[Debian Wheezy] Easy install LinuxCNC

Jerry ,
the lock file is easily fixed , just delete the file called lock
/var/lib/dpkg/lock
it is used to protect , and to allow only one update program at a time , so if you have for instance synaptic package manager open , it wont allow you to use apt-get or aptitude
and same if using aptitude etc , it wont allow synaptic .

sometimes you exit the package application and the lock file does not get deleted .

so use sudo rm /var/lib/dpkg/ lock

i find gedit much easier to use

$ su (enter root password)

Anyway... in terminal I typed

su mongo

WHY? As the error message says, you were not root user, so you were not allowed to install anything. Had you of simply typed "su" (as instructed) you might of got a bit further...

Birchy -

when I typed su (without typing anything else) and hit enter... it asks for a password... I enter mongo...
then I get Authentication failure so it won't allow me to do the aptitude install gedit part.

Cncbasher - In terminal it went like this...

mongo@MONGO:-$ su mongo
Password: mongo
mongo@MONGO:-$ rm /var/lib/dpkg/lock
rm: remove write-protected regular empty file '/var/lib/dpkg/lock' ? y
rm: cannot remove '/var/lib/dpkg/lock' : Permission denied
mongo@MONGO:-$

So that option did not work either unfortunately.

Next step... pulled out 100 foot LAN cable, ran it across the floor to the router and plugged it in... going to Synaptic Package Manager...

I still don't know exactly what I'm doing... but enough to find search and enter gedit... it said there were other dependent files... so I told it yes in response to being asked to install them too... running... and it says successful.

Let me give it a try... yup... I now have GEDIT... whoo!

--> I updated the xxxxxxxxxxx.ini file to make the EDITOR = GEDIT again... also successful.

Thanks,
Jerry

For future reference... to login as root you need to use "su" and NOT "su mongo".

I did... that is what I was saying in the last post... it went like this...

Terminal started...

mongo@MONGO:-$ su
Password: mongo
su: Authentication failure
mongo@MONGO:-$

Could you not also use?

I never log in as root. I simply use sudo before a command that needs root privileges.

Yes, but you need to first add yourself to the sudo'ers list and we don't need any further complications.

jerry add yourself to sudors

sudo gedit /etc/sudoers
( enter your password )

find
# User privilege specification
root ALL=(ALL:ALL) ALL
copy the line and change the word from root to mongo i.e

# User privilege specification
root ALL=(ALL:ALL) ALL
mongo ALL=(ALL:ALL) ALL
save file
then logout and log back in to make changes work

then you can do sudo apt-get -y install gedit
or
sudo aptitude install gedit


another option is to use the root terminal , rather than the standard terminal
their are many ways to do things , as you will find out .

Yeah... new operating system (for me), so new adventures.

I'm getting there... been designing custom panels for friends... getting pretty good at it... not perfect... but pretty good.

Eventually I'll play with PY code and get into GLADE more... but i think I'm doing pretty well with pyVCP.

your doing fine Jerry
just ask if you need assistance , see my profile for email
don't worry linux gets easier over time , then they throw a new spanner in the works , that sets you back to the beginning , and start all over again haha
