Hello to all the community! Today I tried to install the server-web Udoo SO I like Debian Udoo quad okay during the intallation until launch "sudo apt-get install mysql-server mysql-client" during the procedure stops and does not restart the server writing "FAIL", and consequently the rest by errors accordingly. Should I reinstall everything on Debian or Ubuntu? I apologize for my English!
The Debian Image is very old (from 2014) so not sure how well maintained. You better use a Udoobuntu Image (latest released 2018)
