmambapy/setup.py

   Line 12 in 26785a6

   def CMAKE_INSTALL_DIR():

Ultimately this may all be irrelevant as the file will anyways be remove in v2.10.0. But it's a bit annoying in the meantime.

i don't think it is a "matter of being annoying" but rather a matter of anybody moving from mamba 1.5 -> 2.0 having a broken system.

We just hit this in the wild today and it was rather disruptive.

Trying to run the suggested mamba commands to run init

$ mamba
bash: /home/mark/miniforge3//mamba: No such file or directory

On my bash shell, when I successfully run

/home/mark/miniforge3/condabin/mamba shell init -s bash

I get the following, when restarting my shell.

Error unknown MAMBA_EXE: "", filename must be mamba or micromamba

Noticed same a few hours ago:
$ bash: /home/mansoor/miniforge3//mamba: No such file or directory

[hmaarrfk]

Ps our workaround was to use conda to install mamba 1.

Agreed. Updating from 2.0.5 to 2.0.7 this morning broke my mamba. I reinstalled it, and updating directly from 1.5 to 2.07 and had the same issues. I can update from 1.5 to 2.05 without issue, though.

I get the following, when restarting my shell.

Error unknown MAMBA_EXE: "", filename must be mamba or micromamba

I also see this every time a new terminal is opened. It's coming from

mamba/libmamba/data/mamba.sh

Line 67 in 26785a6

echo "Error unknown MAMBA_EXE: \"${MAMBA_EXE}\", filename must be mamba or micromamba" 1>&2

I think it happens because etc/profile.d/mamba.sh is executed before my .bashrc (where MAMBA_EXE is defined). This only happens since 2.0.6 (for me) but I cannot see a reason why that changed.
