19.04 false gid for user

  • 772

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
---snip

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

grep samba /etc/group
sambashare:x:1000:alex

and 

id 
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

and 

sudo groupmod -g 1000 alex

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

My question was already the answer.

id
uid=1000(alex) gid=1000(alex) Gruppen=1000(alex),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),117(lpadmin)
alex@Guilmon:~$
permissions 19.04

  1. 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.
