Bug Description

I have a 12.04 server installation that I wish to upgrade to 12.10.
This is an Amazon AWS installation, so I must perform this over SSH, rather than at a console.
I edited /etc/update-manager/release-upgrades and changed "Prompt=lts" to "Prompt=normal", and ran do-release-upgrade.

[[[[[[[[[[ START CONSOLE OUTPUT ]]]]]]]]]]
$ sudo do-release-upgrade

Continue running under SSH?

This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because in case of failure it
is harder to recover.

If you continue, an additional ssh daemon will be started at port
'1022'.
Do you want to continue?

Continue [yN] y

A fatal error occurred

Please report this as a bug and include the files
/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in
your report. The upgrade has aborted.
Your original sources.list was saved in
/etc/apt/sources.list.distUpgrade.

Can you post the results of the following commands run in a terminal?

Hi, thank you for reporting.

One hint to accelerate a handling:

It ishelpfull to set the status of the report back from incomplete if a requested information is provided.

Oh, well, let me do it for you this time.

I am also affected. My results are the same as fisharebest's inside Python. Outside, I get:

$ set|grep LC_
LC_COLLATE=C
    local LC_CTYPE=C;

I believe I installed this system with a preseed that says:

d-i debian-installer/locale string C
d-i pkgsel/install-language-support boolean false
d-i pkgsel/language-pack-patterns string

Workaround:

sudo LC_ALL=C.UTF-8 sudo do-release-upgrade

worked for me.

@RobieBasak - thanks for the hint. I did it this way.

export LC_ALL=C.UTF-8
sudo do-release-upgrade

@BrianMurray - I have a "pre-upgrade" backup, so if you'd like me to test any code fix, just ask.

I don't get it why the fuck developers don't test their creations. Just for the protocol I tried to upgrade from 12.10 to 13.04; my python is 3.2.3 which I CAN'T REMOVE but obviously scripts are for python2.7. Now I should do a clean install -> lost 2 or 3 days to restore the whole system including ~40GB database and stopping our internal VPN server!

Thank you!!!

I think you have a different issue there - none of the error messages match up with the error messages produced by this bug, and your problem is with a different package. It also looks like it could be a local configuration issue, rather than a bug.

I suggest you try community support options. Details are at http://www.ubuntu.com/support/community. It's also wise to test production server upgrades before rolling them out.
