Migration to V11: failed because of /boot/ has less than 70MB available

Zblerg I guess you can edit the code directly …

Should be something like

sudo nano /usr/lib/moulinette/yunohost/data_migrations/0021_migrate_to_bullseye.py

Then find this line :

github.com

YunoHost/yunohost/blob/buster/src/yunohost/data_migrations/0021_migrate_to_bullseye.py#L387


      
                  pass
          
          

          
    raise YunohostError("migration_0021_not_buster2")
          
          
# Have > 1 Go free space on /var/ ?
          if free_space_in_directory("/var/") / (1024**3) < 1.0:
              raise YunohostError("migration_0021_not_enough_free_space")
          
          
# Have > 70 MB free space on /var/ ?
          if free_space_in_directory("/boot/") / (1024**2) < 70.0:
              raise YunohostError("/boot/ has less than 70MB available. This will probably trigger a crash during the upgrade because a new kernel needs to be installed. Please look for advice on the forum on how to remove old, unused kernels to free up some space in /boot/.", raw_msg=True)
          
          
# Check system is up to date
          # (but we don't if 'bullseye' is already in the sources.list ...
          # which means maybe a previous upgrade crashed and we're re-running it)
          if os.path.exists("/etc/apt/sources.list") and " bullseye " not in read_file(
              "/etc/apt/sources.list"
          ):
              tools_update(target="system")
              upgradable_system_packages = list(_list_upgradable_apt_packages())

and replace the < 70.0 criteria with whatever … i guess 18 in your case … which sounds uncomfortably low …
