Hi All,

 

I have some freeze behaviour when trying to update nano pi neo 256M.

Apr 28 03:39:52 armbian kernel: [81490.237968] Out of memory: Kill process 18786 (apt-updates) score 55 or sacrifice child
Apr 28 03:39:52 armbian kernel: [81490.237989] Killed process 18786 (apt-updates) total-vm:42264kB, anon-rss:32336kB, file-rss:0kB

 

In normal state the swap seems to be ok

I did "free -m" about 33% max of memory use in normal time

"df -h" show to 71% use max of sd card

But when apt-get update, it slow down boards when it arrives at 97%..... sometimes at 73%

It can take some hours before unfreeze and before kill apt-updates (can't access to serial debug until auto kill updates)

"apt-get clean" seems to make things better working.....

This can avoid freezing everything at midnight when cron auto updates ^^

 

root@nanopineo:/etc/cron.d# cat armbian-updates 
@reboot root /usr/lib/armbian/apt-updates
@daily root /usr/lib/armbian/apt-updates

 

What does "/usr/lib/armbian/apt-updates" exactly do ?

count the number of available package updates to display in the MOTD.

Ok I better understand, thank you for your reply Zador

I have still some freeze (during updates, it's "normal" but I don't want to do updates)
How can I disable all updates in amrbian ?

 

cd /etc/cron.d/
rm -rf sysstat aptitude apt-compat

I try "Freeze" option with amrbian-config...
