Installation of Lubuntu 14.04 fails on PowerPC computer

[August Karlstrom]

At the beginning of the installation of Lubuntu 14.04 Alternate PowerPC on an iMac G3 500 I get the error message

mount: can't find /run in /etc/fstab

I have a working installation of an old (no longer supported) version of Lubuntu on the harddrive so I don't think it is related to hardware failure.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1341334

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I tried to upgrade the current installation with the `do-release-update' command but unfortunately it failed and now I don't have a working installation anymore. I could reinstall the old version of Lubuntu and the run `apport-collect' but currently I don't have access to the computer in question.

[Joseph Salisbury (jsalisbury)]

Is the iMac G3 process non-pae? If so, that would explain why Precise and older can install without an issue.

[August Karlstrom (fusionfile)]

@jsalisbury: I don't think it is, the CPU is a PowerPC 750.

[August Karlstrom (fusionfile)]

What more information do I need to provide before we can change the status from "incomplete" to "new"? By the way I recently installed Debian 7.6 on the computer in question and it went smoothly.

[Chris Bainbridge (chris-bainbridge)]

@Joseph the G3 is a non-x86 processor - it uses a different kernel that does not require PAE.

for me the installation went well - PowerMac G5 , 7.3 , DualProcessor and Nvidia 5200 FX.

After installation , boot process with various results - striped colours , black screen, etc.

What helped me was to edit yaboot.conf

following this guide here

http://www.mintppc.org/forums/viewtopic.php?f=14&t=1289

so i was able to boot up and login normally and use computer.

but after "apt-get update"and "upgrade" i had to download many packages and afterwards i experienced kernel panic

kernel that was installed was number 3.13.

Installer used was 14.04 LTS Alternate Installer for PowerPC
