If I go in /cdrom >>> Properties this is what I get:  I search on google how to change permissions and ownership of a mount point, but the usual answer, to use chown command as a root doesn't work  |

What is working now? After rebooting, did you run this again? umount /dev/sdb1

I'd do this: umount /dev/sdb1
echo "/dev/sdb1 /cdrom vfat rw,noatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro,uid=999,gid=999 0 0" >> /etc/fstab
mount /dev/sdb1 Then as a regular user run: echo "Testing Permissions" > /cdrom/permissions.txt If it does not complain about permissions, delete the file: rm /cdrom/permissions.txt and then try starting bitcoin-qt. I restarted the system and now it works, but I still haven't got permissions in /cdrom mount point. I get this: ubuntu@ubuntu:~$ echo "Testing Permissions" > /cdrom/permissions.txt
bash: /cdrom/permissions.txt: Permission denied

Make sure that you close everything that could possible have it open (e.g. gparted)
I have only the browser and the terminal opened. |

I forgot about this.
It's not a directory, but instead it is a mount point.
Please, post your /etc/fstab file contents in here and I (or other user) will tell you what to modify in order to set user and group for the mountpoint.
In options you should add uid=999,gid=999 (the user and group id returned by the ID command I posted earlier).
Then unmount (as root: umount /dev/sdb1) and remount (as root: mount /dev/sdb1).
Luckily this will work as expected, if I'm not wrong.
This is etc/fstab content: overlay / overlay rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0 |

If you'd like to know what's your user's primary group, normally it will be the same name as your username, but you can check this by running as regular user: ~ id
uid=1000(myuser) gid=1000(mygroup) ... or as root: # id myuser
uid=1000(myuser) gid=1000(mygroup) ... I get a syntax error with this code. the commands are without the ~ or # and the second line is just the output. So really, what you should type into the terminal is this where myuser is your username I've just tried to change ownership of /cdrom, but I get this: root@ubuntu:/home/ubuntu# chown 999:999 /cdrom
chown: changing ownership of ‘/cdrom’: Operation not permitted

first shut down bitcoin core.
Then check your permissions. Make sure that you have permission to copy things to /cdrom. Make sure that you have permissions to even move the bin folder.
I don't have permissions to copy things to /cdrom, to move folders or even to create a new folder in /cdrom. I just don't know why... |

When you install, if their is an installation wizard, set the installation directory to a folder in sdb1. If it is just binaries you downloaded, just copy them to a folder on sdb1 and run the program from there.
If I try to change the installation directory, I see the following error message: Cannot obtain a lock on data directory /cdrom. Bitcoin Core is probably already running. No such file or directory.
For bitcoin core specifically, just copy all of the binaries to a folder in sdb1 and run the program from there.
If I try to copy the binaries to a folder in /cdrom I get the following message: The folder “bin” cannot be copied because you do not have permissions to create it in the destination. |

Hi! It's me again  Let me explain what is my new question for you Linux experts. I installed Ubuntu 15.04 on an external hard disk, using the free tool called "LiLi" . Then I booted my Linux distro changing the BIOS settings. The main problem with these kinds of installation is persistence. As a standard, FAT32 allows a maximum persistence of 4GB, but it could be easily changed launching the "gparted" application. And this is exactly what I did: I launched gparted and set HD persistence to 1TB. So this is what I get now:  Anyway, now I wonder how to install Bitcoin Core ( and any other programs ) on sdb1. How can I do this? |

I wonder if that particular ppa isn't updated very often, if that's why the dependencies couldn't be installed (perhaps because newer versions are already installed on your system or something along those lines). Anyway, I'm glad you got it figured out.
I personally performed a clean Ubuntu 15.04 installation. Then, I replicated the same steps that HardcoreSuperstar did, and I did not have that dependencies problems. The PPA is updated in each bitcoin-qt revision, If I'm not confused. I would like to know if you are able to install any other package: Try doing: apt-get install <some-package> - (for example: apt-get install build-essential) Because this problem might not be PPA or bitcoin-qt-package related, but I misconfiguration in Ubuntu and the package manager itself. Do this if you would like to further continue diagnosing. Yes, I can install build-essential. |

I'm glad to see that you got it working. In the end, you just downloaded the precompiled binaries? If you can't install from source just download the binaries from bitcoin.org. They work out of the box. Just extract the tarball and run.
Ok. I have downloaded it from bitcoin.org and then extracted the tarball. But which application do I need to run the bitcoin-qt file? I am trying with Ubuntu Software Center but I get an error message Open up a terminal in the bin folder and run the following commands chmod +x bitcoin-qt
./bitcoin-qt Every time you want to run bitcoin at, you need to use the second command. Don't close the terminal while the program is running. Thank you very much Abdussamad and knightdk! Now it works  I would like to make a donation to both of you to thank you for your patience and help. Please send me a PM or reply under this post writing your addresses. I am gonna make it as soon as possible. Yes, I downloaded the precompiled binaries from bitcoin.org, extracted the tarball and then opened bitcoin-qt by the terminal. The procedure described here didn't work. |
