General Support / grub errors on ubermix 2.21
« Last post by ubermonki on May 16, 2015, 05:53:30 PM »
e: grub-pc: subprocess installed post-installation script returned error exit status 1

I just installed latest ubermix-64 on a Dell Dimension 5150. I keep getting package errores related to grub. I'm guessing they have something to do with the partitions setup for the ubermix recovery system, but I get the error whenever I update, add or remove packages. Is this a real problem, the system boots just as it should, or is there something I can uncheck in synaptic to keep the error from happening? Thanks

Q&A / Cryptographic Hash Values (MD5, Sha1, etc) for ISO is Missing
« Last post by PaulJRichardson on May 09, 2015, 06:11:59 PM »
The ISO image for your alternative (non-USB) install from CD, does not list an MD5, Sha1, etc.

However, most of the downloads DO provide a checksum (or crypto hash) for integrity of downloads.
I actually had a 'bad' download once from one of your images, on another file, relative to that published for the download -> which motivates me to ensure this gets done, for the sake of others ;-)

The ISO I am referring to, is NOT listed at the primary download page (as it is the unrecommended/alternative CD install ISO):

The ISO is listed on this page:
FileName: uber-v2-32-install.iso

Here is the direct download link:

Less important, but perhaps potentially also time-saving, would be another couple minor grammatical/naming repairs, which I've identified below:

OLD (Invalid) Name: Image Writer for Windows
OLD (Invalid) Link:

NEW (Correct) Name: Win32 Disk Imager
NEW (Correct) Link:

... so, now at long last, here (below) are the values that I got, after the completed download for this ISO:

FileName: uber-v2-32-install.iso
MD5: b05b95560d5d1743a3fc3f5400e1d482
SHA-1 [160]: de7a4f2f8fdabb4d952c643aee2a742bf6d2a8b4
CRC32: 26cc3605
SizeHash-32: 0c97d800

Which you may want to publish on the page linking to that file.

Probably has something to do with the script running as root and a missing environment. Instead of sudo, try:

su -c "gsettings set org.gnome.desktop.wm.keybindings show-desktop \"['']\"" - user

Should work better.
I have added a line to our script to change some keyboard shortcuts.
If I open a terminal and run
Code: [Select]
sh .network-autostart the changes are made. However on boot/network-disconnect-reconnect the changes don't get made.

Here are the two lines:
Code: [Select]
sudo -u user gsettings set org.gnome.desktop.wm.keybindings show-desktop "['']"
gsettings set org.gnome.desktop.wm.keybindings show-desktop "['']" #this is optional but I included it for testing purposes

Other parts of the script work fine on boot. I am thinking it has something to do with how .network-autostart is called. Any thoughts?

This soft it's amazing. It's was developed between teachers, and Computer Science professionals. Kids develops games in 2-3 hs, and it's working great, lots of users adopting it.
It's a great way to introduce kids into programing.

Ubermix is a x68 based ubuntu distribution. If there is a large base of users requesting it, maybe Jim will port it.
But using a system like ubermix is not against the raspberry pi "philosophy" ? It's a computer to build, test, reconfigure, and to analiyze multiple hardware -  software configurations.
Also, RP 1 is very hardware limited. Ubermix 2 or 1.5 will be too slow. I read some reports on RP2 being just good for normal use, but i don't know.

OK, Ubuntu has been released for the Raspberry Pi 2

What are the chances of getting Ubermix for the Raspberry Pi 2?
Not sure what package is causing this but in preparing our 2.x master for reimaging this summer I grabbed all updates. 

On reboot I get

"an error occurred while mounting /ro"

"Press S to skip mounting or M for manual recovery"

I ended up moving /opt to /home/opt and replacing /opt with a symlink to /home/opt.  Same treatment for /var/cache.  moved to /home/cache.
