Ubuntu One account does not stay logged in or does not sign in at all

[Earendil02]

I looked up for updates this morning, but after finding an update for the Clock app, appeared the message:
"Sign in to Ubuntu One to receive updates for apps."
And below a button to sign in.
I found it strange because I never seen this message when updating before, but the real problem is that even if I push the button and sign in, nothing changes and I can't update, same message there.
I also added my Ubuntu One account to the account section of the System Settings panel, but again nothing changes, and when checking the account it had disappeared.
Seems that it can't stay logged in to the Ubuntu One account or sign in at all.

Hi, similar problem here (Aquaris M10, OTA 10.1). After uninstalling one app (pathwind) using UbuntuStore my Ubuntu One account credentials got lost. Next install or update check requires me to sign in to Ubuntu One.

But every attempt to set up the account during app install in Ubuntu Store fails (says "Login error", but the credentials are right).

When checking the Settings -> Accounts section, the Ubuntu One account is not configured and its icon is missing at all in the list - so I cannot even add the account manually.

The only way to temporarily log in is to check for updates, receive the "Sign in to Ubuntu One to receive updates" message, push "Sign In.." button, fill in account credentials, and only then the account is added and update check performed (and update apps installed if there are updates pending).

But any following attemp to install apps via Ubuntu Store results in losing the account again.

Status changed to 'Confirmed' because the bug affects multiple users.

Another detail: when I fill in correct credentials, it says "Login error".
When I fill in incorrect password, it says "Network error". Really weird..

This problem has hit me in the last two weeks (Meizu MX4), and I can't install *any* upgrades. HELP!

Argh... after reading the above (yeh, I know...) I went into the accounts settings and put my credentials in there, then returning to the updates page I could request the updates only to be hit by a 401 UNAUTHORIZED error.

Same here, it prevent me from receiving Telegram's notifications also

Partially solved by removing folder /home/phablet/.config/libaccounts-glib (it removed all online accounts, obviously), now it stays logged, but I still get 401 UNAUTHORIZED when trying to install any upgrade

I was wrong, it solved it for just a few tries, then it was broken again
