No updates since @ 3 months

Installed Netrunner-desktop-1901-amd64 on 22nd Jan 2019.
Till 10th Apr 2019, there was not a single update offered.
Hence referred thread

As I want to remain on buster,made following changes through Synaptic>Settings>Repositories

  1. Deselected testing main contrib non-free
  2. New added and kept enabled buster contrib non-free main
    and reloaded repos.
    I have a ‘sources.list’ file at ‘/etc/apt/’ which displays
    _# deb testing non-free contrib main _
    deb buster main non-free contrib

Now Synaptic shows 1268 packages upgrdable and mintupdate shows 522 recommended updates available.
Kindly advise, can I proceed with mintupdate?
(I have taken backup of netrunner1901 partition with clonezilla).

Is there some reason to keep the configuration so, if not, I request the team to keep a sticky regarding reconfiguration of the reps to get updates as it is not being done by the updater automatically.

Thanking you in anticipation.

Yes you can proceed.

We have a article on how to enable testing updates already

Hi Jag59,

does this work for you?

Yes, it worked with changes made in repos as mentioned in my 1st post…
Sorry for the delay in replying, I didn’t notice your post earlier.
On 11th Apr 2015,Update Manager (mintupdate) showed 525 recommended packages to update. Then 4 to remove and additional 146 to install. Proceeded with it. Got downloaded @ 1+ GiB packages, took further 50 min. to get installed. During installation, after preparing packages, it asked

You will need a way to toggle the keyboard between the national layout and the 
standard Latin layout.

Right Alt or Caps Lock keys are often chosen for ergonomic reasons (in the 
latter case, use the combination Shift+Caps Lock for normal Caps toggle). 
Alt+Shift is also a popular combination; it will however lose its usual behavior
in Emacs and other programs that use it for specific needs.

Not all listed keys are present on all keyboards.

  1. Caps Lock          7. Alt+Shift                 13. Left Control
  2. Right Alt (AltGr)  8. Control+Shift             14. Left Shift
  3. Right Control      9. Control+Alt               15. Left Logo key
  4. Right Shift        10. Alt+Caps Lock            16. Scroll Lock key
  5. Right Logo key     11. Left Control+Left Shift  17. No toggling
  6. Menu key           12. Left Alt

Answered 10 here.

There are services installed on your system which need to be restarted when

certain libraries, such as libpam, libc, and libssl, are upgraded. Since these

restarts may cause interruptions of service for the system, you will normally be

prompted on each upgrade for the list of services you wish to restart. You can

choose this option to avoid being prompted; instead, all necessary restarts will

be done for you automatically so you can avoid being asked questions on each

library upgrade.

Restart services during package upgrades without asking? [yes/no] yes

Is answering ‘yes’ to pt. 2 above OK?
It seems, as per pt. 3 above, I can remove ‘cryptsetup-initramfs’ to avoid this warning, should I remove it?
Resuming from hibernation works properly, no problem there.

Thanks Netrunner team.
Thanks starbuck for the ‘enable continous updates’’ link. I had searched it earlier but was unable to find.
