If it's helpful, the console script errors on all commands right now:

/home/analytics/piwik$ ./console 
The directory "/home/analytics/piwik/tmp/cache/tracker/" does not exist and could not be created.
                                                                               
  [InvalidArgumentException]                                                                         
  The directory "/home/analytics/piwik/tmp/cache/tracker/" does not exist and could not be created.
  

and the error message I get when I attempt to log in is:

Error: You can't access this resource as it requires 'view' access for the website id = 1.

This issue has been reported by multiple other uses on the forum at https://forum.matomo.org/t/cannot-sign-in-after-update/31321/2

The error message I saw is the same mentioned on the forum,

SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘xxxxxx.piwik_brute_force_log’ doesn’t exist

I also got this
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'mydatabase.piwik_brute_force_log' doesn't exist

I could continue with the update though, needed to re-login.

Probably related to #13836

Kind a tells you, that Matomo doesn't do even basic QA of the upgrade.

here my error:
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'db570XXX_4.matomo_brute_force_log' doesn't exist

I found, that you need to click "Back to Matomo", and it will ask you to Upgrade DB, which adds new (missing) table

👍 Same happened to me on 1 VPS server running Matomo, and I could not log-in from any of my devices afterwards (all PCs, mobiles where I was logged-in before auto-update).

[Tue Jan 22 H:i:s] [:error] [pid 12176] [client ***] Error in Matomo: Mysqli prepare error: Table '***piwik_brute_force_log' doesn't exist, referer: https:// *** /piwik/index.php?module=CoreUpdater&action=oneClickUpdate

( btw. you are using html special characters encoding in PHP log files - why? )

FIX
I have closed my browser, (I am aware of these kind of auto-update hickups in Matomo since 3.x Piwik time, so I was playing cool), then tried to access Matomo again, which prompted me then with new message that update was successful in fact, and just skipped to the last part, which was in the installation loop (Upgrade Database part). One more restart of browser and it was completed, but now log-in page was presented, and I was stuck in the log-in nightmare loop.

Then, I have cleared application cache (alternatively delete your cookies on mobile for Matomo/Piwik website), restarted browser and now finally I can normally log-in back.

Off-topic: Btw. my file ownership and permissions are in order, every other PHP app can read/write there just fine, except Piwik/Matomo for couple of major update releases now (3.x something). Every time I have to manually run commands in terminal to remove obsolete files - Why? Something is definitely not right there. If this was truly the case, temporary and cache files errors would be present in the first place, which aren't (they are normally created, including sub-dirs etc.).

+1

i can't relogin.... i've deleted the cache and it doesn't work.

You will probably have to create the missing database table and update database manually:

See Matt's answer here: #13836 (comment)
Manual update (from terminal / ssh console): #13990 (comment)

Also, do not use your bookmark, instead, try to access to your 'root' matomo folder without any URL parameters (index.php?etc...).

Same problem about missing table here - both, on a Debian and a FreeBSD server:
SQLSTATE[42S02]: Base table or view not found: 1146 Table '<myDatabaseName>.piwik_brute_force_log' doesn't exist.
