i run ubuntu 16.04 lts , mysql server version: 5.7.15-0ubuntu0.16.04.1 (ubuntu). works seemingly fine, sever status not. the error message is: "unhandled exception: timestamp out of range platform time_t". python error. when run mysql through shell, status reports following: any clues why uptime screwed? how 1 fix uptime in order avoid platform time_t error in workbench application? my uptime: just guess - have ntp sync enabled? having same issue on ubuntu 12.04 hyper-v guest. when ubuntu boots, mysql being started prior time sync , gets nice eternal uptime. simple solution - service mysql restart. proper solution - make sure mysql service starts after ntp sync.

(copied answer here , since saw first, , doesn't seem right mark duplicate of question asked later.) guest sessions locked down using apparmor, uses long list of special permissions keep guest users touching anything. these accessed etc/

i want copy ~50gb folder 1 server another. understandably going take quite while, i'd able perform "in background". using standard scp command requires me keep console open. read nohup , seems should trick, i'm struggling work. seems require console left open - after typing in command, nohup program remains open, , if press ctrl + c exit transfer stops. misunderstanding nohup does? or how else can achieve this? the name nohup refers hup signal, traditionally sent processes when (telephone-)line terminal connected through server hung up. nohup prevents signal being sent, when "hanging up" nowadays means "closing terminal window". tl;dr want close terminal window (or kill ssh connection on side) instead of logging out of server regularly. nohup keep process running, if terminal connection breaks in 1 way or another.

i installed ubuntu on windows 7 machine , have used few tools in past recover data ssd after has been erased. wondering if there way clean hdd in way data windows 7 cannot recovered. have 200gb on sda1 , want make sure available 200gb nothing recoverable. sudo dd if=/dev/zero bs=1m of=/dev/sda1 be sure never want sda1 , because gone forever. on system works @ 100 megabytes per second, 200 gigabytes take 2000 seconds or 40 minutes. if sda1 ssd both overkill , useless @ same time; it's overkill because sudo blkdiscard /dev/sda1 very faster, , useless because ssds not overwrite physical blocks. there no absolutely safe way delete data off ssd if adversary cheka; however, if adversary cheka mighty power of soviet state behind have greater , more urgent problems wiping data off disks.
