Linux: Computer immediately restarts after shutdown

Submitted by Druss on Tue, 2020-07-21 02:53

So I have a Xubuntu box, an old PC that was running Windows previously. All is peachy with the Linux install bar one thing: every time I shutdown the system, it shuts down fine, but immediately restarts again. This wasn't happening with Windows and appeared to be an issue particular to Linux or Ubuntu.

Freeplane hangs in Kubuntu 18.04

Submitted by Druss on Mon, 2019-03-11 17:58

Freeplane, a fork of the mind-mapping program, Freemind, works really well. Except for the fact that in my (K)Ubuntu installation, it sometimes hangs in the middle of editing a node. Once it becomes non-responsive, the only fix is to kill the process and restart the program. The version of Freeplane in Ubuntu 18.04 is 1.6.13. However, the current version (March 2019) of Freeplane is 1.7.7. So, it's highly possible that upgrading Freeplane to the latest version will fix this issue.

Upgrading the Linux kernel in Kubuntu 14.10 from 3.16 to 3.19

So I've had a graphics issue with my Kubuntu box which relies on an Intel motherboard. While I was hoping to put off the fix until the next version of Kubuntu (out in April), the display bug was getting to be really annoying. I therefore decided to upgrade to the latest kernel immediately.

Set the timezone of a Debian/Ubuntu server from the command-line

Submitted by Druss on Mon, 2014-08-25 19:34

Setting the timezone of an Ubuntu (14.04, Trusty) or Debian (7, Wheezy) server from the command-line is simple. Just run dpkg-reconfigure tzdata and follow the on-screen prompts. However, if you are running an unattended installation, you might want to avoid interactive prompts and just gets the job done. To do this, simply run

$ sudo ln -sf /usr/share/zoneinfo/America/Anchorage /etc/localtime

Browse through /usr/share/zoneinfo/ to locate your timezone.

Disable pop-ups for an unattended/non-interactive apt-get install in Ubuntu/Debian

Submitted by Druss on Mon, 2014-08-25 17:37

So, here I was writing a script that would automate the installation of a package in Ubuntu 14.04 and all was going swimmingly. Until I ran it. You know how some apt-get installs sometimes involve a technicolor pop-up that asks you for stuff? Well, those pop-ups interrupted my script which didn't proceed further. After much digging, I found that there are a couple of solutions for this:

bash: cannot set terminal process group (3987): Inappropriate ioctl for device bash: no job control in this shell

On a new Ubuntu 14.04 (Trusty) LTS server, I ran into the following:

$ su -c /bin/bash foo
bash: cannot set terminal process group (3987): Inappropriate ioctl for device
bash: no job control in this shell

However, the su procedure worked and I was logged in as user foo.

Drupal XMLSiteMap: public://xmlsitemap/ not found or not writable

Submitted by Druss on Fri, 2014-04-11 00:48

I ran into the following error (or something like it) while setting up Drupal's xmlsitemap module:

public://xmlsitemap/lOtsOfgoBBlDegOOk not found or not writable

This is as expected some kind of permissions issue. Why the module can't sort this on its own, I do not know. As with everything Drupal, clear the cache first to see if that fixes things. It sometimes does. If not, you will need to get your hands dirty on the commandline (if linux):
