Not working on Ubuntu 20.04

[josiahcoad]

Hi, I have the following config: Ubuntu 20.04 conda-bash-completion 1.5 conda 4.9.2

echo $BASH_VERSION -> 5.0.17(1)-release echo $SHELL -> /bin/bash

I ran >>conda install -c conda-forge conda-bash-completion from the base environment.

It is not working. (i.e. I tried conda in[TAB] and nothing happens.) Any suggestions? Thanks

Hi @josiahcoad. A couple of quick questions:

• Have you already run conda init bash?
• Did you start a new shell after installing?

[josiahcoad]

hi @tartansandal thanks for the quick reply. Yes to both of those! I even rebooted my computer!

[tartansandal]

No probs. :smile: Some more questions:

• What do you get when you run conda list bash-completion?
• Are you using miniconda or the full anaconda install?

[josiahcoad]

• bash-completion 2.10
• miniconda

[tartansandal]

OK. So with miniconda, some people prefer to disable the automatic activation of their base environment by setting auto_activate_base: false in their ~/.condarc file. Have you done this?

[josiahcoad]

I haven't. In fact, I don't have a ~/.condarc file.

[tartansandal]

Damn. That's all the easy solutions out of the way. As a simple sanity check (while I spin up a docker container with the new Ubuntu) could you run:

> CONDA_ROOT=~/anaconda3   # <- set to your Anaconda/Miniconda installation directory
> source $CONDA_ROOT/etc/profile.d/bash_completion.sh 

And see if that triggers conda completion in the same shell.

[josiahcoad]

Actually, it doesn't!

[tartansandal]

Hmm interesting.

I've just spun up a fresh ubuntu:focal container, installed the latest miniconda, installed conda-bash-completion and its dependencies into the base environment, started a fresh shell and completion works. So I think we can rule out the new Ubuntu as an issue :smile:.

The above sanity check failing is probably the key: Could you run:

> bash -vx  $CONDA_ROOT/etc/profile.d/bash_completion.sh 

and post the output as a code block (inside triple backticks)?

Cheers!

[josiahcoad]

Well, thanks for checking! I wonder if something is overriding the tab functionality??

> bash -vx  $CONDA_ROOT/etc/profile.d/bash_completion.sh 

# shellcheck shell=sh disable=SC1091,SC2039,SC2166

if [ "x${BASH_VERSION-}" != x -a "x${PS1-}" != x -a "x${CONDA_BASH_COMPLETION_LOADED-}" = x ]; then

    # Check for recent enough version of bash.
    if [ "${BASH_VERSINFO[0]}" -gt 4 ] || \
       [ "${BASH_VERSINFO[0]}" -eq 4 -a "${BASH_VERSINFO[1]}" -ge 1 ]; then
        [ -r "${XDG_CONFIG_HOME:-$HOME/.config}/bash_completion" ] && \
            . "${XDG_CONFIG_HOME:-$HOME/.config}/bash_completion"
        if shopt -q progcomp && [ -r /home/josiahcoad/miniconda3/share/bash-completion/bash_completion ]; then
            # Source completion code.
            . /home/josiahcoad/miniconda3/share/bash-completion/bash_completion
        fi
    fi

+ '[' 'x5.0.17(1)-release' '!=' x -a x '!=' x -a x = x ']'

[tartansandal]

Bingo! :partying_face:

Your interactive prompt PS1is not defined for some reason, so we skip loading completion functions since they won't be used.

Maybe something in your set up is undefining PS1? Perhaps some fancy prompt code? Some custom tweaks in your .bashrc or .bash_profile?

[tartansandal]

Actually, ignore my previous comment. I'm an idiot :crying_cat_face:.

Try running:

> bash -vxi  $CONDA_ROOT/etc/profile.d/bash_completion.sh 

and post the output as a code block. (I forgot to add the interactive -i to the bash command)

[tartansandal]

It occurs that this will be a lot of output. Just post the lines after <<< conda initialize <<< :smile:

[josiahcoad]

Oh haha np. I was pretty confused.

mmm are you sure? It's hundreds of lines of code...

[josiahcoad]

Got it.

[tartansandal]

Excellent! So the conda bash completion code is being loaded, but it's just not doing anything. Lets check the conda environment variables. Could you run:

> env | grep CONDA

and post the output in a code block?

[josiahcoad]

Thanks again for helping!!!

CONDA_EXE=/home/josiahcoad/miniconda3/bin/conda
CONDA_PREFIX=/home/josiahcoad/miniconda3
CONDA_PROMPT_MODIFIER=(base) 
_CE_CONDA=
CONDA_SHLVL=1
CONDA_PYTHON_EXE=/home/josiahcoad/miniconda3/bin/python
CONDA_DEFAULT_ENV=base

[tartansandal]

Not a problems :wink:

That env looks good. Now for some local variables:

> __comp_conda_ensure_root
> echo $CONDA_SOURCE

[josiahcoad]

/home/josiahcoad/miniconda3/lib/python3.8/site-packages/conda

[tartansandal]

Thanks for sticking with this. There are a lot of edge cases and variations in bash setups, so it's great to get detailed insight into end user environments and experiences. Also good to squash bugs. :smile:

That CONDA_SOURCE looks good.

Hmm one thing I've noticed with bash_completion in my Ubuntu container is that some times I have to hit <TAB> twice to trigger the completion. This happens with completing options for other commands than conda. I'm clutching at straws now, but could you try

> conda in<tab><tab>

[josiahcoad]

It works! I swear I smashed the tab a million times before lol so idk what changed.

[tartansandal]

He he. We still may have a problem, since we are in the 'sanity check' environment. Try a fresh shell or terminal before we start celebrating :smile:

[josiahcoad]

haha did this actually just to make sure. It seems like it is working!

[tartansandal]

That's great! Hope you enjoy the new completions. Back to watching the cricket :smile:

[josiahcoad]

Hahaha thanks so much. you really went above&beyond in support!
