If you installed MySQL 8.0 and imported OTS schema.sql with default settings, you database uses encoding not supported by MariaDB.
If you dump database using:
mysqldump dbname > dump.sqland try to import it into MariaDB using:
mysql dbname < dump.sqlIt will show error. To fix this, run these 2 commands:
sed -i 's/utf8mb4_0900_ai_ci/utf8_general_ci/g' dump.sql
sed -i 's/CHARSET=utf8mb4/CHARSET=utf8/g' dump.sqlTo take a full screenshot of a site with all “scrolling content” in Google Chrome browser:

sudo systemctl stop apport
sudo systemctl disable apportThen you have to set core file name to core and disable adding PID to core file name. Create file /etc/sysctl.d/99-crash.conf with content:
kernel.core_pattern=core
kernel.core_uses_pid=0Then you have to reload system config:
sysctl --system
