I am running a "amd64" version of jessie and in an effort to get
'crossover_14.1.11-1.deb' installed, which is 32-bit. To do this I issued the
command -

╭────
│sudo dpkg --add-architecture i386
╰────

and then -

╭────
│dpkg --print-foreign-architectures
╰────

then I did a 'apt-get update' and tried to install crossover again. I've
now given up trying to instal it and wish to move back to just being a
64-bit machine using amd64 packages only. I've therefore done -

╭────
│sudo dpkg --remove-architecture i386
╰────

which failed saying -

--8<---------------cut here---------------start------------->8---
dpkg: error: cannot remove architecture 'i386' currently in use by the database
--8<---------------cut here---------------end--------------->8---

How then can I remove 'i386' please, or should I just cut my losses and reinstall?

Thanks
Sharon

Do you still have any i386 packages installed? I think running

  dpkg -l "*:i386"

should list them (I don't use multiarch myself, but it works for the
native architecture and "*:all").

I can confirm on my multiarch system that the command you suggest will 
do what you intend.

Wow, that *is* a lot! But I don't think that they're all installed, ATM.
I don't know what the "rc" means though.

Thanks

It's not the clearest unless you're looking for it, but it's in the
header at the top of the output. "r" means "Remove", "c" means
"Conf-files", i.e. the packages have been (or are about to be) removed
but still have configuration left. A normally installed package would
be shown as "ii", by comparison.

I think that I've resolved the situation by -

--8<---------------cut here---------------start------------->8---
deb     [arch=amd64] http://foo
deb-src [arch=amd64] http://foo
--8<---------------cut here---------------end--------------->8---

in my sources.list.

I installed all amd64 packages that were shown as being removed in
yesterdays logwatch, and then I manually removed all the i386 packages
From /var/cache/apt/archives and then rebooted.

Everything came back up successfully, and I then "sudo dpkg
--remove-architecture i386" and checked using "dpkg
--print-foreign-architectures" which showed a zero response, and I then
"dpkg --print-architecture" which showed "amd64"!

Mission accomplished!

Thanks
Sharon.
