After I uninstalled rbenv from Ubuntu, every time I open the terminal I get this message:
The program 'rbenv' is currently not installed. You can install it by typing:
sudo apt-get install rbenv
How should I remove this message?
Part of the rbenv initialization occurs in your ~/.bashrc or ~/.bash_profile (or one of the similar start-up scripts). Typically those lines are at the bottom of the script. Read the above page for more information and what to look for.
Remove those lines that try to initialize rbenv and you should be fine.

(solved, make sure your graphics driver is correct, dont remember which, its from between fake and legacy. Otherwise, reinstall your os, it should fix then)

Question:
When I launch Minecraft pi it shows a black window for a second and closes.
in command line it gives me the error:
failed to add service - already in use?
after command:
sudo minecraft-pi
Try this:
sudo apt-get purge minecraft-pi
sudo apt-get update
sudo apt-get install minecraft-pi
If all else fails why not just play the full version of Minecraft? (Minecraft Java Edition). https://forums.raspberrypi.com/viewtopic.php?t=279135
It's my first time trying to install and using Arch linux, I was trying to install it in VirtualBox in Mac Os mojave, when i did arch-chroot /mnt(after all the configuration), then tried to nano /etc/locale.conf it just printed command not found.
I've already tried with vim or other commands like sudo or apt to install a plain text editor but it's always the same and I also tried twice but nothing changes.
PLEEAAASE, I need help.
In Archlinux you should use pacman -S to install packages
try this :
"pacman -S nano"
you can see more information here:
https://wiki.archlinux.org/index.php/pacman#Installing_packages
You can install it with the Linux kernel etc.
For installing the kernel you use
pacstrap
so just add nano, vim or whatever text-editor you like to use.

I just installed Windows Subsystem for Linux for the first time and downloaded the Debian distribution from the Windows Store.
The first thing I tried to do was use the "mv" command. The second thing was to run "man mv" because I don't remember how to use it. But I received the error:
-bash: man: command not found
It looks like the package I want is called manpages. But I can't install that:
sudo apt-get install manpages
[sudo] password for pi:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package manpages 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
E: Package 'manpages' has no installation candidate
How do I get the man command up and running?
apt update to update the local package lists followed by apt install man-db to install the actual package.
I want to add to elken's answer that apparently, the 'man-db' packages doesn't cover all the manpages. For example, I needed documentation for the C stdio library (fopen, fgets, ...), and for that I had to install 'manpages-dev':
sudo apt install manpages-dev
Apparently there are also some other manpage collections (/different names for them on certain unix distros), see https://superuser.com/questions/40609/how-to-install-man-pages-for-c-standard-library-functions-in-ubuntu
I got an error.
$ valet install
[DomainException]
Unable to determine linked PHP.
install
'which' command returns:
$ which php
/usr/local/Cellar/php70/7.0.6/bin/php
I used Homebrew to instal php7.1 , So I ran this command in terminal
ln -s /usr/local/opt/php71/bin/php /usr/local/bin/php
and everything is done.
if your PHP version 7.x and valet > 2.0.8 update valet
valet stop
valet uninstall
brew install php
composer global require laravel/valet
then valet install
Homebrew creates (or attempts to create) symlinks in /usr/local/bin.
Start by running the following to attempt to create a link.
brew link php70
It'll give you information as to whether or not it was successful. Occasionally permissions are problematic and you can resolve this with
sudo chown -R `whoami`:admin /usr/local/bin
Then try running the brew link command again.
Alternately brew link may give you instructions, or you can use brew doctor to get a report on any problems which exist with your Homebrew installation.
When it's set up properly after running ls -la /usr/local/bin | grep bin/php$ you should see something similar to
lrwxr-xr-x 1 YOURUSER admin 29 10 May 21:40 php -> /usr/local/Cellar/php70/7.0.6/bin/php
I was going to update Laravel Valet from version 1.* to 2 and ran same error like this
Unable to determine linked PHP
The solution was to run
composer global update
before I ran
valet install
This happens when your brew php gets Updated.
If you do brew install php this will work but will install php 7.2 by default.
If you want php#7.1 you have to do brew install php#7.1 this will install php7.1 and now when you restart valet valet restart you might get an error. Unable to determine linked PHP.
To make this work with php7.1 you have make brew link
brew link php71
you may have this error
Warning: php#7.1 is keg-only and must be linked with
to fix this
brew link --force php71
now valet should work on php7.1
I tried all of the suggestions here—and several from elsewhere—before I hit on the solution. This applies to PHP 7.2 (no guarantee for other versions). If you are using the original Larvel Valet, open the file:
~/.composer/vendor/laravel/valet/cli/Valet/Brew.php
...or, if you're using Valet+
~/.composer/vendor/weprovide/valet-plus/cli/Valet/Brew.php
Locate the supportedPhpVersions method. In some versions, it will return an array right in the method:
return ['php72', 'php71', 'php70', 'php56'];
Change this to:
return ['7.2', 'php72', 'php71', 'php70', 'php56'];
In other cases, it'll reference const SUPPORTED_PHP_VERSIONS, and the change will be similar.
Save the file, restart valet, and Bob's your uncle!
I'm trying to install ree-1.8.7 on Ubuntu 11.10, but I get the following:
$ rvm install ree-1.8.7
$ ...
$ ERROR: Error running './installer -a $HOME/.rvm/rubies/ree-1.8.7-2011.03 --dont-install-useful-gems -c --with-readline-dir=$HOME/.rvm/usr', please read $HOME/.rvm/log/ree-1.8.7-2011.03/install.log
$ ERROR: There has been an error while trying to run the ree installer. Halting installation.
If I check the install.log file as suggested, it says that:
GNU Readline development headers... not found
...
Please run apt-get install libreadline5-dev as root
That didn't work because the package is no longer available, so I finally found out about using libreadline from a rvm package. So I install it and run the install again:
$ rvm pkg install readline
$ rvm install ree-1.8.7 -C --with-readline-dir=$rvm_path/usr
I still get the same error even if I run rvm remove ree beforehand.
I'm stuck, what can I do?
UPDATE: I'm still stuck, but I found something that might be useful for others with a similar issue even though it didn't work for me. From the RVM REE page:
NOTE: on any OS, if installation of REE fails and the output file reports missing readline-devel, zlib-devel, and openssl-devel headers AND you are sure that you have read the packages install instructions - or you are otherwise positive that you have the necessary packages installed in a known location - check your PATH environment variable to make sure something like "/usr/lib" is NOT present. See this REE issue for more information. If you don't want to change your PATH variable then this patch fixes the issue in REE 2010.02
I checked my path and all I had that contained /usr/lib was /usr/lib/lightdm/lightdm. My full $PATH is this: bash: /home/michel/.rvm/gems/ruby-1.9.3-p0/bin:/home/michel/.rvm/gems/ruby-1.9.3-p0#global/bin:/home/michel/.rvm/rubies/ruby-1.9.3-p0/bin:/home/michel/.rvm/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games: No such file or directory.
I finally got it working by running this line:
rvm install ree --with-readline-dir=$rvm_path/usr --with-iconv-dir=$rvm_path/usr --with-zlib-dir=$rvm_path/usr --with-openssl-dir=$rvm_path/usr
Running only rvm install ree --with-readline-dir=$rvm_path/usr didn't work, so maybe they all need to be run at the same time.
Note that I ran the following commands some time before succeeding:
rvm head update; rvm reload;
# remove any file from previous failed installations
rvm remove ree
# as suggested in a comment on the question
sudo apt-get install libreadline6-dev
I'm not sure if the libreadline6-dev was necessary, but maybe and it's worth a try if you're having trouble.
