I'm gathering more information to add to this forum if I think it's an operating system problem, or i still write in the Citadel forum if I think it's his problem.

Thanks for trying to help, I know I made little information available for a new problem, when I wrote it I thought someone had already gone through it and was just going to send the link with a solution but with the research on the network I understood that I was in an area still not explored. (If there are mistakes in my English, forgive-me because English is not my native language). Then I made some attempts using the binary package already compiled through the command 'apt-get install citadel-mta citadel-suite -y' available on some sites with Citadel tutorial, in this case it appears to install correctly but in the end it doesn't start a server. IOS version: Armbian_20.05.4_Nanopiduo2_focal_current_5.4.45.img.xz write in a 16Gbytes microSD (13% for IOS and about 7GB free) īoard: NanoPi Duo2 512Mbytes RAM (usage of 21%) ĬPU: Allwinner H3, Quad-core Cortex-A7 Up to 1.2GHz Below is some information from my system: After write IOS on mem card and updade/upgrade command I followed the guidelines of the Citadel website which is to execute the following commands: 'curl | bash', but after downloading and starting the installation, many error messages appear due to lack of space.

Previously i try to install ISPconfig mail server on default armbian-config but not work, then i try Citadel because I already have a little familiarity with this program. I need some help, I can't install Citadel mail server on my Nanopi duo2 board.
