Re: [xubuntu-users] Installation Issues

I have used Unetbootin to create install USB drives.  The homepage is:
https://unetbootin.github.io/

When creating a USB the software it may seem to hang at a place, almost
like a loop, BUT it is NOT. Let it finish, it may take awhile.  I have
used Unetbootin 4 times to install 18.04 since April & worked w/o fail.

Re: [xubuntu-users] catfish issues

[don subscribe]

John,
Over the years I have copied the following syntax cheats that aid in my
command line searches.

find files or directories

find ~/ -type f -iname "somefile*.xyz" -print 2>/dev/null

find (the find command
~/ (look in: /home/user
-type f (files only
-type d (directory only
-iname (ignore case
-name (match case
"somefile*.xyz" (looking for, * wildcards, & don't forget
trailing/matching quote, it will error
-print (print to stdout
2>/dev/null (pipe 2nd print output to null bit bucket, this usually
comes to play when searching / root you will get many permission errors
& piping to /dev/null moves them to null, no print

man find     (=options

Find "string in directory"

grep -iHr "string*" ~/

~/ (look in: /home/user
-H, --with-filename (Print the file name for each match.)
-R,-r, --recursive
-i, --ignore-case

man grep     (=options


The command line is your friend,
Don

[xubuntu-users] Fresh install 18.04 with aptik

[don subscribe]

I had to perform a new install of Xubuntu 18.04 because my normal GUI
login would not accept my password.  I even tried changing the keyboard,
thinking the KB was bad.  I ssh'd into the box with the local IP
address.  Yes, I rebooted and tried again & again to no avail.  I could
key the GUI password, the screen would blank for a few seconds and then
re-display the login screen.  It was if the xubuntu session was not
initiated? If I had not been able to SSH into the box, I would have been
w/o a creeks paddle. I took the easy Aptik way and was back running in
half an hour.

I performed a clean install of 18.04 with Aptik Migration Utility:
http://www.teejeetech.in/p/aptik.html

I used the aptik command line to run a command that backed all my files
and settings to another drive:
sudo aptik --backup-all --basepath /mnt/tb364/htpc-aptik-backup/

I installed a new xubuntu 18.04 & installed aptik & openssh-server
sudo apt-add-repository -y ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install aptik

I restored from the backup:  (If backed to a USB drive, I would have no
need to change the backup location)
cd into the Aptik-backup directory  Note: the install changed the drive
mount point to :
cd /media/don/281bc72e-405b-4dab-a23c-6557d9b007fd (This partition
contained the Aptik-backup directory which had all my backup files and a
./restore-all.sh script.)

I ran the ./restore-all.sh  command and xubuntu desktop was back, like
magic.  My  /etc/fstab was restored, as well, along with the 4 other users.

I see no reason why anyone should do an upgrade 18.04 without using
Aptik on a clean install. 
I always donate a few dollars to the author.  Aptik has saved me many
times and is a great migration tool.

For all skeptics, I receive nothing from the Aptik author for the
recommendation,

Don

Re: [xubuntu-users] 18.04 destroying my M.2 SSD

[don subscribe]

My fstab= ext4  noatime,errors=remount-ro 0   1
I read through the solid_state_drive arch link and I think I should
check my logs for errors.

I checked the /etc/cron* dirs and saw no fstrim cron.weekly job.  That's
weird because I thought ubuntu defaulted to a cron.weekly fstrim job.
Now, I'm wondering whether the install knows the install drive is a SSD??

I looked on this 16.04 box (M.2 ssd as well, w/no issues) and I have a
cron.daily and cron.weekly jobs for fstrim!  I guess I should fix that. 

I manually ran the fstrim on the 18.04 box w/issues the other day and
saw 211 Gb trimmed.
Just now, I ran it again and would guess that it has been running idle
for 7 or 8 hours:
$ sudo fstrim -av
[sudo] password for don:
/: 211 GiB (226551054336 bytes) trimmed

Thanks,
Don

My fstab is set like yours. I have 16 Gb memory and I hav nothing
running except network.  This is a new install in which I have only
logged into, to start network.  I'm accessing from another box with open
shh and running iotop.
~$ cat /proc/sys/vm/swappiness
1

Thanks, Don

I use Firefox, cache disabled, but I am only logged in to a new install
and have started no programs. Email is not even configured.

[xubuntu-users] 18.04 destroying my M.2 SSD

[don subscribe]

When Xubuntu became available as download from xubuntu.org I installed
it to a new Asus motherboard with Samsung 250Gb M.2 960 evo SSD.  The
usb install took < 3.5 minutes.  Additional installs included i386 libs
for my backup software and openssh-client/server, iotop.  I only have a
basic xubuntu install. 

My hdd light never stops blinking with activity, every 2 sec.  I logged
disk io with iotop for as much as 12 hours.  I was alarmed to see that
fstrim -av after 12 hours shows 211 Gb trimmed.  I wonder how long this
SSD will survive in that box?

iotop shows r/w/ [jbd2/nvme0n1p2-] which is journaling for ext4 for
08:50:21, 08:50:27, 08:50:33, . . .n with imbeded kworker threads during
these times, which show 0.0/Bps.

I have reached the end of the internet in searches to solve this
problem.  I have searched at least 3 days/wk for the last month for
solutions & have tried some to no avail.  I have been an avid Xubuntu
user since 2006 and now have 5 Xubuntu boxes here.  When new LTS
releases are introduced I use Aptik to perform clean installs on all my
computers.

It pains me now to look for another Linux distribution, but this is
where I am at this point in time.
(I may try format to ext3 and install).  During my solution searches,
this problem arises back to Ubuntu 10.

Any Ideas?

Note: Installing 16.04 has same results on that box.
Samsung 960 evo was updated w/latest firmware which was already intalled.
I am writing this email on Asus M.2 box with an older motherboard and
M.2 SSD which has NO blinking hdd.  (imagine that! go figure)?

Re: [xubuntu-users] can't install an encrypted home folder

[don subscribe]

Are you sure that the home folder is NOT encrypted? To test it:
key in terminal: ls -A
(If file system is encrypted you will see a .encryptfs directory)

My home is encrypted, Ex:
don@don-m2:~$ ls -A /home
db2fenc1  db2fenc2  db2fenc3  db2inst1  db2inst2  don  .ecryptfs

The EASIEST way to do install a new system from existing is to use Aptik
