Vážení přátelé pokud by jste si našli chvilku a spustily kontrolu cron.daily a napsali mi zda je vše v pořádku. Již u 3. nové instalace Ubuntu 14.04 (včetně nových aktualizací), cron.daily nedoběhne dokonce a zasekne se u úlohy apt. Je potřeba přeinstalovat libcrack2 a cracklib-runtime. Nevím zda bylo nutné, ale doinstaloval jsem i cron-apt. Potom vše proběhne v pořádku.
Pravděpodobně se jedná o bug, a tak vás ještě jednou žádám o test.
sudo -i
run-parts -v /etc/cron.daily/
po případě
run-parts -v --reverse /etc/cron.daily/
-
A že bys třeba dal výpis co ti ty příkazy vypíšou? A co vůbec v tom CRONu máš?

takto je to po zásahu, před tím se cron sekne na úloze apt. Jediné co jsem přidával je úloha na fstrim
#!/bin/sh
LOG=/var/log/trim.log
echo "*** $(date -R) ***" >> $LOG
fstrim -v / >> $LOG
fstrim -v /home >> $LOG
-
Stáhl jsem nové médium nainstaloval ve VB a kupodivu to samé :o.
Cron.daily se seká u apt a nedoběhne do konce.
-
U mě žádný problém, systém rok starý.
-
Díky za reakci, bude se pravděpodobně jednat o chybu u nové instalace 14.04.2. Bohužel starší instalace mi nikde neběží. Momentálně prolézám launchpad a podobnej bug tam nenacházím. Reporting bude pro mě s mojí ang. trošku problém, ale musím se s tím trošku popasovat. Ale pokud máte někdo zkušenosti reportněte to za mě. Protože jestli mám pravdu jedná se o závažnou chybku.

zjisti, v cem je chyba, na cem to visi ... dej sem obsah toho apt, pokud je to shellovy skript, tak kdyz do nej das na zacatek tohle, tak ti to vytvori soubor ve var/tmp, ve kterem bude zadenikovano, o co se pokousel

Nejsem programátor, ale připadá mi to jako když se to kousne když se snaží připojit k zrcadlu s aktualizacema.

Mě se spíš nezdá random sleep, ale možná se mýlím, skript jsem jen přelétl očima.
+ sleep 891
-
Ano, pokud log končí sleepem na pomalu 15 minut, možná by jen stačilo počkat. Ten random sleep je v pořádku, to je záměr, horní hranice je 30 minut, je kvůli rozložení zátěže serverů s repozitáři při spuštění většího množství systémů najednou. A pokud se úlohy cron.daily spouštějí synchronně, tak je jasné, že ty další holt musí počkat.
-
Ještě jsem zjistil, že při spuštění na mém systému se funkce random_sleep vůbec ke slovu nedostane, ale jsem líný studovat zbytek kódu, který o tom rozhoduje.
-
No ono stačí doinstalovat apt-cron a přeinstalovat libcrack2 a cracklib-runtime. A proběhne to do 20 s.

Asi na to nepřijdu, prosím uzavřít :'(
