Title:
Chromium Snap & KDE Plasma 6: AppArmor Profile Update Needed
Status in chromium-browser package in Ubuntu:
Fix Committed
Bug description:
Ubuntu 22.04 LTS Jammy x64
I hope this is the correct package to assign this request to:
In KDE Plasma 6, the Chromium snap cannot longer access KDE Wallet to
decrypt its password store.
This makes all stored passwords unavailable as soon as the system is
upgraded from Plasma 5 to Plasma 6.
Chromium writes the following error messages to the console:
-----------------------------------------------------------------------------

-----------------------------------------------------------------------------
Followed by hundreds of messages as the following:
-----------------------------------------------------------------------------
ERROR:login_database.cc(1046) Password decryption failed, encryption_result
is 2
-----------------------------------------------------------------------------
It appears to work to "just" whitelist the new kwalletd module name in
/var/lib/snapd/apparmor/profiles/snap.chromium.chromium (and maybe
/var/lib/snapd/apparmor/profiles/snap.chromium.chromedriver ?)
followed by
$ systemctl restart apparmor
$ systemctl restart snapd.apparmor
$ systemctl restart apparmor
(Not sure if both of these are necessary, and if so, in what order.)
and completely restart Chromium.
The new KWallet section looks as follows - I only added the ",6" to
the patterns:
-----------------------------------------------------------------------------
# KWallet's client API is still in use in KDE/Plasma. It's DBus API relies
upon
# member data for access to its 'folders' and 'entries' and it therefore does
# not allow for application isolation via AppArmor. For details, see:
# - https://cgit.kde.org/kdelibs.git/tree/kdeui/util/kwallet.h?h=v4.14.33

I hope that at least this report may be found by other people running
into the same trouble I just did...
