I have been using Ubuntu 10.04 since beta 1 and it has been quite stable until this week.
Yesterday on my laptop openoffice simply topped launching, running oowriter from the terminal did not reported any error but nothing happened. I was in a rush to finish a job so I was unable to debug the problem further so I simply rebooted.
During boot the root filesystem was found corrupted, the graphical boot just kept looping changing the message on the screen from "Checking disk blah blah" to "key X por blahblah". I was unable to do recovery, next step, reboot in recovery mode.
Still not good, now it was just looping on the text console, I was unable to read the output.
Another reboot, this time I kept pressing the key that was supposed to bring the recovery console, this time I was able to get into the recovery shell after some iterations of the message loop. I was able to run fsck on the root filesystem and successfully boot.
Today I have booted my desktop (also running Lucid), was about to do some draft html for a status page, decide to install "quanta" for it.
During the install I just got a white screen with X hard locking, well time for another reboot.
I was not sure about the quanta package install status, I have found that quanta was installed by quanta.desktop file was truncated with 0 bytes.
Later I have found that other quanta dependency packages where corrupted
I have filled bugs 559915 and 559915.
Anyone with such bad experiences lately ? I am a bit concerned about having such critical failures on 2 completely different systems.
