i did it and same that last one:

also i ran updates a few minutes ago from software manager and everything gone successfully. after i did restart as it required.

now resolved?

Im not sure why you're getting permission denied. Maybe with sudo you dont have access to update/upgrade?? Try su - to root account and then try update/upgrade.

sometimes, i got this error most of the time, it executes the update but you cannot see visibly whether it is updating or not.

I tried with su and everything got fine

what is ,,Use 'apt-get autoremove' to remove them" should i run it or? is it important?

thanks for replay and your support erik2282 and all of you who give me their time. Thanks.

Yes. go ahead and run it.

From the man page:

i ran it from su and that is output:
is that ok now? should i do any step next?

reboot just in case and then run apt-get update && upgrade one more time..

Also, since we removed the mozilla stuff from the repos, if you want the latest version of Firefox from the debian repos, run:

This will get you up to 52.2.0 as of today.

ok sir thanks for everything. i will run that commands twice a month right?

On my KDE desktop there is a system notification on my system tray that alerts me when there are updates and usually let that utility run and update my system. I'm not sure what its called but it works great. I have a debian jessie machine at work with Mate desktop and that auto-check utility is not there, well maybe i just need to install it, but I dont care. I just manually run the update/upgrade commands every couple weeks. Im sure you can make a cron job to do this as well.

Thanks
