Deleted all on log but still the same. cant run apt-get -y autoclean as there is not enough room to run it!!!! i had a command that i found in the forums that frees up the space but cant remember it, where it is!! i lost it with reinstall. bit crazy that a system like proxmox would just choke itself like this, not exactly produciton environment software.
du cmmand above producess error on some folders i think, it doesnt find anything big.
