  • apt-get update executes without a single error

  • Something happened to firefox-esr on this system.

  • sudo apt install -y python3-venv

    Depends: python3-distutils (>= 3.7.2-1~) but it is not going to be installed
    
  1. debian requires firefox-esr or chromium to be installed. This causing problems with venv install.
  2. Fix broken firefox-esr:
 :~# apt --fix-broken install
The following packages will be upgraded:
firefox-esr
1 upgraded, 0 newly installed, 0 to remove and 7 not upgraded.
66 not fully installed or removed.
Need to get 56.0 MB of archives.
After this operation, 19.5 kB of additional disk space will be used.
E: You don't have enough free space in /var/cache/apt/archives/.
  • Try apt cleaning options
sudo apt-get autoclean
sudo apt-get autoremove 
sudo apt-get clean
  • Try re-route the location where .debs are stored:

Link: re-route the location where .debs are stored

mkdir /media/apt-mount/
mount /dev/sdb4 /media/root/cache-apt/
sudo mv -i /var/cache/apt /media/apt-mount/
ln -s /media/apt-mount/apt/ /var/cache/apt

apt-get update still executes without any error msg

apt --fix-broken install still causes

E: You don't have enough free space in /var/cache/apt/archives/.

How to fix not enough free space error ?

You could try to purge removed packages with lingering data with dpkg like

sudo dpkg -P $(dpkg -l | awk '$1=="rc"{print $2}' | xargs)

This also cleans out old kernels properly.

Explanation for the awk command is that it find lines where the first column is rc and prints the second column.

  • produced error=> dpkg: error: --purge needs at least one package name argument.....i am suspecting an issue how debian peristence handles dpkg...tmpfs or something. – t09 Jan 13 at 0:09

You can always manually clean out the contents of /var/cache/apt/archives. It's just old downloaded package files. If you don't mind having to download them again if you reinstall, you can remove them all:

find /var/cache/apt/archives -name \*.deb -delete

To keep the directory from filling up again, you can disable storing downloaded package files by setting

Dir::Cache::pkgcache ''

in apt.conf. See man apt.conf. Or, create a nightly cron job to clean out the directory as above.
