Sorry if this sounds silly, but please consider that /etc/bash_completion is *not* included by default in your bashrc/profile. So in order for the completions to work you have to explicitly source /etc/bash_completion in your bashrc/profile.

I have never touched my bash profile and bash_completion has always worked.  Maybe that's an Xfce thing?

I have always sourced only "/etc/bash_completion" (which, BTW, sources /usr/share/bash-completion/bash_completion, which in turns loads all the completions under /usr/share/bash-completion/completions/ ...) and I don't use apt :-)

AFAICT the problem is exactly that /usr/share/bash-completion/bash_completion doesn't source /usr/share/bash-completion/completions

I had to manually include

. /usr/share/bash-completion/completions/*

in /usr/share/bash-completion/bash_completion to get /usr/share/bash-completion/completions completions.

That could definitely be the problem but I already uncommented the lines that source /usr/share/bash-completion/bash_completion in my profile.

After that I had to also include

. /usr/share/bash-completion/completions/*

at the end of /usr/share/bash-completion/bash_completion to get several bash completions to work.

For example, apt package names bash completion only worked after that. Are apt package names bash completion working for you?

Does that happen on Debian also?  I assume so since we pull it directly from their repos.   Please file a bug upstream if there isn't one already.

I'm not sure as I have never used debian but I will look for a bug and fill a new one if necessary.

Thanks!

I noticed that several bash completions weren't available, Like apt for example.

After I included the following line at the end of /usr/share/bash-completion/bash_completion I got all missing bash completions:

. /usr/share/bash-completion/completions/*

Why isn't this directory being sourced automatically?
