#190680 — Synaptic problem - physical access to CD drive related

I have 3 machines with differing problems physically accessing the 
CD/DVD drive. To install Debian I routinely use a USB connected drive 
WITHOUT any problem by using the BIOS option to select a boot device.

The SOURCES.LIST(5) man page hints that I should be able us something like
      file:/media/richard/Debian%209.1.0%20i386%201
or
     file:/media/richard/Debian 9.1.0 i386 1

Neither worked. Man page suggest the space characters to be the problem.

I did

When I run Synaptic, it complains about a line in sources.list
    file:/home/richard/Desktop/testdvd stretch main contrib non-free

The error message is
> E: Type 'file:/home/richard/Desktop/testdvd' is not known on line 2 in source list /etc/apt/sources.list

What can I do?

"testcd" is not the same as "testdvd".
(Copy+paste error or the cause of your problem ?)


Have a nice day :)

Now findmnt returns
├─/media/richard/Debian 9.1.0 i386 1  /dev/sr1    iso9660 
ro,nosuid,nodev,relatime,uid=1000,gid=1000,

└─/home/richard/Desktop/testdvd       /dev/sr1    iso9660 
ro,relatime,uid=1000,gid=1000,iocharset=utf

I had tried "umount /media/richard/Debian 9.1.0 i386 1", but umount 
objected to the spaces in the file name.

Synaptic still returns

E: Type 'file:/home/richard/Desktop/testdvd' is not known on line 2 in 
source list /etc/apt/sources.list
E: The list of sources could not be read.
Go to the repository dialog to correct the problem.
E: _cache->open() failed, please report.

Is the problem that the dvd is automounted at boot?
Thank you

"Type" is probably referring to the deb or deb-src entry that is missing.

Have you already used the repository to update your sources? why do you 
want to add the cd/dvd back?

I have found that immediately after install, a commented line 
in sources.list resembling:
#deb cdrom:[debian_installer_version_arch_24-date_etc] stretch main

and if I uncomment this line, and mount the install media at /media/cdrom 
then apt is able to continue installing pkgs from it.

If that won;t work for you, try apt-cdrom

good luck

I've been staring at screen too long.
That at least allows Synaptic to start.

As CD's are not "signed" so to speak I still can't access it.
But I had a closely related problem in April 2014.
I have to reread that thread to become re-educated ;/

Because I don't always have internet and there are physical/mechanical 
problems using the installed drive. The portable drive is convenient and 
sometimes required.

I'll check that out tomorrow.

I don't know about Synaptics, but for the command line you have
to put a file name in quotes whenever it contains spaces (this
is due to the shell separating arguments (by default) at whitespace:
umount sees four arguments then: "/media/richard/Debian", "9.1.0",
"i386" and "1". None of those are a mount point or device (lucky
you ;), thus umount complains).

Use quotation marks to make the directory path a single "word"

  umount "/media/richard/Debian 9.1.0 i386 1"

(It is somewhat astounding that you can mount /dev/sr1 several times.
 On ye olde Jessie kernel i have to use "-o loop" for the further mounts.)

In my /etc/apt/sources.list there is the word "deb" or "deb-src" before
the URL. man 5 source.list says:

   The format for a sources.list entry using the deb and deb-src types is:
       deb [ options ] uri suite [component1] [component2] [...]

This matches the complaint about "Type 'file:...'".

So if you don't have it yet in the file, then try prepending "deb"

  deb file:/home/richard/Desktop/testdvd stretch main contrib non-free


Have a nice day :)

So eliminate the problem. Whitespace characters (& dots & underscores) in
filenames produce more trouble than they avoid. It doesn't happen with downloads
on my machines. e.g., that above would be:

	file:/media/richard/debian09010-i386-1
and next, likely
	file:/media/richard/debian09020-i386-1
and eventually, likely
	file:/media/richard/debian10010-i386-1

cf. my archive of mozilla.org Firefox downloads:
-rw-rw-r-- 1 18999452 Jan  3  2013 firefox-10012esr64.tar.bz2
-rw-rw-r-- 1 23590858 Nov 13  2013 firefox-17011esr64.tar.bz2
-rw-rw-r-- 1 38882500 Sep 24  2014 firefox-3111esr64.tar.bz2

-rw-rw-r-- 1 57692607 Dec 27 10:47 firefox-5253esr64.tar.bz2

ls -gG produces same result as ls -gGrt :-) With any luck the Rapture will occur
before Firefox versions reach triple digits. ;-)

Dots and underscores in filenames do little more than make filenames longer and
harder to touch type, but commonly also cause alphabetical sorts to undesirably
differ from age/version sorts[1]. Here, Shift-F6 in OFM fixes any created by
other than myself.
