Unable to run couchbase on ubuntu 16.04 - virtual-machine

I tried to install all the couchbase using all the methods provided in the couchbase website documentation but still facing errors.
The Debian file is loading continuously and if I'm trying to install it using terminal, I'm getting the following error.
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

First check if there is a dpkg process running, ps afx|grep dpkg
If thats the case, kill it with sudo killall dpkg
Remove the lock file with sudo rm /var/lib/dpkg/lock
That should do the trick

Error running outguess on Linux terminal in windows

So far I was able to get outguess installed on my Ubuntu distribution running under WSL by running sudo apt-get update and then sudo apt-install -y outguess. Both commands worked fine. After, I tried running outguess -r input.jpg output.txt and the error Can't open input file 'input.jpg': fopen: Permission denied shows. I've looked on google and a few forums but there is no definitive answer to this. Can anyone help?

Unable to run npm commands with sudo

I've recently installed the balena-cli package via npm (which itself has been installed using nvm) which works fine when accessed from my default user.
However whenever I try to access npm, nvm or balena-cli using sudo they all print the following error
$ sudo npm
sudo: npm: command not found
$ sudo nvm
sudo: nvm: command not found
$ sudo balena
sudo: balena: command not found
I tried using sudo chown on all 3 but to now avail.
Basically, none of the Node related functions can be accessed using root.
Any suggestions on how to resolve this, perhaps by the use of environment variables?
As a stop gap, I found out that running the same command after switching to root works fine with the following command;
$ sudo -s
However, since it's a stop gap, it would be great to find a way to run the same commands without switching back and forth between root.
Basically once do check that have you flashed Balena image correctly and then check the network permissions and login to Balena with root and run commands with su instead of sudo then your issue might clear.

Permission Denied while installing Node on WSL using NVM

I tried to install Node LTS on WSL using NVM.
While I successfully installed nvm, Node installation using nvm install --lts made some errors:
mv: cannot move '/home/anesin1109/.nvm/.cache/bin/node-v10.15.3-linux-x64/files/bin' to '/home/anesin1109/.nvm/versions/node/v10.15.3/bin': Permission denied
mv: cannot move '/home/anesin1109/.nvm/.cache/bin/node-v10.15.3-linux-x64/files/include' to '/home/anesin1109/.nvm/versions/node/v10.15.3/include': Permission denied
mv: cannot move '/home/anesin1109/.nvm/.cache/bin/node-v10.15.3-linux-x64/files/lib' to '/home/anesin1109/.nvm/versions/node/v10.15.3/lib': Permission denied
mv: cannot move '/home/anesin1109/.nvm/.cache/bin/node-v10.15.3-linux-x64/files/share' to '/home/anesin1109/.nvm/versions/node/v10.15.3/share': Permission denied
I tried to move these files manually, but it also ended with those errors.
Try making sure nothing is accessing the directory. I had this exact issue. I figured out that my VisualStudio Code had the directory open in the WSL which prevented NVM from doing its thing. After closing VS Code nvm install 12 worked fine. Hope that helps.
Please check if your user owns all files in .nvm. You can take ownership recursively with chown -R <user> .nvm. Delete all node versions recursively with rm -rf .nvm/versions/node. Then try again; this process worked for me at least.
problem solved with me when i upgrade the WSL distribution from WSL1 to wsl 2
wsl --set-version Ubuntu 2

Apache doesn't start in AMPPS on Ubuntu

I'm trying to run the Ampps local server 3.8 on Ubuntu. Mysql works good but apache doen't run.
When I type
/usr/local/ampps/apache/bin/httpd
I get
/usr/local/ampps/apache/bin/httpd: symbol lookup error: /usr/local/ampps/apache/lib/libapr-1.so.0: undefined symbol: dlopen
How to solve?
I experienced a similar problem. Firstly you must check is there anything that uses 80 port.
If any you kill that.
Then you backup libapr and then install libs again.
Run following commands:
cd /usr/local/ampps/apache/lib
sudo mkdir backup
sudo mv ./libapr* ./backup/
sudo apt-get -y install libaprutil1 libaprutil1-dev libapr1 libapr1-dev
and try run ampps.

Why localhost's phpmyadmin is empty with no login window?

I installed phpmyadmin following the instructions here. Installation has completed and I have phpmyadmin inside /usr/share/phpmyadmin and has linked to
sudo ln -s /usr/share/phpmyadmin/ /var/www/html/phpmyadmin
But doesn't show anything (the whole page is blank with no login window) when I access to http://localhost/phpmyadmin
What could be wrong?
My os is Ubuntu14.04 and installed Apache 2.4.7.
For those who has similar problem, please follow the steps below.
Please check error at /var/log/apache2/error.log
My error is PHP Fatal error: require_once(): Failed opening required './libraries/php-gettext/gettext.inc' (include_path='.')
So install sudo apt-get install php-gettext
Then restart sudo service apache2 restart.
