How to get eos-update store logs

Archie1 · May 6, 2025, 6:26am

I typically run Update Native Packages (eos-update) in the Welcome EOS application. What I observed that the output generated from this is not stored in /var/log/pacman or in systemd-log or any other log file.

How can the output/logs of eos-update be stored in a log file? Either in /var/log/pacman or in systemd-log or some other log file?

From what I see here:

github.com/endeavouros-team/eos-bash-shared

eos-update

main

#!/bin/bash

# Package updater for EndeavourOS and Arch.
# Handles db lock file, keyrings, syncing, and optionally AUR with given AUR helper.

echo2()   { echo "$@" >&2 ; }
printf2() { printf "$@" >&2 ; }
WARN()    { echo2 "==> $progname: warning: $1"; }
DIE()     { echo2 "==> $progname: error: $1"; exit 1;  }

SetHelper() {
    for helper in "$@" "$EOS_AUR_HELPER" "$EOS_AUR_HELPER_OTHER" yay paru pacman ; do
        which "${helper%% *}" &>/dev/null && return 0
    done
    WARN "AUR helper not found"
    helper=pacman
}

Cmd() {                           # Show a command, run it, and exit on issues.
    echo2 "==>" "$@"

I dont know why it would not be in your /var/log/pacman.log.
It may sound silly .. but are we sure?

Maybe do the thing and then post the contents of the log?

eos-update uses pacman and optionally yay or paru. The logs go to files specified by them. And that should be /var/log/pacman.log.
Check that the file (and path) is writable.

I checked the /var/log/pacman it does not have the output of the eos-update command. Is there a mechanism to also redirect the output of the command eos-update to a log file? Or to JournalD? Or to another file say /var/log/eosupdate.log or similar?

I havent tried this but maybe tee ?

eos-update | tee ~/eos-update-log.txt

Thanks for your suggestion. But the issue is that this command, i.e. eos-update | tee ~/eos-update-log.txt is not run from the EOS Welcome screen. Is there a way where I can request for it?

@cscs I had a look at the python script for eos-update. Will it be possible for me to suggest to developers and maintainers of the script to add a few additional lines of code into the script functions

echo2()
printf2()
WARN() 
DIE()

such that the output is logged into the stdout/ stderr as well as the logger. If systemd-log, is present there or in another file say /var/log/eos-update.log.

We are always open to suggestions.
Since you already visited our GitHub page, you can request it there or over here.

A little clue: Just look at the top of the page on that script, and you might notice a familiar name as its developer that also appears in this thread.

you mean manuel-192?

Yes, he even uses the same avatar over here. And identifies as dev next to his name.
