Thanks I will not remove, but I notice after change permission the first time that the file was removed..and not by me(probably an upgrade).
I have restored it from backup and give it the right permissions.

@keneda
Thanks

There is no need to reinstall, I had restored original perms copying them from the backup files(thanks rsync).
Only one question: on your phones this file exist?

/android/cache/legacy_channel

Thanks, I mark the thread solved
I'm lucky that i had a backup made with rsync so I had the correct permissions to restore
Just another question: is possible to download somewhere the system.img untouched for Ubuntu touch for Nexus5?

@keneda said in Strange permissions on /etc /usr with uid 1005 and gid 1006:

@pelenze
Ubuntu Touch is not a regular GNU/L distrib.
It's designed for smartphones and mobile devices (android native one at first), with system files read only and some other particularities.
This for user security reasons (this OS is for any users, like me, not only power linux users).

So is better to restore the old perms?

I see some bad permission on some system dir

/ instead of root 755 is 1005:1006 with 775 permission
/usr and /etc the same.

I have fixed it restoring the correct Linux permission

I see there are a lot of files with gid 1006 under android dir

I prefer to not touch those dirs, I have made a mistake to change the permissions on / and /usr ?
