Linux error messages and solutions
12 Apr 2021 | server linuxThis post is about Linux error messages and solutions I used.
Sub-process /usr/bin/dpkg returned an error code (1)
This error message indicates a problem with the package installer. This can happen in Ubuntu after a failed software installation, or if the installer becomes corrupted.
You can solve the problem by removing unused software packages.
sudo apt autoremove
No space left on device
If you have a separate /boot
partition which is full, you need to clean up manually.
Check which kernel you are using
uname -r
List kernel images
dpkg -l linux-headers-\* linux-image-\* | grep ^ii
Delete kernel images which is not used currently
sudo apt-get remove linux-image-{version not currently used}
