Not sure what the issue is. But when I
sudo apt-get install mysql

E: Unable to locate package mysql
I get the same error when I try and install nginx.
Have a raspberry pi 3 b+. sudo apt-cache search nginx turns up no results
First you should update package list:
sudo apt-get update
then:
sudo apt-get install mysql-server nginx
I already tried doing the update, but nothing happened. Then I ran sudo apt-get dist-upgrade and now I am getting nginx and mysql-server.

I am trying to install MySQL on a Raspberry Pi 3. Currently I have Apache and PHP installed. I now need to install MySQL but when I do sudo apt-get install mysql-server php-mysql -y, I receive an error telling me that there is no such package:
E: Package 'mysql-server' has no installation candidate
Complete output:
pi#raspberrypi:/var/www/html $ sudo apt-get install mysql-server php-mysql -y

Package mysql-server is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
mariadb-server-10.0
E: Package 'mysql-server' has no installation candidate```
I guess using MariaDB fixes my issue.
sudo apt install mariadb-server php-mysql -y
I'm trying to un-install grafana 4.6.3 from Ubuntu 17.10, but is not possible. So far i have tried
sudo apt-get remove grafana , sudo apt-get remove --auto-remove grafana
and says Unable to locate package grafana.
Also tried to install it again from ubuntu software in order to unistall it properly but then pops me up an error message says: Unable to install grafana snap "graphana" is already installed. I installed it first time from ubuntu software.
What can i do to un-install it?
Have you tried dpkg?
sudo dpkg --remove --force-remove-reinstreq <packagename>
If apt won't remove it try using dpkg.
You could also try and clean up your apt utility.
sudo rm -rf /var/cache/apt/archives/<package_name.deb>
sudo apt-get autoclean
sudo apt-get update
sudo apt-get upgrade
I have used the instructions from the docs
after this command:
sudo apt-get install -y mongodb-org
I get this warning:
WARNING: The following packages cannot be authenticated!
mongodb-org-shell mongodb-org-server mongodb-org-mongos mongodb-org-tools mongodb-org
E: There were unauthenticated packages and -y was used without --allow-unauthenticated
Its instruction to start and test gives the following:
sudo service mongod start
cat /var/log/mongodb/mongod.log
cat: /var/log/mongodb/mongod.log: No such file or directory
As I mentioned in the comment, you could solve the problem by bypassing the gpg signature checks of apt using :
sudo apt-get --allow-unauthenticated install -y mongodb-org
You might want to have a look at more configuration options in detail along with right practices of using this appraoch here : https://askubuntu.com/questions/74345/how-do-i-bypass-ignore-the-gpg-signature-checks-of-apt
The mongodb docs have a great page on installing the latest mongo on Ubuntu. You can find it at: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/
I'd recommend uninstalling mongodb and following the instructions on the previously mentioned page.
I've updated my Ubuntu 14.04 to the latest 15.04. Since then Mongo failed to run. can run the command mongo and it'll advise the version and so on but server will not run: sudo service mongod start as normal.
When I ran: sudo apt-get install -y mongodb-org it failed with the error in the screen shot below:
I completely purged mongo and re-installed, followed the instructions from here. However when I ran sudo apt-get update I noticed the below packages were 404'ing. See Screen shot below.
If anyone could shed any light on this would be great?
Following instructions from this page page http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
but with slighty changed second step 2. Create a list file for MongoDB:
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
I put trusty (code name for Ubuntu 14.04 LTS) instead of $(lsb_release -sc) which issues vivid as codename for 15.04
I see now that #Nail Lonergan already commented echo path change...
There is currently no build available for Ubuntu 15.04. Check this page for all builds: https://www.mongodb.org/downloads#development
After having heaps of issues, finally this is how I installed it,
Ubuntu 15.04
apt-get update
apt-get dist-upgrade
apt-get install -y mongodb
sudo apt-get install upstart-sysv
sudo service mongodb status
if not running
sudo service mongodb start
Install PHP Driver
sudo apt-get install php5-dev
sudo apt-get install build-essential
sudo pecl install mongo
https://sonnguyen.ws/install-mongodb-mongo-php-in-ubuntu/
sudo apt-get install mongodb
ps -ef|grep mongo
sudo pecl install mongo
sudo apt-get install php5-dev php5-cli php-pear
