Updated Canonical has overcome a late-breaking bug in Lucid Lynx to deliver the next installment of Ubuntu Linux.

Ubuntu 10.04 was released to the web mid morning Pacific time on Thursday, the day originally scheduled. Final code can now be downloaded for Ubuntu 10.04 Desktop, Server and Netbook editions.

The release came after company chief executive Jane Silber had told The Reg via email the release was not delayed as engineers raced to fix a bug.

"There was a late respin to improve the performance of Ubuntu under a dual boot scenario, but that will not cause a delay in the release," she said.

The bug affected dual-boot users and would not let the other operating system appear in the GRUB menu. It was decided a respin was preferable to having users try to implement their own work-around.

"Installing the available updates and rebooting will fix this issue. However, it was determined the day of the release that this is not an optimal solution for new users or those not connected to the Internet," the Ubuntu Wiki said.

Earlier, it had been had reported that the respin had delayed Thursday's delivery.

The GRUB bug was the second problem found in Ubuntu 10.04 this week. A "major" X-Server memory leakage bug that "causes the computer to get slower and slower over time" was identified Monday and fixed. ®
