Odroid C2

I just installed dietpi (1.59) on a OdroidC2. After apt-get update && apt-get upgrade i get this error: (what should i do?)

Do you want to continue? [Y/n] Y
Extracting templates from packages: 100%
Preconfiguring packages ...
(Reading database ... 24292 files and directories currently installed.)
Preparing to unpack .../libc6_2.19-18+deb8u10_arm64.deb ...

LD_LIBRARY_PATH contains the traditional /lib directory,
but not the multiarch directory /lib/aarch64-linux-gnu.
It is not safe to upgrade the C library in this situation;
please remove the /lib/directory from LD_LIBRARY_PATH and
try again.

dpkg: error processing archive /var/cache/apt/archives/libc6_2.19-18+deb8u10_arm64.deb (--unpack):
 subprocess new pre-installation script returned error exit status 1
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

Sorry, just found the solution:

#export LD_LIBRARY_PATH=/lib/arm-linux-gnueabihf:/usr/lib:/usr/local/lib:/opt/vc/lib



(to make the change permanent)

ps: After a apt-get update/upgrade REBOOT!!!
