As part of getting the ready for future developments Elive has already set up repositories to allow a switch to Debian 11 Bullseye.
All existing Elive installations as well as the live version still use Debian 10 Buster as it's base and will continue to do so until the shift is considered stable and fool proof. Enabling people to decide for them selves whether they want try out and test this imminent shift, here's a small Howto explaining the steps I took to get there.
In chronological order:
Make sure to fully upgrade your existing system using the 'apug' command in the terminal.
Change the entries in '/etc/apt/sources.list.d/debian.list' to reflect the new Bullseye base. It should have the following entries:
xxxxxxxxxxdeb http://deb.debian.org/debian bullseye main contrib non-freedeb http://deb.debian.org/debian-security bullseye-security main contrib non-freedeb http://deb.debian.org/debian bullseye-backports main contrib non-free
The Elive repositories require changing too. They're in '/etc/apt/sources.list.d/aaa-elive-list' and should contain
`deb http://repo.bullseye.elive.elivecd.org/ bullseye main elive efl games ports fixes drivers multimedia non-free
as well as '/etc/apt/sources.list.d/ggg-marillat.list' to contain
deb http://www.deb-multimedia.org bullseye main non-free
or if you want to be really lazy you could use the following command and make all the needed changes in one go by using the following (all in one line) command:
sudo sed -i -e 's/buster/bullseye/g; s/bullseye\/updates/bullseye-security/g' /etc/apt/sources.list.d/*.list
After checking that the sources list files are changed correctly you can run the 'apug' command again.
And get yourself a beverage or something because there will be quite a lot of packages to download and install and .... there will be a few (2-3) questions asked, which in general can be answered with the set default (y or save) as well.
Upgrade your kernel manually as the upgrader (apug) will not do that for you. First check out which kernel you currently have with:
'uname -a'
where essentially the extension is of importance, like: "bpo.2-amd64". (the number behind the bpo may differ)
You can then search for the most recent available kernel for Buster with the command:
'apse linux-image | grep bpo'
and subsequently chose the latest version (currently 5.14.0-0) and conform to the found extension and install that with
'api linux-image-5.14.0-0.bpo2-amd64 linux-headers-5.14.0-0.bpo2-amd64'
And reboot your system into your new kernel.
and even more known issues for Debian in general: https://www.debian.org/releases/bullseye/amd64/release-notes/ch-information
The sound card may not work and might require a work around with:
killall -9 pulseaudio
rm -f /home/*/.config/pulse/cookie /home/*/.pulse/*
pulseaudio --start'
On my personal machine the audio-volume up/down keys didn't work for E16 and required a change in the keybindings but it didn't seem to happen to everyone.
Anyway, if it does happen, the following line will see to that:
sed -i -e "s/5\ up/+5%/g; s/5\ down/-5%/g" ~/.e16/bindings.cfg
In Bullseye python2 has been removed and superseded by python3. To change all bindings to reflect python3 you need to install th 'python-is-python3' package:
'api python-is-python3'
If you like playing retro games, specifically 'syusokoban' you'll need to re-install it as the previous one was an i386 version. Thus:
apr --purge syasokoban
api syasokoban
All the above can be shortened down to one go:
killall -9 pulseaudio
rm -f /home/*/.config/pulse/cookie /home/*/.pulse/*
#uncomment the following line for audio up/down keys if needed:
#sed -i -e "s/5\ up/+5%/g; s/5\ down/-5%/g" ~/.e16/bindings.cfg
apr --purge syasokoban
api syasokoban python-is-python3
apug
#reboot your computer now
And have a look round your shiny new Bullseye based Elive system and have fun.
