migration to new server fails on restoring mail… EACCES: permission denied

[chymian]

@nebulon

this i kinda urgent!!

I'm in the process of moving my complete cloudron 4.2.7 from an OVH-VM to my own dedi.
restoring the backup fails with:

EACCES: permission denied, open '/home/yellowtent/boxdata/mail/vmail/USERNAME@xxx.xxx/mail/dovecot-uidvalidity.5cbf06e5'

• it has already restored 2,5G of mails from other users w/o errors.
• filesystem looks ok.
• no systemlog errors.

The directory in question looks like:

drwx------ 2 yellowtent yellowtent 4,0K Apr 23  2019 cur
-rw------- 1 yellowtent yellowtent  768 Apr 23  2019 dovecot.index.cache
-rw------- 1 yellowtent yellowtent 1,7K Apr 23  2019 dovecot.index.log
-rw------- 1 yellowtent yellowtent  106 Apr 23  2019 dovecot-uidlist
-rw------- 1 yellowtent yellowtent    8 Apr 23  2019 dovecot-uidvalidity
-r--r--r-- 1 yellowtent yellowtent    0 Apr 23  2019 dovecot-uidvalidity.5cbf06e5
drwx------ 2 yellowtent yellowtent 4,0K Apr 23  2019 new
drwx------ 2 yellowtent yellowtent 4,0K Apr 23  2019 tmp

how to proceed?
can I just restart the restore?
can I manually restore single apps, when the box-restore failed, or does that mix up the rest? I'm thinking of mail-settings, DNS, etc.

Please try again on a fresh Ubuntu install and see if this is reproducible or just some intermediate issue.
