No way to reset admin password - Grafana - Raspberry

After the last upgrade I am unable to reset the admin password.
I am on Grafana v6.1.2

I did try with CLI:

pi@raspberrypi:~ $ sudo grafana-cli admin reset-admin-password admin
INFO[08-09|09:13:40] Connecting to DB                         logger=sqlstore dbtype=sqlite3
INFO[08-09|09:13:40] Starting DB migrations                   logger=migrator
INFO[08-09|09:13:40] migrations completed                     logger=migrator performed=0 skipped=330 duration=4.119655ms

Admin password changed successfully ✔

I did try with sql-lite:

sqlite> update user set password = '59acf18b94d7eb0694c61e60ce44c110c7a683ac6a8f09580d626f90f4a242000746579358d77dd9e570e83fa24faa88a8a6', salt = 'F3FAxVm33R' where login = 'admin';

Nothing! I still get invalid username or password!
Any hint? I don’t know what else to try.

Something was corrupted. I had to remove and reinstall Grafana from scratch
