The default setup for Munin in Debian seems to miss some packages for the mysql_ plugin.
/usr/share/munin/plugins/mysql_ suggest
will give you
Missing dependency Cache::Cache at /usr/share/munin/plugins/mysql_ line 716.
The solution was easier than excpected:
aptitude install libcache-cache-perl
and done.
Onliner found here to reset a user password for the OpenVZ Web Panel (admin in this case)
ruby /opt/ovz-web-panel/script/runner -e production 'user = User.find_by_login("admin"); user.password = "admin"; user.save(false)'
A new Ubuntu version, a new game.
I guess it is the first time I have my notebook running in optimus-mode!
I’ve not fully checked it, but Ironhide looks promising and seems to work so far.
Having problems installing Ubunut 11.10 via USB “An attempt to configure apt to install additional packages from the CD failed”
Use this:
sudo rm /usr/lib/ubiquity/apt-setup/generators/40cdrom
I’ve setup a fresh vServer-environment for a few test and developmentmachines to play around with.
When I tried to install gitolite via aptitude everything fails and the whole system is near an explosion:
root@git:~# aptitude install git-daemon-run runit
The following partially installed packages will be configured:
runit
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.
/bin/sh: /usr/bin/apt-listchanges: not found

A package failed to install. Trying to recover:

Maybe this can help someone, because below a bunch of mails on the Debian mailinglist there is a bugreport with a workaround:
If you try to install the runit package, and after the failure remove the SV inittab entry, edit /var/lib/dpkg/info/runit.postinst and remove the 'kill -S HUP 1', and then run 'dpkg --configure runit', does the installation succeed, and if yes, is a runsvdir program running?
Yes it does! At least for me.
You’ve setup your own Gitorious and lost your password? No, problem!
SSH your way to your box and change into the gitorious-directory (mine is /var/www/gitorious)
Fire up the console
env RAILS_ENV=production ruby script/console
on sudo-systems (like Ubuntu)
sudo env RAILS_ENV=production ruby script/console
and then type in the following commands
@user = User.find_by_login("yourusername")
@user.password = "yournewpassword"
@user.password_confirmation = "yournewpassword"
@user.save
The final output should be “true” and you’ll be able to login into the account with your brand new password. Yay!
Holy Moly!
I just had a hard fight with my brand new Thinkpad T420s, trying to get the NVIDIA graphics to work.
After installing the properitary nvidia drivers via ubuntu unity stopped working after the restart and no nvidia driver was active.
The solution, after all, was pretty simple:
It seems that there is currently no linux-support for nvidias optimus-technology.
I’m currently writing on my thesis and had the problem that OO is crashing all the time for unknown reasons. After I did some research I came to the following conclusion:
Screw it!
Remove the OO-packages which ship with ubuntu and install a fresh vanilla version (follow this)
I had no crash since that change and everything works pretty smooth.
I just had the case that I needed to rename all old .html-files into .php for a large website.
This little command did it for me
find . -name "*.html" -exec rename -v 's/\.html$/\.php/' {} \;
Install first:
than the install will work smoothly =)
