Solved Profile Duplicated on Sync

Vivaldi default profile get corrupted (self duplicated), now sync backup is unrecoverable

Hello,

I got duplication of same default profile. After one duplicate suppression, I got (r-)ejected of remaining profile. I logged again.

But my sync key (or pass) is rejected.

I removed all profiles on machine. Creates a new, login, then, still sync pass still refused.

Tried to go into a VM with Vivaldi and same account. Sync got rejected when started Vivalvi and now sync key or pass is rejected too on this second machine.

I can only conclude for now that Vivaldi first corrupted itself. then corrupted all sync data, making sync unrecoverable.

I will restore from a manual backup 10 days ago. Clearly sync implementation is fragile, can easily broke and never recover.

What are my other options now?

@lboulard I propose resetting the encryption password. This will delete your data from the server, but you will still have it on your computer.

ATTENTION! Do this on the machine that contains all your data. If they both have the same data, you should probably make the process on your real machine, not the VM.
First, log out from the computer and when logging in again, click forgot password when entering the encryption password and reset it. Then choose another password and turn "Sync all data" on. This should collect your data from the computer and make it available to sync. Please let me know if you managed to do something.

After more investigation, I found that in "Local State" JOSN file. I have in "profile"/"info_cache", 2 conflicted entry: "default" and "Default". Good recipe for data corruption.

Sadly, my backup also contains this state.

Finally, after restoring from a backup, backup restored itself.
On Windows VM, I was able to restore sync using a new export of the key. Original sync pass seems no longer valid.

@lboulard So now you can sync your older data or no? I don't understand...

lboulard

@ThePfromtheO sorry not full clear for me too.

In more details, on main Vivaldi:

Create a new profile (im LOCALAPPDATA/...), restoring from my backup.
Notice that backup is now working again from this backup.
Hae to restore workspace manually but everything else seems good.

On Vivaldi in VM:

Same profile as before, no sync working, still refusing key or pass
New export of key from main Vivaldi
Import key to sync on VM Vivaldi
Sync work again (old working key seems to have become incorrect)

@lboulard So...The working key is the one that is not working? Did you try to change it?

ThePfromtheO

@lboulard Or, not depending on the key, you can't sync the data?

ThePfromtheO

@lboulard Yes, the workspaces are not automatically synced. You can visualise them in another place. But first, let's try to solve your problem.

@ThePfromtheO current of state of sync pass/key

At corruption time:

sync pass (main machine): not working
sync key (main machine): not working
sync pass (VM machine): not working
sync key (VM machine): not working

After going back to backup in new profile of main machine:

sync pass (main machine): not tested (sync restored by itself)
sync key (main machine): not tested (sync restored by itself)
sync pass (VM machine): not working
sync key (VM machine): not working

Create a new backup of key on main machine:

sync pass (VM machine): not working
sync key (VM machine): working using NEW backup key from main machine

If I compare both key backup on disk, there no longer match.
I looks like key changed. No idea how it is possible.

Note that both main and VM machine with Vivaldi started a few months ago from same sync pass (not sync key).

note that I have been able to resolve issue from a backup. Now, I am curious how the sync key can change!!

ThePfromtheO

@lboulard Do you mean the "Encryption Key"?

ThePfromtheO

@ThePfromtheO The one from the right?

lboulard

@ThePfromtheO yes

sync pass: Encryption Password
sync key: Encryption Key

ThePfromtheO

@lboulard Sorry for the late answer. I thought to test this on my laptop, but I'm using Ubuntu and there could be some differences between Windows and Ubuntu Vivaldi apps. Maybe @DoctorG or other volunteer could help you.

@ThePfromtheO As I see here, it says not if you can change the encryption key.

ThePfromtheO

@lboulard Why don't you use the encryption password only?

ThePfromtheO

@ThePfromtheO The encryption key is only an extra option if you forget your encryption password...

lboulard

@ThePfromtheO Why don't you use the encryption password only?

Because encryption password is no longer accepted.
And (former) encryption key backup is no longer accepted.

I was lucky to be able to restore a working sync from backup. Then made again a new encryption key backup. Detect that encryption key changed (hu?). Then on another machine, restore sync using the new encryption key.

So now, I have a working encryption key backup. But a invalid encryption password.

My hypothesis is that profile duplication on main machine lead to a new encryption key. Of course, this got unnoticed on my side until I removed duplicate profile. Other machine (VM), vivaldi was unused for a few months, so did not notice that sync was broken here too.
