“GNU GRUB version 1.97″beta 4 [ Minimal BASH-

Zarrelli il mercoledì, 22 Febbraio, 2012

Today I was updating an Ubuntu 9.04 virtual machine to 12.04. I went successfully to the 10.04 but after the 11.10 upgrade, at the reboot I had the following message:

“GNU GRUB version 1.97″beta 4 [ Minimal BASH-like line editing is supported.For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device/file completions]

sh:grub>

Awkward! Couple of Google queries and I ran into help.ubuntu.com, where I found this pretty nice solution:

ls
set prefix=(hd0,1)/boot/grub
set root=(hd0,1)
set
ls /boot
insmod /boot/grub/linux.mod
linux /vmlinuz root=/dev/sda1
initrd /initrd.img
boot

Give this commands on Grub command line and keep in mind that I’m using sda1 (sda=hd0 | partition=1) and both /root and /boot are on the same partition.

As the system boots, login and issue the following command as root:

grub-install /dev/sda
update-grub

Then reboot. The system should boot up fine now!

ERROR Could not initialize NSS on Debian x86_64

Zarrelli il martedì, 21 Febbraio, 2012

Few days ago I felt the need to setup Icedove so I could read my company email messages on my Debian 6.0 x86_64 notebook. Well, since we use Exchange I had to rely on Davmail to exchange emails with Exchange (sorry, I could not resist the joke). Well, as I checked the emails from my work account, Davmail sported the error “Could not initialize NSS”.

Since I am a lazy guy, I checked Google for an answer, you can find it here. I had to make just a little change cause I use a x64 OS:

uname -m
x86_64

Edit the file

/usr/lib/jvm/java-6-openjdk/jre/lib/security/nss.cfg

And in this snippet

name = NSS
nssLibraryDirectory = /usr/lib
nssDbMode = noDb
attributes = compatibility

you have to change the nssLibraryDirectory value to

name = NSS
nssLibraryDirectory = /usr/lib/x86_64-linux-gnu
nssDbMode = noDb
attributes = compatibility

If you have any problems with the nss.cfg file (backup it before you edit it),  you can always find a fresh copy in:

dpkg -S /etc/java-6-openjdk/security/nss.cfg
openjdk-6-jre-headless: /etc/java-6-openjdk/security/nss.cfg
