I installed RabbtVCS on Ubuntu GNOME 14.04 Trusty Tahr from the Ubuntu repositories (rabbitvcs-nautilus) and it did not integrate into Nautilus. It also seemed to cause other strange effects (mouse wheel not working any more, …?).
Installing the latest version from the RabbitVCS PPA fixed all this:
sudo add-apt-repository ppa:rabbitvcs/ppa sudo apt-get update sudo apt-get install rabbitvcs-nautilus3
Hope this saves somebody half an hour figuring out how to solve this 😉
Today my mythTV based media homeserver suddenly would not automatically shutdown any longer after a kernel update.
Logs by mythbackend (/var/log/mythtv/mythbackend ) that triggers the shutdown looked like this:
localhost mythbackend[1674]: I Scheduler scheduler.cpp:2729 (CheckShutdownServer) CheckShutdownServer returned - OK to shutdown localhost mythbackend[1674]: N Scheduler scheduler.cpp:2814 (ShutdownServer) Running the command to set the next scheduled wakeup time [...] localhost mythbackend[1674]: E Scheduler scheduler.cpp:2820 (ShutdownServer) SetWakeuptimeCommand failed, shutdown aborted
So I ran the SetWakeupTime command myself and go this problem:
/sys/class/rtc/rtc0/wakealarm: No such file or directory
And in fact the file was missing.
I tried to shut down the pc completely (manually) and start it again. But it wouldn’t power off, it just freezed with the shutdown bar on the screen. Pressing the power button once (only short, not holding it) made the PC power off.
So this looked like some big ACPI problem.
After some more search, I found this in the syslog (/var/log/syslog):
localhost kernel: [ 0.000000] ACPI: no DMI BIOS year, acpi=force is required to enable ACPI localhost kernel: [ 0.000000] ACPI: Disabling ACPI support
So no ACPI support explains why wakealarm and shutdown is broken.
I am wondering why this happens suddenly after a kernel update (I have not changed my BIOS or something and ACPI was perfectly working before).
Forcing ACPI solved the problem.
If you use grub2, this is how to do it:
Open /etc/default/grub (e.g. “sudo nano /etc/default/grub”) and update this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Into this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
Save the file and update the grub configuration:
sudo update-grub
Then restart and you’ll be done.
sudo shutdown -r now
I hope this could help somebody.
I recently had to recreate the SSL certificate of a Zimbra server and surprisingly it was not as easy as the documentation looked like, so I’d like to document how it is done and make comments on some difficulties that might come up.
So this is how it is done (on a Ubuntu Server running Zimbra Network edition 6.0.16 GA):
su - zimbra
sudo /opt/zimbra/bin/zmcertmgr createca -new sudo /opt/zimbra/bin/zmcertmgr deployca sudo /opt/zimbra/bin/zmcertmgr deploycrt self
/opt/zimbra/bin/zmcontrol stop /opt/zimbra/bin/zmcontrol start
So the difficulties I had and some remarks:
sudo zmcertmgr createca -new
Seems I am not the only one with this problem. The zmcertmgr command is white-listed in /etc/sudoers so you should normally not be asked for a password. Run the following command to edit /etc/sudoers (do not edit it in any other way!)
visudo
So make sure in this file the following line is included:
%zimbra ALL=NOPASSWD:/opt/zimbra/bin/zmcertmgr
The % at the beginning seems to belong there. Note that the zimbra wiki has typo (zmvertmgr) in this line.
But although I had this line in there, sudo kept asking me for the password. So what finally worked was invoking zmcertmgr with the complete path (as done above).
Update: It seems I had a typo in here myself. Make sure it is “zmcertmgr” and not “zmzertmgr” 😉
Thanks to the comment by erolha!
sudo zmcertmgr deploycrt self -new
I got this error:
Can't deploy cert for -new. Unknown service.
Without -new (and the complete path), it went through well.
I hope I could help some of you that run into one of these problems.
Clonezilla is a fine tool to backup/restore/clone partitions or drives. It is very powerful, can handle both Linux and Windows partitions and so on. If you do not know it, you should really give it a try. It is really free software (open source), which means it is also free to use for commercial purposes.
By the way, if you want to backup/restore images of Windows partitions/drives, I’d also recommend DriveImage XML which is also very powerful yet simple (only free for private use). Windows 7 has also built-in backup and imaging tools, which you can give a try. But this post is about Clonezilla.
One important feature that Clonezilla does not offer out of the box is browsing images to restore single files. You can only restore complete partitions or drives.
But there is a way around this, which is discussed in this forum thread, although not perfect as it requires lots of time and disk space as well.
The basic approach is to convert the whole image into a (probably huge) img-file that can be easily mounted. In the forum post linked above several different commands are discussed depending on your image file.
Here I’d like to show you what worked for me.
In my case, the file was compressed using gzip and it was an image of a linux partition (ext3). I used Ubuntu Linux to mount the image. The steps I took:
touch /dir-to-new-image/partition.img
You should have at least as much free disk space as the size of the image there.
sudo cat /dir-to-images/partition.ext3.ptcl-img.gz.* | sudo gzip -d -c | sudo partclone.restore -C -s - -O /dir-to-new-image/partition.img
(This is one line. Note the minus after -s. I overlooked it when I tried this first.)
This will take some time, dependent on how big the image and how fast your drive(s).
There are other commands in the forum thread for NTFS images and other compression formats.
sudo mount -o loop -t ext3 /dir-to-new-image/partition.img /mnt
Thanks a lot to all posters of the forum mentioned above for these hints, especially bfitzhugh, nutria007, ttguy and gaebriel!
P.S.: It’s always good to have a (recent) backup 😉 One drive of mine just crashed after about two years in operation, so I know what I am talking about…
Think about what pain it would be if the drive of your laptop / desktop would crash just right now. If you get a bad feeling thinking about this, you should make a backup now.
When selecting a language at login, Horde webmailer does not change the language?
Here is what I found out what helps:
On Debian, run the following command:
dpkg-reconfigure locales
Then select the correct languages. I had only selected the UTF8 languages for German, but Horde needs the following ones:
de_DE ISO-8859-1 de_DE@euro ISO-8859-15
If you have the problem with another language, select the corresponding language.
On Ubuntu, the chosen languages are stored here:
/var/lib/locales/supported.d/
I had a file named “de” in there where my chosen languages where listed and I added the ISO-versions above. You can find all supported languages here:
less /usr/share/i18n/SUPPORTED
On Ubuntu, after you included your languages, you have to run the following command:
dpkg-reconfigure locales
Afterwards, you need to restart apache:
apache2ctl -k graceful
That’s the smoothest way. In case it does not work, use one of those:
apache2ctl restart service apache2 restart /etc/init.d/apache2 restart
Now refresh Horde and everything should work.
Another problem is the following: if you chose a language in your Horde settings (login, Global Options, Locale and time, Select your preferred language), this overwrites the language you chose on login. So select “default” there to be able to chose language on login.
Hope this helps somebody.
