RFC: keep an elder nightly around

please keep a least one elder nightly around for download when a newer nightly is build.

I'm running nightly "in production" on a daily base with daily updates.

it has some risks [1] - I know -

but doing so, has - for my view - the advantage to get the bugs they're (maybe) still in getting reported and fixed.

YMMV

but there should be a easy backup/fallback solution if the last nightly doesn't play well.

I know I could

- run a additional LE e.g. LE Release on a usb stick

- download nightly twice and keep the elder one

- ...

Regression: libhdhomerun.so: cannot open shared object file

with today nightly (nightly-20211225-9841784 (Generic.x86_64)) TvHeadend (v10.80.2.102) stopped working

in it's service.log:

/storage/.kodi/addons/service.tvheadend43/bin/tvheadend: error while loading shared libraries: libhdhomerun.so: cannot open shared object file: No such file or directory



backup restore doesn't work/fixed it here

anywhere to get the yesterday nightly ?

until today I was the opinion that a LE backup saves me against all risks.

I've learned: no, not all !

thanks chewitt

I wonder how do you do this:

do you do the download on the LE box only (no 2cd box involved) ?

how do you get the correct download link for the new nightly ?

does a web-browser sorta Lynx as an addon or so exists (currently can't find one) ?

with system tools installed:

it would be sufficing if an

wget https://test.libreelec.tv/LibreELEC-Gene…4-11.0-nightly-*.tar

would work ... (as long as only one nightly is in that directory)

alas not

+++ EDIT +++

wrote a small script (maybe needs some improvements...?!)

I guess it's mostly self declaring

- "&&" := short hand "if-then"

- fetch the new nightly *name* from the server

- check if the server's nightly is already running on the box

if not:

- download the last nightly from the server into ~/.update/

- backup a copy to ~/backup/

be aware: no warranty by me !!!

be aware: the script fills up ~/backup

#!/bin/bash

NIGHTLY="LibreELEC-Generic.x86_64-11.0-nightly-";
SERVER_URL="https://test.libreelec.tv";

# clean in any case ~/.update/
rm -rf ~/.update/*;

# operate in /tmp and clean up before
cd /tmp/ && rm -rf releases.json*;

wget ${SERVER_URL}/releases.json;

[ -e releases.json ] && NEW_NIGHTLY=$(grep -i ${NIGHTLY} releases.json | grep tar | cut -d: -f2| sed -e 's/"//g' -e 's/ //g' -e 's/,//g');

if [ ! -z "${NEW_NIGHTLY}" ]; then

   # get currently running nightly version   
   CURRENT_NIGHTLY=$(cat /etc/issue |grep nightly|cut -d: -f2|cut -d "(" -f1|sed -e 's/ //g');

   # and compare with the one on the server
   RC=$(echo ${NEW_NIGHTLY} | grep ${CURRENT_NIGHTLY});

   [ ! -z "${RC}" ] && echo -e "\n lastest nightly already running \n" && exit 13; 
   
   echo -e "\n fetching ${NEW_NIGHTLY} \n\t wait ...\n";
   
   # clean ~/.update, download new nightly to ~/.update/ and save a copy to ~/backup/
   cd ~/.update/ && rm -rf *;

   wget -nc ${SERVER_URL}/${NEW_NIGHTLY};

   cp *.tar ~/backup/;
   
   echo -e "\n\n reboot to install the new nightly, e.g. \n\n\t "sync && sync && systemctl reboot" \n";

else
   echo -e "\n No new nightly \n";
fi;


exit 0;

yup, quiet clear, did it the same, but the main background of my question was "how to do it *without* a second box.

anyway the above script works for me.

if you want, you could use the script after adjustments, as you're anyhow ssh intoyour LE.

if you got questions, just ask !

to prepare the script for your rock54 box adjustments are needed:

line 3 to:

NIGHTLY="rock64";

and

line 14 to:

[ -e releases.json ] && NEW_NIGHTLY=$(grep -i ${NIGHTLY} releases.json | grep .gz | cut -d: -f2| sed -e 's/"//g' -e 's/ //g' -e 's/,//g');

alas I'm able to test it here only partly, means: a download starts

but I can't test line 22, where the last rock64 nightly is already installed and I therefore want to prevent the unnecessary download.

I would need a rock64 box (or at least the out of "cat /etc/issue"), but I don't own one !

questions to the developer/maintainer:

compared to generic, why do only *.gz exists for of "LibreELEC-RK3399.arm-11.0-nightly"
