started with the CD installer - Jessio-1.0.0
graphical install selected from the boot up menu
no network connection selected - (just needed basickernel/files  to update to the ASCII version)
grub installed  -- rebooted
'
LOGGED IN AS ROOT (which some say not to do - but sudo not avail IIRC)
'    with the 'default session'  not the single panel

/etc/apt/sources.list modified (via nano)
    # the cd source out
    added ONLY deb http://us.mirror.devuan.org/merged ascii main
did an apt-get update (only-not the usual 'upgrade')
'
apt-get install syslog-ng-core syslog-ng  BTW-(this removes rsyslog!!)
[this will do 13 upgrades & 39 new installs files]
**!!!open the details window as there is a list of messages and
**!!! at the prompt :   -I just did a 'q' ;not knowing the source of the messages
told it to automatically restart the services as needed
'
apt-get install synaptic [38 upgraded 29 new installs files]
** keos was having trouble with Synaptic upgrade so I tried it**
!!!open the details window as there is a list of messages and
!!! at the prompt :   -I just did a  'q'  not knowing the source
(you may notice several theme path errors for 'clearlook')
'
fwiw-(Synaptic had scrunched text in menu bar/ missing button outlines)

NOW I added to /etc/apt/sources.list [via nano  I am still user 'root']
    deb http://us.mirror.devuan.org/merged ascii-updates main
    deb http://us.mirror.devuan.org/merged ascii-security main

launched Synaptic (from menu tree)  and clicked on the <Reload> button
opened up the 'details' window - 3 sources listed - loaded 0K 113K 0K
clicked on the <Mark all upgrades> button (214 new 563 upgrade 8 remove)
'
it downloaded some files and appeared to hang (no disk activity)
!!!open the details window as there is a list of messages and
!!! at the prompt :   -I just did a  'q' ' not knowing the source
'
about 20 minutes later it  looked like it hung - BUT it was finished
closing details window resulted in a - POPup a 'sandbox' error message
'

**        uname -a       reports still at 3.16 kernel
attempted to 'Reboot' - [from the menu]       just got a logout/login - did a 'root' user login
NOW I was able to do 'Reboot'   [from the menu]
**  uname -a now reports 4.9.0-3 kernel  !!!!!!
'
launched Synaptic , did a <Reload> button
'details' window shows 0k 113k 0k 0k 6997k 7154k [6 repositories !]
    !! the additional (automagically added) were the 'packages'
       !! and nothing to reported to upgrade
' ASCII
********************  ISSUES (will create bugs if I can pinpoint error)******************
CD wouldn't open from front panel button - needed the filemgr to 'eject'
    Thunar 1.6.11 reported as mounting, then .../media/cdrom was busy!!
'
VLC played ONE time as a normal user - (then tried as  'root')
    wouldn't even open up the application after the one time
NO Sound/audio output from CD / web-browser (pulse-audio nothing showd!)
'
loaded (viaSynaptic) alsa-player-common & depends
this showed a data stream from CD but NO audio/sound
'
bash couldn't find 'nano' (I wanted to copy the 'sandbox' message)
    bash was looking in /usr/bin/nano - it was at /bin/nano [per 'which' command]
'
Synaptic no longer has scrunched text !!!
**********that's it folks - for what its worth
the terminal "apt-get" way to install might be better
- used user 'root' as 'sudo' was not avail

Several times during some of the comments in installing/upgrading to ascii - there is a reference
to /etc/apt/sources.list.d/devuan-ascii.list.
I only find a 'devuan.list' there and its contents are: (after an upgrade)
# autogenerated by devuan-baseconf
# decomment following lines to  enable the developers devuan repository
#deb http://packages.devuan.org/devuan ascii main
#deb-src http://packages.devuan.org/devuan ascii main
'
'
this may explain how 'packages' got imported into Synaptic when I did an ASCII upgrade from
Jessie1.0.0 (installer iso 64bit)
'
I can make a long post - its about 3 pages of stenographers notepad sheets if someone wants it.
Tomorrow, as I am going to work now.
