Further update...so we discovered that there is not enough space in / dir when checking to update to recommended jumbo 150 for R81.10, so since reboot failed to fix the issue, advised Viktoria to have her colleague extend the HDD, add 4 more GB of ram in vsphere, boot up the box and check the space. If same problem, boot into maintenance mode, run lvm_manager, try expand the / dir that way, reboot again and try ips update.
