The issue you are facing:
Hello
I have a new server with Ubuntu 20.04 instead of 16.04. I installed Nextcloud and then I put my old data and database to this new server.
Everything seems running, but then I tried to show contacts and photos on the map app. Nothing was working. This I good, because now I know there is a problem with the database. I removed old database, and created new one:
CREATE DATABASE IF NOT EXISTS nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
GRANT ALL PRIVILEGES on nextcloud.* to nextcloud’@localhost;
FLUSH privileges;
exit
mysql -u nextcloud -p nextcloud < /opt/backup/nextcloud/nextcloud-sqlbkp_date +"%Y%m%d".bak
But still the problem:
An exception occurred
while executing
'INSERT INTO
oc_maps_address_geo
SQLSTATE[22001]:
String data, right
truncated: 1406 Data
too long for column
‘adr’ at row 1 at
…/lib/Doctrine/DBAL/Driver/AbstractMySQLDriver.php
line 106
I used the whole day to find out what the problem is, I need help, please.
Is this the first time you’ve seen this error? (Y/N): yes
