create bootstrap : how to clean leftovers : how to use dumpunreferenced/deleteunreferenced

[ipanmeri]

Hi,
while trying to

mgr-create-bootstrap-repo -c ubuntu-20.04-amd64-uyuni

at the end I get this output:

Skipping inclusion of 'libzmq5' '4.3.2-2ubuntu1' in 'bootstrap|main|amd64', as this version already exists. Deleting files just added to the pool but not used. (to avoid use --keepunusednewfiles next time) Not deleting possibly left over files due to previous errors. (To keep the files in the still existing index files from vanishing) Use dumpunreferenced/deleteunreferenced to show/delete files without references. Warning: database 'bootstrap|main|amd64' was modified but no index file was exported. Changes will only be visible after the next 'export'! Warning: database 'bootstrap|main|i386' was modified but no index file was exported. Changes will only be visible after the next 'export'! Warning: database 'bootstrap|main|armhf' was modified but no index file was exported. Changes will only be visible after the next 'export'! Warning: database 'bootstrap|main|arm64' was modified but no index file was exported. Changes will only be visible after the next 'export'! There have been errors! Error creating bootstrap repo. You have new mail in /var/spool/mail/root

What are the "dumpunreferenced/deleteunreferenced" options and how do I apply them?
Command reference does not explain.

Or, how do I "reset" a bootstrap repo?
Thanks

bootstrap repositories are saved at /srv/www/htdocs/pub/repositories. You can try to find the problematic one and just delete the folder
