Many thx for the hint with these both log files. I have checked them, but i couldn't found other processes installing the mentioned packages. There are only 2 manually invoked apt commands, to manually downgrade and later update wget, but that was a test from my own. I personally think that unattended-upgrades has complained about the kept packages, but lastly installed them.
Im using a 52unattended-upgrades-local file to overwrite the standard file with the following settings:
Unattended-Upgrade::Origins-Pattern {
"origin=Debian,codename=${distro_codename}-updates";
// "origin=Debian,codename=${distro_codename}-proposed-updates";
"origin=Debian,codename=${distro_codename},label=Debian";
"origin=Debian,codename=${distro_codename},label=Debian-Security";
"origin=Debian,codename=${distro_codename}-security,label=Debian-Security";
"origin=Raspbian,codename=${distro_codename},label=Raspbian";
"origin=Raspberry Pi Foundation,codename=${distro_codename},label=Raspberry Pi Foundation";
"site=archive.ntfy.sh";
"site=download.docker.com,a=trixie";
};
Unattended-Upgrade::Package-Blacklist {
};
Unattended-Upgrade::AutoFixInterruptedDpkg "true";
Unattended-Upgrade::MinimalSteps "false";
Unattended-Upgrade::Remove-Unused-Kernel-Packages "true";
Unattended-Upgrade::Remove-New-Unused-Dependencies "true";
Unattended-Upgrade::Remove-Unused-Dependencies "true";
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Automatic-Reboot-WithUsers "true";
Unattended-Upgrade::SyslogEnable "false";
Maybe i have something missconfigured...
13MB is the download size in GP. This is different from fDroid, because you download only a device or architecture specific installer, which is different on fdroid. After installing this extracts to maybe 75mb, which should be identical to fdroid. After first start the app, this can download additional packages, if needed and the wasted space grows. It grows more with the cache and other temporary content. A app can also reserve some space. For some apps, this could be up to 5gb and more.
