Problem
When i launch migration to 11, here my log : https://paste.yunohost.org/raw/dogocoxase
Apprently libgcc is causing the problem
any thoughts ?
Hmyeah we saw a few people encountering that issue already, but we don’t have a straightforward way to address it.
libc6-dev : Breaks: libgcc-8-dev
This is most probably related to an app requiring build-essential which is only needed to build the app, but not to run the app itself.
There may be multiple way to address this
But first let’s identify the problematic app by running :
dpkg -s $(dpkg --list | grep ynh-deps | awk '{print $2}') | grep 'Package:\|Depends:' | grep 'build\|gcc\|g++' -B1
Edit:
and apt policy libgcc-8-dev
and apt policy gcc-8-base
Sane here.
I have:
The package is being used by NetData. I will erase it and try to migrate.
Thanks
ps. nope, migration fails. Same issue. I uninstalled NetData, but there is still netdata-ynh-deps that is causing the issue. What next?
apt remove netdata-ynh-deps
apt autoremove
It’s seems that it’s Vaultwarden…
Indeed

Please folks …
I took time to prepare 3 commands to run and you’re not even providing the exact output of one command (cf also @lapor 's post)
To be able to fully understand what going on, we need the exact and full output of each command …
This is pretty brutal, I was going to advise that many people on the internet report successfully solving the issue by just running apt install gcc-8-base … But I was hoping to look at the apt policy first to get the full picture and understand why this fixes the issue … Also it’s not clear to me if the issue is related to build-essential or rather gcc/g++ dependencies, which I was hoping to get clues from the actual output of dpkg -s ...
Sorry i was just reacting to @lapor who has already removed netdata apps… But i let you advice them in a better way.
Thanks for the replies. I missed the other commands, so I’ll reinstall NetData and check with all of the command and report back. I was in a hurry before 
So, i have to uninstall vaultwarden, then try again ?
We were able to make some progress with @Thatoo on the chat who encountered the same issue
I crafted a small hack that removes the dependency to build-essential from the $app-ynh-deps :
sudo cp /var/lib/dpkg/status /root/dpkg_status.bkp
sudo perl -i~ -0777 -pe 's/(Package: .*-ynh-deps\n(.+:.+\n)+Depends:.*)(build-essential, ?)(.*)/$1$4/g' /var/lib/dpkg/status
After which we still had to :
# (NB: READ CARREFULY what the next command says
# and make sure it doesnt remove half of the system ...)
sudo apt remove build-essential gcc-8 libgcc-8-dev
The command should display something like :
The following additional packages will be installed:
binutils binutils-arm-linux-gnueabihf binutils-common cpp cpp-10 gcc gcc-10 gcc-10-base libasan6
libatomic1 libbinutils libcc1-0 libctf-nobfd0 libctf0 libgcc-10-dev libgcc-s1 libgomp1 libisl23
libubsan1
Suggested packages:
binutils-doc cpp-doc gcc-10-locales gcc-multilib flex bison gcc-doc gcc-10-doc
Recommended packages:
libc6-dev
The following packages will be REMOVED:
gcc-8 libgcc-8-dev
The following NEW packages will be installed:
cpp-10 gcc-10 gcc-10-base libasan6 libctf-nobfd0 libctf0 libgcc-10-dev libgcc-s1 libisl23
The following packages will be upgraded:
binutils binutils-arm-linux-gnueabihf binutils-common cpp gcc libatomic1 libbinutils libcc1-0
libgomp1 libubsan1
NB : if this displays MUCH MORE packages than this, this is not good. Otherwise, you may safely proceed
After which, re-running the migration should be ok
We can’t say shit because you are not sharing the output of the command that were requested, and we have no clue as to why you think vaultwarden is the culprit
I finally managed to get some spare time to check it out. I reinstalled NetData and run the commands. I get this:

I hope it helps somehow.
Thanks and cheers
I am also running into this issue (libgcc-8-dev) when attempting to migrate a 4.4.x server (RasPi) to 11.x:
https://paste.yunohost.org/raw/remofuguri
Don’t seem to be getting anything concrete when running Aleks’ commands:
https://paste.yunohost.org/raw/izebigazuw
Here are the apps that I’m running, domain_path removed for OPSEC sake:
For anyone encountering the issue, feel free to try the commands described just a few messages before … Migration to 11 won't start - #12 by Aleks
Hey there,
running in an issue as well. Already tried Aleks approach Migration to 11 won't start - #12 by Aleks, but didn’t
work.
Here is the log file of the migration tool: https://paste.yunohost.org/raw/muziluvuyi
Any help is appreciated. If further logs are necessary please let me know.
Thanks a lot, virse
Dear Aleks,
Sorry about what you thought was irrespectful, i didn’t mean it, i was on my cellphone, no copy paste possible, and i was writing what i was reading. So now, i’am on computer, i willl.
So for : dpkg -s $(dpkg --list | grep ynh-deps | awk ‘{print $2}’) | grep ‘Package:|Depends:’ | grep ‘build|gcc|g++’ -B1
I’ve got

Tell me if i can give you more,

After this command:
sudo apt remove build-essential gcc-8 libgcc-8-dev
I get this:
Reading package lists… Done

Reading state information… Done
Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
@lapor : hmm okay, let’s maybe try this instead (battling with apt is always a pain)
sudo apt remove build-essential
sudo apt autoremove
sudo apt remove gcc-8 libgcc-8-dev
