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
root@stretch17oct2017:/home/richard# findmnt
TARGET SOURCE FSTYPE OPTIONS
/ /dev/sda9 ext4 rw,relatime,errors=rem
.
.
.> └─/media/richard/Debian 9.1.0 i386 1 /dev/sr1 iso9660
ro,nosuid,nodev,relati
root@stretch17oct2017:/home/richard# mount /dev/sr1 /home/richard/Desktop/testcd
mount: /dev/sr1 is write-protected, mounting read-only
root@stretch17oct2017:/home/richard#
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
E: The list of sources could not be read.
Go to the repository dialog to correct the problem.
E: _cache->open() failed, please report.
What can I do?
TIA
