Ubuntu: 18.04

When I tried to do sudo apt-get upgrade it gives me this error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
The following packages were automatically installed and are no longer required:
  libpython3.7-minimal libpython3.7-stdlib
Use 'sudo apt autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

Errors were encountered while processing:

But suggested commend sudo apt autoremove also shows error:

The following packages will be REMOVED

So it looks like there is some problem with py3compile which is not found. I try sudo apt-get -f install which ends with:

Reading state information... Done
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

The same kind of py3compile: not found error shows when i try sudo apt-get install --reinstall python3-minimal

I'm new with ubuntu so I will be glad for some help with that.

  • It may be worth trying to remove packages one by one, for example like this: sudo apt remove libpython3.7-minimal – Elias Apr 7 at 11:15

dpkg error: pycompile: not found - Stack Overflow

This answer helped me, hope it resolves someones problem.

Reconfigure all unpacked, but unconfigured packages by:

sudo dpkg --configure -a

If above won't help, try reinstalling python3-minimal package by:

sudo apt install -f --reinstall python3-minimal

Alternatively run:

apt-get download python3-minimal
sudo dpkg -i *python3*.deb
sudo apt install -f

Or download the .pkg file from kernel.org and install from the file by:

sudo dpkg -i python3-minimal_*.deb
