The Debian project announced the second update of its stable distribution Debian 8 (codename jessie). This release mainly adds corrections for security problems.
Besides the security fixes this stable update adds a few important corrections to several packages like; apache2, apt, cron, cross-gcc, etc…
“Please note that this update does not constitute a new version of Debian 8 but only updates some of the packages included. There is no need to throw away old jessie CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.” As stated by the Debian project.
Upgrading to Debian 8.2 online is usually done by pointing the aptitude (or apt) package tool to one of Debian’s many FTP or HTTP mirrors.
