yesterday i made a clean install of ubuntu19.04. Over /etc/fstab I mount my debianhome and make a bind mount to an folder.

In both systems the 1.user is the same name.

but I was suprised which permissions are ubuntu shown in the folder.

ls -al jd2/
total 12784
drwxr-xr-x  18 alex sambashare    4096 Mär 20  2019  .
drwxr-xr-x  22 alex alex          4096 Okt  28 08:23  ..
drwxr-xr-x   3 alex sambashare    4096 Okt  10  2016  .install4j
-rw-r--r--   1 alex sambashare 7950765 Mär 20  2019  Core.jar

I boot debian, but the gid is 1000 from my user, all okay there.

grep samba /etc/group


uid=1000(alex) gid=1001(alex) groups=1001(alex),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),117(lpadmin),1000(sambashare)

How can I fix it, without destroying the whole system?

sudo groupdel sambashare


sudo groupmod -g 1000 alex

Have I afterwards to change the rights in my $HOME? is think so.

stat .bashrc 
  File: .bashrc
  Size: 3771            Blocks: 8          IO Block: 4096   regular file

My question was already the answer.

uid=1000(alex) gid=1000(alex) Gruppen=1000(alex),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),117(lpadmin)

Obviously you can't rename "alex" to "alex" so you need to rename "1001" to "1000" instead. This answer appears to work for you:

Read the entire Q&A but in summary (if you agree it works for you) use:

find / -gid 1001 ! -type l -exec chgrp 1000 {} \;

You might also want to change the group name for GID 1001 to "alex2". This will make it easier to spot files you may have missed.

  • Nice try, but GID 1000 was blocked by group sambashare. I had to remove the group first. – nobody Oct 29 '19 at 11:13
  • @nobody Sorry I've never used samba but that might be the first problem to solve and the GID the second problem. – WinEunuuchs2Unix Oct 29 '19 at 11:26
  • Samba is not installt. Only a lonely lib. maybe an error in calamares. It is fixed, thank you. – nobody Oct 29 '19 at 11:32
