无法在ubuntu 16.10上再次安装php5.6-curl。 ppa被添加。

Im trying to install php5.6-curl package. It was installed before but I did some stuff with manual build of curl, so I had remove php5.6-curl package from system. I also ran apt autoremove after this operation.

So, after successfull build stuff I was trying to call apt-get install php5.6-curl and it showed me this.

dirst@dirst-machine:~$ sudo apt-get install php5.6-curl

This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php5.6-curl' has no installation candidate

You can be sure that ppa:ondrej/php5-5.6 is installed on my ubuntu as php5.6 is present in the system and php5.6-curl package had been isntalled before.

I also tried to add ppa again and ran apt-get update. Im not sure what this messages means. yakkety InRelease

Next what I tried is to check php extensions available with apt-cache search php5.6. There is no php5.6-curl but I know it should be there.

dirst@dirst-machine:~$ apt-cache search php5.6
php-igbinary - igbinary PHP serializer
php-msgpack - PHP extension for interfacing with MessagePack
php-ssh2 - Bindings for the libssh2 library
php-xdebug - Xdebug Module for PHP
php5.6-opcache - Zend OpCache module for PHP
php5.6-mysql - MySQL module for PHP
php5.6-json - JSON module for PHP
php5.6-common - documentation, examples and common module for PHP
php5.6 - server-side, HTML-embedded scripting language (metapackage)
php5.6-mcrypt - libmcrypt module for PHP
php5.6-readline - readline module for PHP
php5.6-gd - GD module for PHP
php5.6-xml - DOM, SimpleXML, WDDX, XML, and XSL module for PHP
php5.6-cli - command-line interpreter for the PHP scripting language
php5.6-mbstring - MBSTRING module for PHP
php5.6-ldap - LDAP module for PHP
libapache2-mod-php5.6 - server-side, HTML-embedded scripting language (Apache 2 module)
php-memcached - memcached extension module for PHP, uses libmemcached

I also launched clean ubuntu 16.04 in the cloud and tried to do same actions. - Install php5.6, php5.6-curl. - Remove curl and then build it manually - Install php5.6-curl again

All worked like a charm. And list of the extensions is way too bigger when I execute apt-cache search php5.6 on cloud ubuntu.

I dont't know what am I doing wrong, Im not really strong linux guys, so I have no Idea what is going on. Please help.

    guys from askubuntu helped. Thing was obvious. Just change ppa repo to xenial from yakkety and it works. As yakkety doesn't have php5.6-curl in repo.
