hi as many of you can see i am a newcommer on LQ and am trying to get some help.

the problem i have have is that i have installed metasploit(metasploit-framework-4.16.16+20171109102338.git.1.c5fd027~1rapid7-1.el6.x86_64) from the official metasploit repository using the automated linux installer and beore the recent update it used to work just fine , i was able to use its full functionality . but now i just get an error . is it because in the recent update there was one for metasploit too . i really don't know , i may be a learning ethical hacker but i am still new to linux .

whenever i try to run commands like :

1.msfconsole
2.msfvenom
3.msfd
4.msfrpcd
5.msfpayload
6.msfencode

it basically just gives me the same error (which can be seen below) :

You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated ../../opt/metasploit/apps/pro/Gemfile.lock to version control.

If this is a development machine, remove the /opt/metasploit/apps/pro/Gemfile freeze
by running `bundle install --no-deployment`.

The list of sources changed

You have deleted from the Gemfile:
* source: source at `engine`
* source: source at `ui`
* metasploit-pro-engine
* metasploit-pro-ui

i don,t kn ow how to deal with this problem , a post with detailed help by anyone interested to help will be highly appreciated .

Ok, so did you try doing what the message SAID???? Did you run "bundle install"?? And you really need to read the LQ Rules and "Question Guidelines". Text-speak isn't a good thing to use here, and unless you provide details when asking questions, there's no way we can help. You don't tell us what version/distro of Linux, what has changed (since this WAS working), anything you've done/tried so far, etc.

i have been using the same distro with a simple kernal version change from the point it was working to not-so-working .

was working : 4.13.11-200.fc26.x86_64 (on running uname -r)

is not working: 4.13.12-200.fc26.x86_64

when i am running the "bundle install" it simply says the following:

"Could not locate Gemfile"

i am not a expert in linux stuff and am new in LQ and will from next time definetly follow the rules .

Try: pwd
Did you run it "elsewhere"? (Use Google if don't know what something means.)

Also, have you spent=devoted at least a couple hours, to web-researching all the message output?
I find lots (but I'm spending my days on 32 bit efi, sorry, so I don't have any good help here).

Best wishes; let 'us' know!!!

p.s. Here's one of my searches: "Could not locate Gemfile" metasploit|fedora

p.p.s. (added since you haven't read my post yet, per username->ViewPublicProfile):
I might suggest (tho semi-OffTopic), since CEH will need to write high-quality reports,
that you painstakingly Edit #1 (for only gramatical errors; do not change content, as that would be considered 'cover-up'). I'm just trying to be helpful to your 'soft skills'.

Still not telling us version/distro, but we can try to ASSUME you're using Fedora 26, right? And are you saying there has been a kernel update? And did you read/follow the Fedora instructions??? http://fedoraproject.org/wiki/Metasploit
Reading the instructions should be the first thing you do with ANYTHING, not just Linux.
