- | * | + | * You need to install the [http://maemo.org/packages/view/easy-deb-chroot/ easy-deb-chroot package]. It can be found in the [[Extras]] repository. There may be a newer version in the [[Extras-devel]] repository. (Enabling Extras-devel is a dangerous area and you should disable it as soon as you are done installing Easy Debian, but Easy Debian is rather safe and it is optified.) |
- | + | * Once installed several new shortcut icons will be available on the applications menu. You will need to first run the one called "Debian Image Installer". A terminal program will open and ask you where to place the image file (after decompression it will be a 2 GB file), either on the [[Nokia N900|N900's]] built in storage (under MyDocs), or on an external MicroSD card (if available). That will start the download of the compressed image (about 300 MB) and eventual extraction of the image file. It may take more than 15 minutes to download if you have fast Internet connection, and another 30 minutes or more to extract it on your tablet. Make sure that there are no other processes running and that the extraction is not interrupted. | |

** You can check for a successful download and extraction by typing<pre>ls -l /home/user/MyDocs/debian*</pre> in [[terminal|XTerminal]]. The compressed image name has the ending .img.ext2.lzma; when decompressed the file name ends in .img.ext2 and it should have a file size of exactly 2147483648 bytes. | ** You can check for a successful download and extraction by typing<pre>ls -l /home/user/MyDocs/debian*</pre> in [[terminal|XTerminal]].

* This step is an alternate way to do the previous step: You can manually download the image file from [http://qole.org/files//debian-m5-v3e.img.ext2.lzma here]. Afterward you will have to copy it into <code>/home/user/MyDocs/</code> or into <code>/media/mmc1/</code> depending on whether you want it installed on the internal storage or on a removable storage. Then, when you run "Debian Image Installer" it will detect that you already have the file and proceed to extract it and set it up for you. For detection of your already placed debian* file stated above, the Debian Image Installer still need to connect to the internet for file checking purpose. If you have a faster computer with [http://www.7-zip.org/ programs] to unpack [[:wikipedia:Lempel%E2%80%93Ziv%E2%80%93Markov_chain_algorithm|lzma]]-compressed files, you may also skip the Debian Image Installer by copying the uncompressed file by USB to the <code>/home/user/MyDocs/</code> folder. | * This step is an alternate way to do the previous step: You can manually download the image file from [http://qole.org/files//debian-m5-v3e.img.ext2.lzma here].

This will get your browser installed, but it will then complain (if started from command line) about the lack of libesd0 and libcurl3. You can install both of these, also from squeeze sources, upon which it will start without complaining. Also, if you've been testing it as root, then you'll want to "chown -R user /home/user/.cache/chromium" and "chown -R user /home/user/.config/chromium" for it to work properly as "user". | This will get your browser installed, but it will then complain (if started from command line) about the lack of libesd0 and libcurl3.

Debian Wheezy takes up more space than Squeeze. If you want to enlarge your image file, the maximum file size that you can support on a FAT32 partition is 4GB minus one byte, or 4,294,967,295 bytes. Beyond that, you'll have to use a dedicated partition. | Debian Wheezy takes up more space than Squeeze.

So, without harming portability, we can increase our image file by 1GB (almost) and then grow the file system to fit it. To increase the image size, first, concatenate 1GB of zeroes onto the end of the file: | So, without harming portability, we can increase our image file by 1GB (almost) and then grow the file system to fit it.

Note that the ">>" is critical here, meaning append the zeroes to the end of the file; accidentally use ">" and you'll overwrite the image. The command will "fail" with an error when you hit 4GB on a FAT32 filesystem, but, don't worry, that's because we hit the maximum file size before we ran out of zeroes. Our image file will still be the desired maximum possible size. Now, we need to unmount and remount the image, in order for the loop mount to pick up the larger "device" that we just created. This is as simple as running the Close Debian script, then restarting Easy Debian via Deb Chroot (or sudo debian). | Note that the ">>" is critical here, meaning append the zeroes to the end of the file; accidentally use ">" and you'll overwrite the image.
