[SOLVED] How to fix breaking/cracking audio on MSI X320 or similar Poulsbo chipset based laptops on Ubuntu / Linux Mint

[SOLVED][PHP PEAR] How to fix the error 'could not extract the package.xml file' and 'Download of "pecl/uploadprogress" succeeded, but it is not a valid package archive', when trying to install PECL uploadprogress using PHP PEAR on Ubuntu 14.04 Trusty

[SOLVED] Error when installing modules in Drupal 7 from admin/modules/install - Exception: Invalid checksum for file...calculated, 0 expected in Archive_Tar...line 635 of modules/system/
