This is an old enough bug while using MySQL version 5.5 with Ubuntu 14.04.
According to these issues form docker or moby repository:
https://github.com/docker/for-linux/issues/72https://github.com/moby/moby/issues/35503
overlayfs only supports a subset of the POSIX standard.
But the problem does not arise when using aufs.
We do a little trick to MAKE MYSQL GREAT AGAIN.
NOTICE: Only people who are using docker may face this problem.
If you are using a bare-metal system or just running a virtual machine,
executing the installation script without using container works fine.
Update base system to Ubuntu 18.04.
.htaccess file's session path changed correctly.
Add gnupg install choice, due to base system has no gpg support.
Set DEBIAN_FRONTEND to noninteractive in order to prevent tzdata stuck.
Change Dockerfile's verion and buanch checkout method, in order to save space.
Fix mysql conf when not restart service and the database can't import judger info.
Change install.sh, support PHP7.2, update libv8 repo to artful, with missing php-mbstring.
The old JDK distfile mirrors are deprecated, changed to official.sed modded to get the latest jdk8.
BREAKING CHANGE: Ubuntu 14/16 users shouln't execute this script, due to config files and packages not the same.
Change the base Docker image to ubuntu16.04 and change the LAMP
packages to support PHP7.
BREAKING CHANGE: the packages which will be installed has changed.
