$ apt-cache policy python3.8
python3.8:
  Installed: (none)
  Candidate: 3.8.2-1
  Version table:
     3.8.2-1 50
         50 http://pkgmaster.devuan.org/merged chimaera/main amd64 Packages
         50 http://pkgmaster.devuan.org/merged ceres/main amd64 Packages

chimaera won't be any more stable than ceres until debian bullseye goes into freeze. Some of the packages we fork are being made ready for ceres now, and they will migrate into chimaera pretty quickly when they're done.

Check all the usual suspects for desktop power control (shutdown/reboot/hibernate). (policykit, libpam-elogind, upower...)

python3.8 is also in chimaera (our next testing when beowulf goes stable).

ceres=sid=unstable

Thanks for all your help.

too bad i did not notice that= chimaera,

as i upgraded toCeres (Planet1) and my ability to rest*hibernate* and the like was gone.

also, here https://pkginfo.devuan.org/ the package search for

testing

is greyed out, so it is not seeable if

has python3.8?

Thanks again, hope to find a stabler solution with Linux.

ceres=sid=unstable

are not yet available,

so i resorted to include

and could install python3.8 from there (next to upgrade some other packages).
after i changed repository from

to

the packages from ceres would become installable (to solve the error above, again

sudo hwclock --hctosys 

had to be applied > so the system has problems with timezone fuss in the european-union > understandably)

hope this will not lead to further complications

Not sure why though

And off-topic for this thread but:

If you're dual-booting with Windows then you should force Windows to use UTC rather than make GNU/Linux use a stupid time standard:
https://wiki.archlinux.org/index.php/Sy … in_Windows

And make sure that ntp is installed & enabled to keep your clock correct.

Once that's done and Devuan is using the correct time run

sudo hwclock --systohc

but the similar error as above would occur upon including the repository

sudo apt-get -o Acquire::Check-Valid-Until=false update
Get:1 http://deb.devuan.org//merged ceres InRelease [25.6 kB]

when i then comment out

the error would remain.

after

https://askubuntu.com/questions/1096930 … -yet-valid

applying

sudo hwclock --hctosys 

sudo apt update

would return normal, but only unless i don't include beowulf-backports?

i just recently upgraded to Devuan Beowulf.

For a program "SVP - Smooth Video Project")

i would like to install the newer version, but it requires Python3.8

can i yet install this on Devuan?

it seems it is available on Debian Testing

https://packages.debian.org/search?keywords=python3.8

Thank you!
