gcc-8 package

gcc-8 broken packges bionic arm64 after update

Asked by alex-mobigo

I had gcc-8 , cpp-8 , g++-8 installed and was running fine on my ubuntu 18.04 LTS along with gcc-7 (7.3.0).
After a 'sudo apt-get update && sudo apt-get dist-upgrade' gcc-8 and the sibling tools had been removed.

I thought well i can just re-install them:
sudo apt-get install cpp-8 g++-8 gcc-8 gdc gdc-8 libstdc++-8-dev

and then i have this:

sudo apt-get install cpp-8 g++-8 gcc-8 gdc gdc-8 libstdc++-8-dev

So seems gcc-8-base is outdated or missed in the update or 7.4.0 can't be run along with 8.3.0.

The question is/are:

a) How can i fix this and get back my gcc-8 (without breaking my distro)
b) How this could have happened?

Hmm, I can't remember why i enabled the proposed repository (perhaps to get gcc-8) , i have been running (dist-upgrade) like so for about a year without issues until yesterday.

Yes, i am not an average user.

I would like to understand what packages prevent gcc-8 to be installed and fix it.

For gcc-8-base and libgcc-8-dev the package management suggests version 8.3.0-6ubuntu1~18.04.1 from bionic-proposed/main, but for all other packages it is only version 8.3.0-6ubuntu1~18.04 from bionic-updates/universe

Maybe you have enabled bionic-proposed only for main, but not for universe?

What is the output of the commands

uname -a
lsb_release -crid
cat -n /etc/apt/sources.list

TBH, i can't remember to have enabled bionic-proposed at any time. in the /etc/apt/sources.list. I usually just uncomment the line. Is it possible to enable bionic-proposed, do an update/dist-upgrade and then disable it, and run for a year?

It seems that the setting for bionic-proposed is in a different configuration file.

What is the output of

find /etc/apt/sources.list.d -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;

That's it. You have enabled bionic-propsed only for main and restricted, but not for universe and multiverse.
You have to be aware that some of the gcc-related packages are in main, and some are in universe.

Suggestions for a solution:

Disable bionic-proposed for all components and downgrade gcc-8-base and libgcc-8-dev to the version in bionic-updates (8.3.0-6ubuntu1~18.04); eventually the same for other packages that currently were loaded form -proposed

or

Enable bionic-proposed also for universe (and multiverse), run apt update and try installing gcc-8 again, and this should take the version from -proposed.

Maybe this explains what happens: https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/1803338

So, what about enabling bionic-proposed for universe, install the missing gcc-8 files and disable bionic proposed? Would this woks?

Revision history for this message
Manfred Hampl (m-hampl) said : 		#12

That bug seems to be an explanation for your problem.

And yes, enabling bionic-proposed/universe, installing gcc-8 and then disabling all bionic-proposed repositories, should work.
The only remark: you must be aware of the situation; and in case that a similar problem re-occurs (maybe with other packages), you know what the cause could be, and what you can do.
