Hey there, I am having some issues with installing open vault media onto my raspberry pi. I have followed the official guide, but when I enter this command:
wget -O - https://github.com/OpenMediaVa…Script/raw/master/install | sudo bash
It gives me this error at the end:
The following packages were automatically installed and are no longer required:
eject exfatprogs gdisk libatasmart4 libblockdev-crypto2 libblockdev-fs2 libblockdev-loop2 libblockdev-part-err2 libblockdev-part2
libblockdev-swap2 libblockdev-utils2 libblockdev2 libgpgme11 libnspr4 libnss3 libparted-fs-resize0 libudisks2-0 libvolume-key1 ssl-cert
Use 'sudo apt autoremove' to remove them.
