i have just got parrot os and would like to download and run beEF, i can download the folder, but when i try to run the install command i get the following message:
E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 4982 (apt)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another >process using it?
Im new to all this, i have switched the computer on and off to make sure there is no other process using it.
Does anyone know what i need to do?
Kind regards
It happens because u run command to install/update/upgrade on another terminal. Kill the session and try again

I can't load any webpage in browsers (mozilla and chrome).
Also i can't execute sudo apt update command, because my file /var/lib/apt/lists/lock locked by process 917.
But my computer has internet, because messengers like telegram is working.
And i can execute command ping -c5 8.8.8.8 and it loads packages fine.
Can someone help me please?
Regarding the issue with apt, you likely have another instance of apt running somewhere. You really don't want doing multiple operations on your system's packages at the same time so apt automatically sets a lock file (/var/lib/apt/lists/lock) to avoid that.
tl.dr. find the other running instance of apt and kill it if appropriate. If you cant find any (can happen sometimes), delete the /var/lib/apt/lists/lock file yourself (please see https://askubuntu.com/a/335801).
I am getting this error as:
apt-get: error while loading shared librarie: libz.so.1:cannot open shared object file: No such file or directory
When trying:
sudo apt-get zlib1g
I'm using a Ubuntu 16.04 os and i can't log into the graphic interface, after booting I can only see a blinking underscore on the top left corner of the screen, so i pressed "alt+f4" to open a terminal session.
In my commands historical I found the command:
rm -rf zlib-1.6.37
(That command was executed from the root directory of my user.) And i don't know if that is the cause.
I do need some solution to thia problem as soon as possible please.
If you need some more info just ask for it, I will reply with the answer as soon as I can.
Ok, I've figured it out, it was quite simple, but i just got desperate
The solution was just to recreate the symlink that was damaged (libz.so.1) and that fixed the problem, now I have another issue, it seems like I'm connected to network but i don't have internet at all anyway that's for another question.
Thanks if somebody tried helping me, even if the question just have like 2 hours from posted.
Alright, just a disclaimer: I've been using some version of Unix or Linux for 30 years, I have good working knowledge, but when it comes to administration I'm enthusiastically dangerous :)
Every time I do the automated OS upgrade in Pop!_OS something bad happens. And I am not talking about apt update / apt dist-upgrade. I do mean going into the settings GUI and in the last item on the list clicking "Upgrade".
Last machine I did it on failed and I couldn't recover the system, not even from a bootable stick. That machine was on it's last leg, I just let it go and built a new box, it was time. Well here we are again, time for an upgrade to 20.10.
I hit "upgrade os" (maybe it's "update os" I don't remember exactly
It did some stuff, and said it needed to restart - Okay so now we're windows? Not thrilled
Restart and end up at a gray screen where it sat at 0% progress bar for the update
I let it sit a good long while, maybe 45 minutes, I was worried this mid-low range machine was just taking a while, nothing
Cringe.. hit the reset button, the system rebooted and did "something" and then came up seemingly okay
Now here's the problem list:
Did the upgrade happen fully, completely, and successfully? How can I tell? This feels like I'm running windows and just rolling in the blind mystery..
VMWare Workstation wont launch. Nothing happens with icon click, from command line I get this error:
/usr/bin/vmware: line 105: 159580 Segmentation fault (core dumped) "$BINDIR"/vmware-modconfig --appname="VMware Workstation" --icon="vmware-workstation"
Searching online a bunch there was a lot of talk that there may be permission problems after upgrade and running it as root would help. This did not work. I read that upgrading to VMWare 16.x will help. I'm open to it, but on principle WHY does this have to be the case?
I use another app that is installed from source, it's called MakeMKV. I've had no trouble with it until the Pop upgrade. Again, it doesn't launch from the icon. I rebuilt and reinstalled it. No go. Launching from command line returns:
/snap/makemkv/217/bin/desktop-launch: line 51: /home/ritchie/.config/user-dirs.dirs: Permission denied
qt.qpa.screen: QXcbConnection: Could not connect to display :1
Could not connect to any X display.
Launching from the command line with sudo worked though! So wtf?
This feels like a key piece of the puzzle, that bit about not being able to connect to the display.
Since this post is so long I wont list the hardware, but am happy to if it helps diagnose.
Any help is appreciated!
got the same with other snap packages...
tried to figure out what's wrong...
looks like some ENV variable is not set properly causing the error:
.config/user-dirs.dirs: Permission denied
but simply reinstalling the package resolves the issue:
sudo snap remove %package%
sudo snap install %package%
I used a library (the library is called cublas) in my CUDA code which I 'm writing in linux, I can compile my code successfully using nvcc but when I run the code I get this error:
error while loading shared libraries: libcublas.so.7.5: cannot open shared object file: No such file or directory
I found This link as a solution which suggests to run some commands in order to solve the issue. one solution based on this link is running the following command:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib
The system which gpu locates in it and I am using to run my code on it is shared between me and other people, I am not a sudo user in that system. I am wondering if running this command is safe and does not affect other settings of the system
Can anyone please help me to know that>
Thank you so much
I am wondering if running this command is safe and does not affect other settings of the system
Yes, you'll be fine.
This command:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib
only affects the process you execute it in.
It will not affect any other user's process, or any other process of yours.
Furthermore, if you log out and log in again, you will have to execute that command again. It is not "sticky"
I'm using openSUSE 13.1 with Xfce 4.10. I'd like to make a lock screen more pretty. I read that I can remove xscreensaver and install gnome-screensaver instead and I did it. When I try to run it (using command gnome-screensaver) then I get message ** (gnome-screensaver:2208): WARNING **: Couldn't get presence status: The name org.gnome.SessionManager was not provided by any .service files. And I stucked here.
Question: What to do to go further or how can I make the lock screen more pretty?
