    Here are a few simple ways that can help fix the Ubuntu file system permission reset issue.

    I contacted the same guy whoWho helped solve the problem (an error in the script I wrote), and solved the problem, but you need to seek help from a group of experts. Be very careful!

    How do I reset chmod permissions?

    Use chmod -R 755 /opt/lampp/htdocs if you want to change permissions for all programs and directories at once.Use Discover /opt/lampp/htdocs -type d -exec chmod 755 ; if the number of file types used is very large.Otherwise use chmod 755 $(find /path/to/base/dir -develop d).In all situations, it is better to use the real one.

    My situation was easier to solve at first because I had a two-disk system (Ubuntu and my old Fedora install), but running the OS from a CD/DVD or USB stick should do the same thing.< /p >

    How do I fix chmod 777?

    Prepare to boot into Linux recovery mode. Boot into recovery mode.Chroot for recovery. Once we reach the rescue environment, enter “1” to continue positively.Recovery permission.

    First, I mounted my filesystems like this (don’t forget to create positional points):

    ubuntu reset file system permissions

    mount /dev/ubuntu/root $MPOINTmount /dev/ubuntu/home $MPOINT/home

  • Step 3: Click on the Restore button and wait for the process to finish

  • I then ran the following command (my problem was only in a few critical directories) to copy some permissions from the live community to the messy one (truth be told, in my case I installed a powerful Ubuntu system in Fedora Virtual Box and got the permissions there) :

    find /etc /usr /bin /sbin -exec statistic --format "chmod %a "$MPOINT%n"" ; > /tmp/restoreperms.sh
    (...)chmod 755 /mount/ubuntu//etc/pppchmod 755 /mount/ubuntu//etc/ppp/ipv6-upchmod 2750 640 /mount/ubuntu//etc/ppp/peerschmod /mount/ubuntu//etc/ppp/peers/providerschmod 755 /mount/ubuntu//etc/ppp/ipv6-up.dchmod 777 /mount/ubuntu//etc/ppp/resolv.conf(...)

    I haven’t tested this, but it should work, which is why owners don’t mention owner groups either. Something like:

    find /etc /usr /bin -exec stat --type 'chown $MPOINT%n' %u:%g ; > /tmp/restoreperms.sh^(...)chown root: root /mount/ubuntu//etc/obex-data-server/imaging_capabilities.xmlchown root: root /mount/ubuntu//etc/obex-data-server/capability.xmlroot chown:root dip:root /mount/ubuntu//etc/pppchown /mount/ubuntu//etc/ppp/ipv6-uproot chown: dip /mount/ubuntu//etc/ppp/peersroot chown: dip /mount/ubuntu//etc/ppp/peers/providerchown root: root /mount/ubuntu//etc/ppp/ipv6-up.dchown root: root /mount/ubuntu//etc/ppp/resolv.conf(...)

    Of course this website needs to make sure the UID and GID become the same on both systems, this shouldn’t be a problem for users and groups associated with the system.

    How do I reset permissions in Ubuntu?

    Run this sale to get access rights to every file/directory in the system: find and | xargs stat -c ‘chmod %a “‘%n””‘ > /tmp/chmod.sh. Copy the chmod.sh file to your computer along with the wrong permissions. Run this history chmod +x /tmp/chmod.sh && /bin/bash /tmp/chmod.sh.

    In addition, setting the property clears the SGID in addition to the SUID flags, which leads to some weird bugs (for example, you can’t run sudo unless the permission is 4755). You only need to set the permissions AFTER the environment owners, no talking. SAVEFill in the file permission information with the owner information.

