Hi Chris,

Because I could no longer install Debian 8 "Jessie" on new machine and
update the old machines, I migrate to Debian 10 "Buster" with KDE Plasma.
But I found lots of problems and would appreciate your help solve them:

1. "Buster" system freezes when I am running programs in various virtual desktop, especially YouTube. Is it a bug?

2. "Buster" no longer supports ecryptfs. Is there any other way to encrypt
a directory?

3. Some of regex commends that worked on old Debian Jessie do not work on "Buster". What's wrong?

4. Is there any way to install the old "Jessie"?

Regards


Henry

Did you update to Debian 9 and then to Debian 10? If you skipped releases
- there's no straightforward way to work out what's gone wrong, necessarily.

This might be better asked in debian-user: debian-project is perhaps
not the most appropriate place.

2. "Buster" no longer supports ecryptfs. Is there any other way to encrypt

You can always start again: install Jessie from the beginning then
update to the latest versions gradually. Back up / save any data
from the machine before you do so: the installation from new
will almost certainly wipe all data.

With every good wish

Note: it is best to ask these questions to an user mailing list. Here
you can get very few answers

if you want to migrate from Debian 8 to Debian 10 you must do two
migration: first from Debian 8 to Debian 9 and then from Debian 9 to
Debian 10

But I found lots of problems and would appreciate your help solve them:

1. "Buster" system freezes when I am running programs in various virtual desktop, especially YouTube. Is it a bug?

it is very hard to say something.
You must, at least, look at your logs and report if there are some wanings/errors when you do it. Also you can look at bugs on the program
you are using for having virtual desktop (note that bugs can be closed
after Buster release and so you don't have a patch for them in Buster).

If you have migrated from Debian 8 directory to Debian 10 you can have problems.

2. "Buster" no longer supports ecryptfs.

searching the package it seem that it was remove from the actual
oldstable (Buster) https://packages.debian.org/search?keywords=ecryptfs&searchon=names&suite=all&section=all

you can try to understand why from here: https://tracker.debian.org/pkg/ecryptfs-utils

and, if I don't mistake the answers is here: https://tracker.debian.org/news/1012612/ecryptfs-utils-removed-from-testing/ Bug #765854: ecryptfs-utils: Private directory not automatically
unmounted anymore on logout

Is there any other way to encrypt a directory?

probably fscrypt? https://packages.debian.org/search?suite=buster&arch=any&searchon=names&keywords=fscrypt

3. Some of regex commends that worked on old Debian Jessie do not work on "Buster". What's wrong?

but what you use for making regexp?
What regexp do not work anymore?

4. Is there any way to install the old "Jessie"?

https://www.debian.org/releases/jessie/

note that you don't have anymore security update so it is better to
install a more recent Debian version

the Jessie installer can be found here: https://www.debian.org/releases/jessie/debian-installer/

As I wrote it is best you write to a Debian user mailing-list to ask
these questions, for example debian-user in English: https://lists.debian.org/debian-user/
or you can select one in another language:
https://lists.debian.org/users.html

Ciao
