Go cookies corrupted

[Michael Skalka]

Spun up a juju controller on localhost, added two machines then logged out of the machine running juju after an hour or so. The following day after logging on and running 'juju status' the following error appears:

ERROR cannot connect to API: cannot load cookies: invalid character '\u0083' looking for beginning of value

Investigation of ~/.go-cookies shows it was corrupted. Deleting/renaming go.cookies allows for access to the controller.

The first two lines of the corrupted go-cookies for reference: <83>Dc^[OX%<95>'Ný÷9¶^\\-^o9Þ[¦âáón^ME<9d>&è]ü½¡ÐÎÆH<81>³¨<8d>Ö<98>^H<83>+aØèõÔ^Nn^Yÿõk^^^W<98>L<8c>*d×<95>õúø£}å4OܳÚ^DùC¿¡ÓéD<9f>p<8d>iþ<80>1^WN<99>z^NN<87>'å^GËjc8[^Ò>qÝ{xzÊ^E¾<86>Æf^D^]ä'<9c>ÀHZ<9a><92>^HP¦-6^]<8b>àoÖ|ÑÏùnTµîc¬+ã)»ÇØ<9d>·<87>VGFX<93>Y^]<8f>ýY¼<9b>^OB^#^Hùê,¼z^EÑvT<90>ß0^OGòÌý^RÕCýûNHJ~Íî!Å

Juju version was 2.0.2

I am not too sure what we can do here - unless Juju caused cookie file corruption...

I cannot really reproduce that. Do you reliably reproduce this with later versions of Juju too?

Thank you for report \o/ It's also great to know that deleting/renaming go.cookies solved the issue.

If you still have the corrupted .go-cookies file, it would be useful
to see it without running through text conversion (perhaps add it as an
attachment here, or post it directly to someone involved if you're concerned
about security risk).

Thanks.

@Anastasia I am still hitting this issue in juju 2.3.5, error occurs when Juju controller node unexpectedly terminates.

calvinh@openstack:~/.local/share/juju/cookies$ cat localhost-localhost.json

Where localhost-localhost is the name of the controller, it contains:

#�oX�

This throws the error:

ERROR controller localhost not found
calvinh@openstack:~$ juju destroy-controller localhost-localhost
WARNING! This command will destroy the "localhost-localhost" controller.
This includes all machines, applications, data and other resources.

Continue? (y/N):y
ERROR failed to destroy controller "localhost-localhost"

If the controller is unusable, then you may run

    juju kill-controller

to forcibly destroy the controller. Upon doing so, review
your cloud provider console for any resources that need
to be cleaned up.

ERROR cannot connect to API: cannot load cookies: invalid character '#' looking for beginning of value

Removing/renaming the file does not fix the issue, not sure how to fix this yet.

@Calvin Hartwell (calvinh),

As per comment # 2, please provide requested file.

[Calvin Hartwell (calvinh)]

@Anastasia it is literally a text file placed in ~/.local/share/juju/cookies with a filename based on the name of the controller, in my case 'localhost-localhost.json'.

The file literally contained: #�oX�

[Calvin Hartwell (calvinh)]

Interestingly when the machine is running, this file contains Nothing:

calvinh@openstack:~$ cat ~/.local/share/juju/cookies/localhost-localhost.json
null

Try replacing the file content with '#�oX�' and then typing juju status, you should get a similar error to what I saw above.

The only way I managed to fix it was to remove the snap and remove everything from ~/.local/share/juju/*

[Calvin Hartwell (calvinh)]

@Anastasia the file has been provided, can you please update?

[Anastasia (anastasia-macmood)]

@Roger Peppe (rogpeppe),

Could you please advise? ^^
