Hi Guys,

I vaguely recall that barman would work properly with bash auto-complete when I'd installed it some time ago on another system.

I've just recently installed it again and have found that bash auto-complete isn't working, is there something I can check/configure to ensure that this works?

Cheers.

I've just tested this on a rocky8 system and auto-complete works fine. What is it that doesn't work? Which OS/distribution are you using? How did you install Barman?

Hi @martinmarques,

It’s a Ubuntu build (22.04 I believe, I’ll need to check tomorrow when I am in the office). I used apt to install Barman 3.12.1.

Is there a bash auto complete file that I can drop into /etc/autocomplete.d/ or something to get this working? Curious if your rocky8 installation has an autocomplete file somewhere too?

Thanks

$ rpm -ql barman
/etc/barman.conf
/etc/barman.d
/etc/barman.d/passive-server.conf-template
/etc/barman.d/ssh-server.conf-template
/etc/barman.d/streaming-server.conf-template
/etc/bash_completion.d
/etc/bash_completion.d/barman
/etc/cron.d/barman
/etc/logrotate.d/barman
. . .

The bash_completion comes from here: https://github.com/EnterpriseDB/barman/blob/master/scripts/barman.bash_completion

I think you need to debug this in your system, and if there's a problem with the bash_completion on ubuntu, report it to the packagers (I suppose that would be PGDG)

Hi @martinmarques, please see below:

$ dpkg-query -L barman | grep completion
/usr/share/bash-completion
/usr/share/bash-completion/completions
/usr/share/bash-completion/completions/barman

I worked out the issue in our environment, funnily enough it was that we were missing the python3-argcomplete package.

The contents of the /usr/share/bash-completion/completions/barman file is:

eval "$((register-python-argcomplete3 barman || register-python-argcomplete barman) 2>/dev/null)"

Running the first portion interactively showed the following:

$ register-python-argcomplete3 barman
Command 'register-python-argcomplete3' not found, but can be installed with:
apt install python3-argcomplete
Please ask your administrator.

I thought this mightl have happened because I told apt to not install "recommended" packages alongside barman. This is because it was installing a version of postgresql client tools that was not compatible with our environment, eg:

  • for apt-get use --no-install-recommends and --no-install-suggests
  • for aptitude use --without-recommends or -R

But upon looking further, that's not it at all:

Thus I can deduce that it appears that there is an issue where python3-argcomplete doesn't get automatically installed as part of barman (in our environment w/ the EDB repo mirror) at least. The only thing I can think of is perhaps the output from apt show python3-barman where it lists python3:any?

Either way, if someone comes across this in future, hopefully the above will help them. If you have any other suggestions for further investigation please reach out.
