I was using a friend's laptop with an Ubuntu 16 OS. I was asked
to clean the historic files an after browsing a few websites, I used: 



cat /dev/null > ~/.bash_history


command which appear not to work (I was not asked to input any password).
I then believe I used the command below, which I was asked to
plug in the laptop's password:



sudo gedit .bash_history


As soon as I pressed enter, the internet connection went down.
I tried to connect the internet back, but the computer could not
locate any wifi signal.



I appreciate any help you can give me to resolve this problem.
Thank you.

    (1) unless you were opening webpages by passing the URLs to a browser on the command line, there's no reason for your .bash_history to contain information about your web browsing history (2) the cat command wouldn't need a password so that's not a reason to believe it didn't work (3) see Why should users never use normal sudo to start graphical applications?

  • Have you tried rebooting the machine after bleach bit or whatever you ran, If the network managers status failed, you may be dealing with a larger issue that just a simple clean up, As in It would help knowing his previous tampering with the network managers, not just gnomes. Two Network Mangers may be causing the conflicting if you can't get one or thee other up.

  • With that being said though and as strange as it may sound, any USB plugged devices can disrupt the services if they experience an error in operation, so If any hotplugs are in, try unplugging them, rebooting the machine and then running service network-manager restart and service networking restart followed by a status check, It's happened to me before :/

  • Hi hello moto I tried your suggestions above. Once restarting the network manager, I got a window popping in saying internet was disconnected. Service manager is running active. Unfortunately I cannot connect to the internet still..

  • Do ls -la ~/.bash_history lets see the ownership and paste it into your question not into another answer!

    (1) unless you were opening webpages by passing the URLs to a browser on the command line, there's no reason for your .bash_history to contain information about your web browsing history (2) the cat command wouldn't need a password so that's not a reason to believe it didn't work (3) see Why should users never use normal sudo to start graphical applications?

  • Have you tried rebooting the machine after bleach bit or whatever you ran, If the network managers status failed, you may be dealing with a larger issue that just a simple clean up, As in It would help knowing his previous tampering with the network managers, not just gnomes. Two Network Mangers may be causing the conflicting if you can't get one or thee other up.

  • With that being said though and as strange as it may sound, any USB plugged devices can disrupt the services if they experience an error in operation, so If any hotplugs are in, try unplugging them, rebooting the machine and then running service network-manager restart and service networking restart followed by a status check, It's happened to me before :/

  • Hi hello moto I tried your suggestions above. Once restarting the network manager, I got a window popping in saying internet was disconnected. Service manager is running active. Unfortunately I cannot connect to the internet still..

  • Do ls -la ~/.bash_history lets see the ownership and paste it into your question not into another answer!

I was using a friend's laptop with an Ubuntu 16 OS. I was asked
to clean the historic files an after browsing a few websites, I used: 



cat /dev/null > ~/.bash_history


command which appear not to work (I was not asked to input any password).
I then believe I used the command below, which I was asked to
plug in the laptop's password:



sudo gedit .bash_history


As soon as I pressed enter, the internet connection went down.
I tried to connect the internet back, but the computer could not
locate any wifi signal.



I appreciate any help you can give me to resolve this problem.
Thank you.

    (1) unless you were opening webpages by passing the URLs to a browser on the command line, there's no reason for your .bash_history to contain information about your web browsing history (2) the cat command wouldn't need a password so that's not a reason to believe it didn't work (3) see Why should users never use normal sudo to start graphical applications?

  • Have you tried rebooting the machine after bleach bit or whatever you ran, If the network managers status failed, you may be dealing with a larger issue that just a simple clean up, As in It would help knowing his previous tampering with the network managers, not just gnomes.

  • With that being said though and as strange as it may sound, any USB plugged devices can disrupt the services if they experience an error in operation, so If any hotplugs are in, try unplugging them, rebooting the machine and then running service network-manager restart and service networking restart followed by a status check, It's happened to me before :/

First of all, you need to check whether the network-manager is running fine or not? Please use the below command and see the status.



service network-manager status


If everything is fine, it should show running(active) status, otherwise, you may see some error here.



If the network-manager is not running, try to restart the network-manager using the below command:



service network-manager restart


(You may need sudo access to run this command.)

  • @user678722 Can you please post the last 100 lines of dmesg while restarting the network. First restart the network-manager using the command above and then run the below command to get the last 100 lines. dmesg | tail -n 100 and post the output by editing your question. Also, post the last 100 lines of /var/log/messages just after restarting the network-manager

Thank you for your answer. I followed your advice yesterday and the network manager was indeed running (active).
There was a line of code stating a "fail" when I ran the "nework-manager status" command:
"failed to enumerate oFono devices: GDBUS.Error:org.freedesktop.DBus.Error.Serv



Not sure if this will bring any clarity for the outstanding issue, but hope it can help as the computer states the wireless connection being "out of range".
I did try to enable the Wifi through a slide button, but the system did not allow me to do this.



Unfortunately, I am really lost on how to resolve this. I'll be appreciated for any further suggestion/advice.
Thank you.

  • When an error occurs always read your logs with dmesg | tail -20 or journalctl --follow, Then add grep for specifics or egret for a range to narrow down your issue, as in journalctl --follow | egrep "error|corrupt|missing"

First of all, you need to check whether the network-manager is running fine or not? Please use the below command and see the status.



service network-manager status


If everything is fine, it should show running(active) status, otherwise, you may see some error here.



If the network-manager is not running, try to restart the network-manager using the below command:



service network-manager restart


(You may need sudo access to run this command.)

  • @user678722 Can you please post the last 100 lines of dmesg while restarting the network. First restart the network-manager using the command above and then run the below command to get the last 100 lines. dmesg | tail -n 100 and post the output by editing your question. Also, post the last 100 lines of /var/log/messages just after restarting the network-manager

Thank you for your answer. I followed your advice yesterday and the network manager was indeed running (active).
There was a line of code stating a "fail" when I ran the "nework-manager status" command:
"failed to enumerate oFono devices: GDBUS.Error:org.freedesktop.DBus.Error.Serv



Not sure if this will bring any clarity for the outstanding issue, but hope it can help as the computer states the wireless connection being "out of range".
I did try to enable the Wifi through a slide button, but the system did not allow me to do this.



Unfortunately, I am really lost on how to resolve this. I'll be appreciated for any further suggestion/advice.
Thank you.

  • When an error occurs always read your logs with dmesg | tail -20 or journalctl --follow, Then add grep for specifics or egret for a range to narrow down your issue, as in journalctl --follow | egrep "error|corrupt|missing"

  • Used command above. The result was "gdbus COMMAND --help". Tried dmesg command as well but not sure what to look for as I am not savy at all with coding. I will appreciate any further advice on how to resolve this.

pylint3 and pip3 broken

How to enroll fingerprints to Ubuntu 17.10 with VFS491

Image
Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
