No releases available for package

Question

I'm trying to install some pear packages such as gnupg in a Ubuntu OS in virtualbox, but if i use sudo pecl install gnupg, it throws

No releases available for package "pecl.php.net/gnupg"
install failed

It is not only happening for gnupg, but for all pear packages. But i couldn't identify what exactly the issue is. The same command is working in my another virtual machine. So i'm really confused. Please help.

Note:

PEAR Version: 1.9.4

This is what the pear configuration (using pear config-show) shows,

When i use pear clear-cache, it shows,

Directory /tmp/pear/cache not found.

For the commands pear update-channels and pear upgrade, i got,

Answer 1

Have you tried entering this before?

pear clear-cache
pear update-channels
pear upgrade

Answer 2

I had this problem with pecl and oci8. Resolved by setting the proxy to get through our firewall:

sudo pear config-set http_proxy http://username:[email protected]:port

Perhaps this is your problem?
