Hello everyone, Thanks to useful advice provided by the list community, I was able to upgrade from Koha 3.18 to Koha 19.11.05 I could open the Staff login window. I am now faced with login in to Koha as administrator to perform some maintenance tasks. I managed to found how to get into a Koha shell and run the script /usr/share/koha/bin/devel/create_superlibrarian.pl With Usage: create_superlibrarian.pl --userid <userid> --password <password> --branchcode <branchcode> --categorycode <categorycode> --cardnumber <cardnumber> So I tried with values without any quotes, with double quotes and simple quotes to always face the same error: DBD::mysql::st execute failed: Duplicate entry 'BGH000001' for key 'cardnumber' [for Statement "INSERT INTO `borrowers` ( `borrowernumber`, `branchcode`, `cardnumber`, `categorycode`, `dateenrolled`, `dateexpiry`, `flags`, `password`, `privacy`, `surname`, `userid`) VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ? )" with ParamValues: 0=undef, 1='TLU', 2='BGH000001', 3='CB', 4='2020-05-16T14:29:34', 5='2021-05-16T14:29:34', 6='1', 7='!', 8=1, 9=undef, 10="2"] at /usr/share/perl5/DBIx/Class/Storage/DBI.pm line 1834. But as the superlibraian already exists, then I cannot insert an other one - so the duplicate entry. What I would need is a simple UPDATE statement to reset the password of the superlibrarian with userid thanglong with a "newpassword" Is it safe to enter the following command from a mysql shell USE koha_library; UPDATE `borrowers` SET `password` = PASSWORD("newpassord") WHERE `userid`="thanglong"; I eventually tried it, but still was not able to log in. Any hint on how to reset that password for the first row of the table boowers? Thanks for reading Quynh ================= M.
