Linux Mint Forums

i am using dell precision T3500 work station 64 bits with 6 core.

My mint version is as per follow:

/Desktop $ lsb_release -a
No LSB modules are available.
Distributor ID: LinuxMint
Description: LMDE MATE Edition
Release: 1
Codename: debian
@dell ~/Desktop $ cat /etc/lsb-release
DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=1
DISTRIB_CODENAME=debian
DISTRIB_DESCRIPTION="LMDE MATE Edition"

But when I type following command :

sudo apt-get update

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

I read on google that error like not get lock ( first error ) is likely due
to other process ibs in work. but I not using any other process.

Are you sure you don't have mintupdate or the software center open?

Yes sure.
I reboot the system and did the mentioned step again( as per my 1st post) & i got
same output.

Where is the problem I not able to figure it out.
is the problem in apt-get or with my system ????


I will be thankful for any help.

With best wishes,

100 %? If you installed LMDE today you probably did not change the settings of mintupdate. It has a stupid setting to start almost immediately after booting and then check repos every 15 minutes and thus mintupdate is bound to be in the way.
If mintupdate's icon just shows the shield without any content it is doing something and blocking software manager, package manager and anything else depending on apt (like running apt-get). In my opinion it is better to change mintupdate's settings to 4 hours or something like that. This way it will check once after booting and then wait the set time before checking again. Most days there is no update at all so it doesn't make sense checking every 15 minutes.
The second part might be a temporary problem with the server. Run mintsources and change to another mirror to ensure that it is not the mirror that's causing the problem.
