repositories failed to initialize alpm library

[D3SOX]

Version: 2.9.5.1

I just ran in to this issue where it would not refresh anymore

repositories: error: failed to initialize alpm library:
(root: /, dbpath: /tmp/checkup-db-)
could not find or read directory
aur: error: failed to initialize alpm library:
(root: /, dbpath: /tmp/checkup-db-)
could not find or read directory

I diagnosed it with AI and this is what fixed it

#!/usr/bin/env bash
PLASMOID="$HOME/.local/share/plasma/plasmoids/com.github.exequtic.apdatifier"

sed -i \
  's/checkup-db-${UID}/checkup-db-$(id -u)/' \
  "$PLASMOID/contents/tools/sh/utils"

sed -i \
  's/checkup-db-${UID}/checkup-db-$(id -u)/' \
  "$PLASMOID/contents/tools/tools.js"

systemctl --user restart plasma-plasmashell

Looking at the code I don't know why $UID is not set for me here

Probably irrelevant but checkupdates works just fine

I used the same path as checkupdates to maintain compatibility: "${TMPDIR:-/tmp}/checkup-db-${UID}".

However, this path is also used when executing the command in tools.js in the QML data engine:

apdatifier/package/contents/tools/tools.js

Line 12 in ef42305

const dbPath = "${TMPDIR:-/tmp}/checkup-db-${UID}"

apdatifier/package/contents/tools/tools.js

Line 273 in ef42305

execute(`pacman -Qu --dbpath "${dbPath}" 2>&1`, (cmd, out, err, code) => {

Most likely, the UID variable is empty there for you, whereas for me it’s correctly set to 1000.

Does it work if you replace it with $(id -u)?

Does it work if you replace it with $(id -u)?

Yes this is what I was saying with "this is what fixed it"

Btw as expected updating to 2.9.5.2 broke it again

I'm still unsure why this suddenly happens to me? Did this part of the code change recently?

[exequtic]

It is now possible to specify a custom path for temporary pacman database in the settings. For the default path, $UID has been replaced with id -u.

Did this part of the code change recently?

Yes, there were changes. The widget now synchronizes the database on its own and no longer uses checkupdates for this.

Great! Off-topic: Which Plasma or Kvantum style are you using here? Looks clean

Which Plasma or Kvantum style are you using here?

I use only the Darkly application style
