So, I type "apt install mysql-server-8.0" and it comes back with:

I've tried uninstalling, reinstalling, installing. Nothing works. I moved the related .deb files to /tmp from /var/cache/apt/archives/ and still I cannot get this outta my system. mysql 5.7 appears to still be on this machine and attempting to remove that results in the same errors. I'm at my witts end. Google is no help (followed many a directions, including the one here: https://itsfoss.com/dpkg-returned-an-error-code-1/ to no avail).

So I did: dpkg --configure -a and it spits back:

dpkg: dependency problems prevent configuration of mysql-server-8.0:
 mysql-server-8.0 depends on mysql-server-core-8.0 (= 8.0.20-0ubuntu0.20.04.1); however:

Ubuntu 20.04 LTS

apt mysql reinstall 20.04

I'm a very long time ubuntu user (over a decade) but have not been here as I've had no issues with Ubuntu. With the arrival of 20.04 LTS I decided to encrypt my data (or system if needed). I'm looking for the following:

  • Method to reinstall ubuntu with LUKS encryption on a previous LUKS encrypted ubuntu install on a dual boot system with Win10.
  • Keep all my personal files (ie /home folder) intact, with or without a separate partition. I do not wish to move everything out, reinstall and then move stuff back in.
  • Simple GUI based approach through the standard installer. I know how to use the command line but I'd rather not, especially for something as sensitive as encryption.

What I'm looking for is basically the same as this document: (https://help.ubuntu.com/community/UbuntuReinstallation) except that I need it on an LUKS encrypted system/partition. I tried doing this on a spare system with 20.04, and I could not find a way of telling the installer the passphrase to the encrypted system. The end result was a reinstall that wouldn't boot or the encrypted partition gets wiped out. I also tried to run installer with and without pre-unlocking the encrypted partition but to no avail'.

I am able to do all of the above with Fedora,OpenSUSE,Manjaro, (although they only do this when /home is on separate partition, which is fine for me) so I'm not sure what I'm doing wrong in Ubuntu.

Thanks!

I was experiencing problems with Ubuntu Desktop like missing and broken system packages, missing Unity package and other problems. So I decided that the best solution (without touching Windows files) is just to reinstall Ubuntu.

I looked everywhere and found the way but got confused as some say that I supposed to choose "Erase Ubuntu and reinstall", others say that I supposed to choose "Something else" and just select it manually while installation. I thought the first option would be better and just safer as I don’t want any of Windows files to be touched but it says that it has a bug that erases all other partitions...

  • Current Ubuntu version: 17.04 desktop 32bit

  • will be replaced with 16.04.0 desktop 32bit (as 32bit 17.04 version is no longer available)

What’s the safer option to choose? And if the second one is, how to make sure it’s Ubuntu partition?

dual-boot reinstall
