Hi,,
No, errors are not expected.
Issues are weird : 
Line 815 : 

2022-02-09 12:35:08.102 ===== TRACE =====  Table "workelement" created.

Good !
Then line 870 :

2022-02-09 12:35:08.472 ===== TRACE =====  Table "workelement" altered.

Good again
Then line 892 

022-02-09 12:35:08.612 ** ERROR ** [] Exception-[HY000] SQLSTATE[HY000]: General error: 7 Error on rename of '.projeqtor_test#sql-5c0_c.frm' to '.projeqtor_testworkelement.frm' (Errcode: 13 - Permission denied) 2022-02-09 12:35:08.613 ** ERROR ** []    For query : ALTER TABLE `workelement` ADD COLUMN `ongoing` int(1) unsigned default 0, ADD COLUMN `ongoingStartDateTime` datetime default null, ADD COLUMN `idUser` int(12) unsigned default null, ADD COLUMN `idActivity` int(12) unsigned default null;

Strange, access denied on rename of something (don't know what) on a query that just adds columns 
Then every quesy on this table fails...

2022-02-09 12:35:10.906 ** ERROR ** [] Exception-[42S02] SQLSTATE[42S02]: Base table or view not found: 1146 Table 'projeqtor_test.workelement' doesn't exist 2022-02-09 12:35:10.909 ** ERROR ** []    For query : ALTER TABLE `workelement` CHANGE plannedWork plannedWork DECIMAL(9,5) UNSIGNED, CHANGE realWork realWork DECIMAL(9,5) UNSIGNED, CHANGE leftWork leftWork DECIMAL(9,5) UNSIGNED;

So you may retry install.
Errors are not normal.