    1. For this, it is important that the deployment disk is in sync with the version that the clients are usingnt, or at least worked well with the current version of Ubuntu.
    2. Now I have these commands in your own cron job that runs daily (may take weeks) to comply with the policy. This will make the plan easier next time, but greenery like the one I have now will never happen again. 😉 Something like this:

      0 12 * 5 . * /usr/bin/find / -exec /usr/bin/stat --format="/bin/chmod %a %n" ; |/bin/bzip2 > -k /tmp/restore_chmod.$(/bin/date +%w).sh.bz2

      ubuntu reset file system permissions

      0 13 * * 7 . /usr/bin/find versus -exec /usr/bin/stat --format="/bin/chown %U:%G %n" ; |/bin/bzip2 -c > /tmp/restore_chown.$(/bin/date +%w).sh.bz2

    `/usr/bin/find / -exec /usr/bin/stat --format="[ ! -l ] && /bin/chmod %a %n" ; -exec /usr/bin/stat --format="/bin/chown -h %U:%G %n" ; |/bin/bzip2 -c > /tmp/restore_fileperms.$(/bin/date +%w).sh.bz2`

    Note that square brackets in filenames (under locations, for example) may require additional history maintenance, and that chown may automatically override the setuid, setgid, and chmod components. In the latter case, which will break e.g. /bin/su i.e. /usr/bin/sudo, you may need to reorder the exec clauses above.

    It should be possible to get out of this mess without System reinstallation. Or rather, migrating a new system either to a USB flash drive or via Virutal (or Box), if your company has a dual-boot system.

    How do I reset default permissions in Linux?

    Open almost any terminal window.The directory change consists of a fragile read/write folder (I’m assuming the permissions fallback is in the same place).Enter some setfacl –restore=test_permissions command.Press Enter.

    I reposted by the same guy (the problem is a bug in a script I wrote) and fixed it, but you need to ask the expert group for help. Be very careful!

    Firstly, my dilemma was easier to resolve because I had a dual-boot platform (Ubuntu and my old Fedora installation), despite booting the system from a USB stick (or perhaps a CD/ DVD) should provide the same.

    I first set up my filesystems like this (remember to create elevation points): mount /dev/ubuntu/root $MPOINT mount /dev/ubuntu/home $MPOINT/home

    I then ran the following check (my problem only occurred in a few – critical – directories) for production-to-system permission versions, which caused a mess (actually, in my case, I installed an Ubuntu system in Virtual Box on Fedora and got permissions here):

    find /etc /usr /bin -exec specifi –format “chmod %a $MPOINT%n” ; > /tmp/restoreperms.sh

    (...)chmod 755 /mount/ubuntu//etc/pppchmod 755 /mount/ubuntu//etc/ppp/ipv6-upchmod 2750 640 /mount/ubuntu//etc/ppp/peerschmod /mount/ubuntu//etc/ppp/peers/providerschmod 755 /mount/ubuntu//etc/ppp/ipv6-up.dchmod 777 /mount/ubuntu//etc/ppp/resolv.conf(...)

    I haven’t tested it, so it should work for owner-owner groups as well. Something like:

    find /etc /usr /bin -exec stat ‘chown –arrangement %U:%G $MPOINT%n’ ; > /tmp/restoreperms.sh^

    (...)chown root: root /mount/ubuntu//etc/obex-data-server/imaging_capabilities.xmlchown root: root /mount/ubuntu//etc/obex-data-server/capability.xmlroot chown:root dip:root /mount/ubuntu//etc/pppchown /mount/ubuntu//etc/ppp/ipv6-uproot chown: dip /mount/ubuntu//etc/ppp/peersroot chown: dip /mount/ubuntu//etc/ppp/peers/providerchown root: root /mount/ubuntu//etc/ppp/ipv6-up.dchown root: root /mount/ubuntu//etc/ppp/resolv.conf(...)

    Of course you have to be careful, as the UID and GID are often the same on both systems, but this shouldn’t be a problem, especially for system-bound users and different categories.

    The key factor here is that you are using an installation disk that is in sync with the version you are using, or at least the current version of IE8.I now have these commands next to the cronjob that run every 24 hours (perhaps weeks) to easily store this information. This is Will often make it easier next time, but of course, as I did now, it will never happen again. 😉 Something like this:
