Permissions and sound

Post by greenstar » Sun Dec 10, 2017 11:06 am

Hi, am sure this is a REALLY stupid question, and I know both have been discussed before. I would, please, like to be directed to the best place, preferably for someone with minimal knowledge of the command line.
Two problems.
Problem 1. I can read but cannot write to my secondary hard drive, installed on the computer, and also not to an external hard drive. I can read and write to usb sticks, but that's not enough for proper back ups.
I am told 'the destination is read only' and find when I change permissions the window immediately reverts to read only.
Problem 2. No sound. The was sound and it worked perfectly just after install. Then for no reason and without explanation I found it didn't.

I have to say that asking a friend who also used Linux I found he also had suffered from both issues with different installs, the permission thing seems to be a 'frequently recurring problem' across various versions and editions, and appears several times on different forums .... His response to the permissions issue was to set up a server on a second computer, it was a b£$"%rd to sort out otherwise but he has been a programmer and engineer for 40 years!

thanks,
Tony

With the un-writable device(s) connected, try these, and post the results inside "code" tags:

Code: Select all

sudo blkid
and

Code: Select all

df
and

Code: Select all

ls -al /where/you/cant/write
Problem 2. No sound. The was sound and it worked perfectly just after install. Then for no reason and without explanation I found it didn't.
First make sure nothing is muted - run

Code: Select all

while playing something you should hear. Check "Output" devices.

Fixing permissions should be easy for anyone familiar with linux or unix. Sound really is a common issue with no standard answer - I make it easier by not using pulseaudio, which IMHO, is the main cause of audio problems. (But don't uninstall it unless you know what you're doing).
Please edit your original post title to include [SOLVED] if/when it is solved!

Hi, sorry this is taking me so long. I have to put aside time to do this and I have a fair bit to do at present, so this will be intermittent.
Flemur, thanks, if I understand correctly you are asking me to enter the commands you suggest in the terminal, with the drives I cannot write to connected, these being a secondary hard drive in the pc, an external 1Tb hard drive, and also a 20Gb usb drive that has suddenly become read only:

Code: Select all

Permissions issue still needs fixing - HELP! I am hoping somebody sees this as the post seems totally buried and no way to bump!

Replace "/where/you/cant/write" with the actual path/directory WHERE YOU CAN'T WRITE because of the permission issue.

Edit: that would be something like:

Code: Select all

ls -al "/media/tony/Tiger  BU 20 Gb"
IF that is where your problem is. You'll need the quotes because of the delimiters (spaces) in the path and partition label.

"root" owns the files, and yup, the permissions exclude you.

I am extremely nervous and concerned not to lose any data on that 1Tb disc, as these are the files I backed up from my mac, cannot be replaced, archived files.
Please reassure me that running commands such as mount unmount etc will not affect file content?
Sorry, but as this is over my head and I do not properly understand I am somewhat nervous at losing data. Such as my entire archived photo collection, etc.

Great. Now I find most of my usb sticks are regarded as read only. This was not an issue with ubuntu (but that had the permissions glitch)
And I am sorry, but the information on the links are incomprehensible to me.
Starting to look like the os is not for me ....
Am I asking stupid questions? It does seem to be the case.
