apt报错：

Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution)

按照提示来执行：

sudo apt --fix-broken install

又报错:

rocess: Resource temporarily unavailable

解决：

$ sudo fuser /var/cache/debconf/config.dat
/var/cache/debconf/config.dat: 4503

$ ps aux | grep 4503
root 4503 0.0 0.8 10816 9088 ? S 08:39 0:00 /usr/bin/perl -w /usr/share/debconf/frontend /usr/sbin/update-grub

$ sudo kill 4503

After killing the process (4503 in this case) and running update-manager again, the upgrade can be completed successfully.

Errors were encountered while processing:
grub-pc
grub-efi-amd64-signed
gdm3
E: Sub-process /usr/bin/dpkg returned an error code (1)

cd /var/lib/dpkg
sudo mv info info.bak (或用cp)
sudo mkdir info
sudo apt-get update
sudo apt-get -f install  grub-pc gdm3 grub-efi-amd64-signed
sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info.bak
sudo rm -rf /var/lib/dpkg/info
sudo mv /var/lib/dpkg/info.bak /var/lib/dpkg/info
