I like having the user interface of my Linux Mint 19.1 in English, but the regional settings such as numbers and currency in a different language such as Swiss German.
Unfortunately, the date and time settings are set as part of the Language Settings and can not be controlled individually. As a consequence, the Lightning Calendar extension in Thunderbird displays the time as a.m / p.m instead of the desired 24h time format.
Override the system setting of the time format by adding the following two lines to your .profile file:
LC_TIME=de_CH.UTF-8 export LC_TIME
You can find the text file .profile in you home folder (enable hidden files in Nemo first).
For security reasons, creating symbolic links in a shared folder is disabled in the guest OS (ticket 10085 and manual 5.3 Shared Folders). If you trust your Linux guest OS, you can enable symlinking from the host OS with the following command:
Quick cooking recipe to install PHP oci8 on Linux Mint 17 / 18.
Download the Instant Client from the Oracle Website and follow the instructions at the bottom of the download page.
Download the Instant Client SDK from the same location, unpack it and move the SDK folder to the same folder where the Instant client is installed. On Linux Mint this would be “/opt/oracle/instantclient_xy”
“sudo pecl install oci8” and give path to your instant client when asked
Add “extension=oci8.so” to your php.ini located at “/etc/php5/apache2/php.ini”
restart apache “sudo apache2 -k restart”
Note: You can use phpinfo() to locate the used php.ini
If your Linux (Mint) fails to boot because you broke the /etc/fstab, for example, you’ll end up with a ready only root shell. The trick is to mount the root partition to as read-write without actually unmounting it:
# mount -o remount,rw /
After doing that, you wil be able to edit /etc/fstab, correct the error, and reboot normally.
