Debugging errors during the install via the ISO
- Launch the install in a virtualbox
- Actual logs appear in tty 4, you can switch to it by pressing Alt+F4
- You can manually launch commands from another tty (e.g. the 2nd) but the output will appear in tty4...
- To actually enter the real system (chroot ?) you'll need to run
- see also .. next section
Debugging errors in a chroot
The .deb install can crash for stupid reasons during ISO install because it's in fact ran inside a chroot.
To easily reproduce and investigate the issue, it's easier to manually create a chroot (for example inside an ynh-dev LXC):
apt install cdebootstrap -y cd /root/ mkdir mychroot cdebootstrap --arch=amd64 buster ./mychroot/ http://deb.debian.org/debian/ mount -t proc none ./mychroot/proc mount -o bind /dev ./mychroot/dev chroot ./mychroot/ bash
systemctlshould display "Running in chroot, ignoring request." (compared to some error about PID1 if you didnt mount proc and dev)
- Then run the install, for example using the install script
curl https://install.yunohost.org | bash(you'll need to install curl first)
- The install will crash (otherwise you wouldn't be reading this ? ;))
- You can
nano /var/lib/dpkg/info/yunohost.postinstand edit that script ... for example adding
-xto the shebang (= very first line) to have the debug detail when the script will run. Possibly you may want to also tweak the init regen conf hook call (for example also adding
-xto the bash call there)
- Re-run the install with
apt install yunohost
